- **A connected learning workspace** — Home, Learning, and Resources connect Chat, Books, Reading, Practice, Task Board, Calendar, and Learning notebook with shared materials, progress, and learning context.
- **Grounded knowledge and reading** — Build versioned libraries with LlamaIndex, PageIndex, GraphRAG, or LightRAG, connect external knowledge sources, and learn beside documents, video, and audio with source-linked citations.
- **Partners and subagents** — Consult live agents such as Claude Code, Codex, and Grok CLI, import past conversations, or run persistent Partners with their own memory, resources, and IM channels.
- **Inspectable memory** — L1 traces, L2 facts, and L3 synthesis make personalization visible and editable, with evidence links you can audit in the Memory Graph.
- **Extensible by design** — Add personas, built-in or community skills, MCP services, CLI apps, and generation models through one agent-native runtime.

## 🚀 Get Started

Choose the installation path that fits how you want to use DeepTutor. Terminal-based installs share one runtime home: private settings live in `data/user/settings/` under the launch directory, or under `DEEPTUTOR_HOME` / `deeptutor start --home` when set explicitly. After starting the app, configure a provider and model in **Settings → Providers** and **Language models**.

<details>
<summary><b>Desktop — macOS and Windows (Preview)</b></summary>

**Open DeepTutor** bundles Python, Node.js, and the full learning workspace, so no terminal or separate runtime installation is needed. Download published desktop builds from the [latest GitHub Release](https://github.com/HKUDS/DeepTutor/releases/latest), choosing the installer for your computer below.

For development previews, open a successful [Desktop Release workflow run](https://github.com/HKUDS/DeepTutor/actions/workflows/desktop-release.yml?query=branch%3Adev) and download the matching **Artifact**. These previews require GitHub sign-in and expire after seven days; published release downloads do not.

| Your computer | Download target | Installer |
| --- | --- | --- |
| **Mac with Apple Silicon** | `macos-arm64` | Open the DMG and drag **Open DeepTutor** into **Applications**. |
| **Mac with Intel** | `macos-x64` | Open the DMG and drag **Open DeepTutor** into **Applications**. |
| **Windows x64** | `windows-x64` | Run the Setup `.exe`, or extract the portable ZIP and launch `Open DeepTutor.exe`. |

Windows preview builds are unsigned and may show a SmartScreen warning. See the [desktop guide](apps/desktop/README.md) for signing, local data, and source builds.

</details>

<details>
<summary><b>Docker — Fastest Full-App Trial</b></summary>

Run the full Web app without installing Python or Node.js:

```bash
docker run --rm --name deeptutor \
  -p 127.0.0.1:3782:3782 \
  -v deeptutor-data:/app/data \
  ghcr.io/hkuds/deeptutor:latest
```

Open [http://127.0.0.1:3782](http://127.0.0.1:3782). The named volume preserves settings and local data; only port `3782` is required for the Web app. See the [Docker guide](https://docs.deeptutor.info/get-started/docker/) for host workspaces, local model services, reverse proxies, and production deployment.

</details>

Use **Python 3.11–3.14** and **Node.js 20.9+**. In the modular 1.7.0 release, `deeptutor[full]` installs the Web app and CLI; bare `deeptutor` installs core chat and the SDK.

```bash
mkdir -p my-deeptutor && cd my-deeptutor
python -m pip install -U "deeptutor[full]"
deeptutor init     # ports + LLM provider + optional embedding/search
deeptutor start    # starts backend + frontend
```

Open the URL printed in the terminal, by default [http://127.0.0.1:3782](http://127.0.0.1:3782). Press `Ctrl+C` to stop both services.

**Upgrading from 1.6.15 or earlier:** stop DeepTutor, back up the runtime home, and uninstall a legacy `deeptutor-cli` package before installing the new family. Keep the same `DEEPTUTOR_HOME`, then run `python -m pip check` and `deeptutor module list`. See the [PyPI and migration guide](https://docs.deeptutor.info/get-started/pypi/) for the exact upgrade commands.

</details>

<details>
<summary><b>Source — Current Dev and Contributors</b></summary>

Use **Python 3.11–3.14** and **Node.js 22 LTS** to match CI and Docker.

```bash
git clone --branch dev https://github.com/HKUDS/DeepTutor.git
cd DeepTutor
python3 -m venv .venv && source .venv/bin/activate
python -m pip install --upgrade pip
python -m pip install -r requirements/full.txt
python -m pip install -e . --no-deps
( cd web && npm ci --legacy-peer-deps )
deeptutor init
deeptutor start --dev
```

Use `deeptutor start` without `--dev` for a production build. Optional dependencies are installed from the repository root, for example `python scripts/install_extras.py dev,partners,math-animator`. See the [source installation guide](https://docs.deeptutor.info/get-started/from-source/) for Conda, extras, and troubleshooting, or the [Agent Setup guide](docs-for-dev/AGENT_SETUP.md) to let a terminal-capable agent perform and verify the setup.

</details>

<details>
<summary><b>CLI — Terminal and Agent Use</b></summary>

For a minimal terminal installation, use the core wheel; no Node.js or Web frontend is required:

```bash
mkdir -p my-deeptutor && cd my-deeptutor
python -m pip install -U deeptutor
deeptutor init --cli
deeptutor chat
```

Core includes Chat, Ask Questions, the CLI, and the SDK; other capabilities and management commands require their matching feature modules. For the current `dev` source installation and optional dependencies, see the [CLI-only guide](https://docs.deeptutor.info/get-started/cli-only/). The [CLI reference](#%EF%B8%8F-deeptutor-cli--agent-native-interface) below covers one-shot runs and machine-readable output.

<details>
<summary><b>🏗️ System architecture</b></summary>

</details>

<details>
<summary><b>🏠 Home — Conversations, Tasks, Notes, and Calendar</b></summary>

Home is where daily work begins: talk to the tutor, organize next actions, and develop your own notes in the current workspace. Calendar provides an account-wide view while retaining the source workspace for study events.

<details>
<summary><b>💬 Chat — The Agent Loop You Actually Use</b></summary>

Chat is the default capability and where most work begins. A single thread can talk normally, call tools, ground itself in selected knowledge bases, read attachments, generate images, consult subagents, write notebook records, and continue with the same context across turns.

The tutor calls tools as needed and can pause to ask clarifying questions. **Customize page**, at the upper right, chooses the visible modes and Skills, MCP, Partners, Preferences, and voice-input controls. Under **Starting prompts**, add, edit, or remove the titles and prompts in Explain, Solve, Practice, Plan, and Research. Save applies your account preferences; Cancel discards edits, and Restore defaults brings back the original choices.

User-toggleable tools are `brainstorm`, `web_search`, `paper_search`, `zotero_search`, `reason`, and `geogebra_analysis` — plus `imagegen` and `videogen` once you configure the matching generation model. Contextual tools such as `rag`, `kb_files`, `knowledge_frontier`, `read_source`, `read_memory`, `write_memory`, `read_skill`, `load_tools`, `exec`, `web_fetch`, `ask_user`, `list_favorites`, `save_favorite`, `write_note`, `search_notes`, `question_bank`, `github`, `consult_subagent`, `workspace_list`, `workspace_read`, `workspace_search`, `workspace_present`, and `workspace_export` mount automatically when the turn has the right context.

Context comes in two kinds: **sticky session context** (capability, workspace or course, tools, knowledge bases, persona, model, and Reading / Mastery state) persists across turns; **references** (files, chat history, books, reading sections, notebooks, selected question-bank entries, imported agents) come from the `+` menu for one turn by default, or every turn when pinned. The voice button only transcribes the current message.

**Reasoning-only output limits.** The shared agent loop retries once when internal reasoning uses the output budget without an answer or tool action. The default `prompt` strategy keeps the same budget. To stop immediately, set `strategy: stop` under `capabilities.chat.reasoning_budget_recovery` in your runtime `settings/agents.yaml`. An explicit larger budget can help models that need more room, at the cost of potentially higher latency and usage:

```yaml
capabilities:
  chat:
    responding:
      max_tokens: 8000
    reasoning_budget_recovery:
      strategy: increase_output_budget
      max_tokens: 16000
```

The recovery limit must exceed the normal output limit and be at most 131072; choose a value supported by your model. It applies to one recovery call only, retains the existing round and request-timeout bounds, and leaves reasoning effort unchanged. The trace records the policy, old/new limits, effective per-call budgets, and accumulated usage. Visible answer truncation keeps its normal continuation. With the experimental `typescript-native` runtime, explicit `stop` or `increase_output_budget` policies select the shared Python effects host with the TypeScript scheduler before the turn begins; the result reports that compatibility reason.

With the full profile, Home keeps **Chat**, **Ask Questions**, **Quiz**, **Visualize**, and **Video Lesson** one click away; **Research** for cited reports and **Solve** for worked reasoning sit under *More Capabilities*. Select text in an answer to open **Little Tutor**, a focused sidebar thread that stays nested under the source conversation. With at least three sent messages, the left gutter shows a tick for each question when space allows; hover to preview, click to jump back, or use **Alt/Option + ↑/↓** to move between questions.

</details>

<details>
<summary><b>✅ Task Board & Calendar — Organize Daily Learning</b></summary>

**Task Board** tracks study tasks in To do, In progress, and Done, with notes, drag-and-drop or keyboard-accessible move controls, and a restorable archive. Tasks stay in the current workspace and require no model configuration.

**Calendar** keeps personal study sessions, repeating events, and reminders together, with `.ics` export for Apple Calendar, Google Calendar, Outlook, and Thunderbird. Workspace overlays such as task due dates and reviews remain connected to their source workspace.

</details>

<details>
<summary><b>✍️ Learning Notebook — Pages, Sources, and Dito</b></summary>

The Learning notebook, formerly Co-Writer, organizes your own writing into pages, subpages, and blocks within the active workspace. Import Word documents, arrange a page tree, and insert original records from Favorites as evidence. Pages keep their save status visible and export as Markdown or Word; interactive content becomes static in Word.

**Export flashcards to Anki.** Notebook pages can include Flash Cards. On a page that has them, open the page menu and choose **Export flashcards (Anki)**. From the notebook review queue, choose **Export all for Anki**. In Anki, use **File → Import** and select the downloaded `.txt` file. Cards land in a deck named `DeepTutor::<note title>` with front/back fields, tags, and math preserved. Re-importing the same file updates existing cards instead of duplicating them. DeepTutor's own review schedule is not included.

Discuss a passage or block with **Dito**: ask for an explanation, example, rewrite, or practice question. Conversations remain attached to the relevant page and line. Review proposed changes before accepting them, or insert an answer below the line and keep working. Favorites preserve source records; the notebook is where you build your own understanding.

</details>

<details>
<summary><b>🎓 Learning — Books, Paths, Reading, and Practice</b></summary>

Learning is the current workspace's study area. Create an activity from **Learning → New learning**, then reopen it from **All learning** with its progress, conversations, and source context intact.

| Activity | Use it for | What you keep |
| --- | --- | --- |
| **Book** | Build a structured, interactive book from selected sources | Editable chapters, typed blocks, reading progress, and Page Chat |
| **Mastery Path** | Break a learning goal into topics and guided study | A knowledge-point map, topic conversations, and mastery evidence |
| **Immersive Reading** | Work beside a document, web page, video, or audio source | Source-linked conversations, verified citations, highlights, notes, and progress |
| **Practice** | Review collected or imported questions | Answers, mistakes, recall ratings, and the next review date |

<details>
<summary><b>📖 Book — Living Books from Your Materials</b></summary>

Book turns selected sources into an interactive **living book** — not a static PDF, but a reading environment built from typed blocks. A book can start from knowledge bases, Favorites, question banks, or chat history; the creation flow proposes a chapter outline before content is generated, so you review the shape instead of accepting a blind one-shot output.

Each chapter compiles into editable typed blocks — text, callouts, quizzes, flash cards, timelines, code, figures, interactive HTML, animations, concept graphs, deep dives, and user notes — with its own Page Chat. Insert, move, regenerate, rewrite, or switch a block type; selected passages enter a reviewable learning-capture inbox. Progress, bookmarks, quiz attempts, captures, and Page Chat stay private per reader even when an admin book is shared read-only or for collaborative editing; shared deletion stays admin-only. Any book exports to Markdown, long compiles pause and resume, `deeptutor book health` flags source drift, and `deeptutor book refresh-fingerprints` refreshes the source baseline.

</details>

<details>
<summary><b>🗂️ Resources — Materials and Saved Learning Records</b></summary>

Resources is the current workspace's reusable library. Keep original material, saved results, and learning records here so they can be attached to new conversations and activities without mixing projects.

<details>
<summary><b>📚 Knowledge Center — Multi-Engine RAG Libraries</b></summary>

Knowledge bases are the document collections behind RAG — they ground Chat turns, Learning notebook edits, Book generation, and Partner conversations. What's distinctive is a **choice of retrieval engines**: **LlamaIndex** (the default, hybrid vector + BM25 with optional cross-encoder reranking and exact-flat or HNSW FAISS indexes), **PageIndex** (reasoning retrieval with page-level citations, hosted or self-hosted OSS), **GraphRAG** and **LightRAG** (knowledge-graph retrieval), **LightRAG Server** (retrieval offloaded to an external LightRAG instance you connect over HTTP), **WeKnora** (retrieval from a knowledge base in your self-hosted deployment, without a local index or document copy), **Tencent IMA** (a library you curate in IMA — searched, browsed, and written back to over its OpenAPI), **MarginNote 4** (your MN4 study data — documents, excerpts, mind-map cards and the links between them — pushed in by the app's Add-on and navigated with dedicated tools), **Kiwix** (a searchable ZIM archive served over HTTP without local indexing), or a linked **Obsidian** vault the tutor reads and writes in place. Each KB is bound to one engine.

Migrating an existing Obsidian, Hermes, or Markdown library? See [Knowledge migration guide](./docs-for-dev/KNOWLEDGE_MIGRATION.md) for connected-vault and indexed-copy paths.

Creating a KB, you can **create new** (upload and index documents), **link existing** (reuse an index in place), or **connect Kiwix** (search one served ZIM archive on demand). Choose its storage workspace at creation; an existing KB can move between workspaces after a preview, keeping assignments and saved references. A KB can also track **GitHub repositories** (repo, branch, glob) or **documentation-site URLs** (bounded crawl depth and page count, re-synced every 24 h by default); sync hash-diffs added, changed, and removed content so followed documentation stays current without re-uploading, and **linked folders** pick up new or changed local files on sync. Re-indexing writes a new flat `version-N` directory and keeps prior ones, so a working index is never destroyed mid-rebuild. A single document can be removed even from an **error**-state base — dropping a file that failed to parse without a full delete-and-rebuild. Document parsing — Text-only, MinerU, Docling, Tika, markitdown, PyMuPDF4LLM, or LiteParse — and an optional image-description model are chosen in **Settings → Knowledge & documents**, with local model downloads off by default. Docling can also run in **remote** mode against a Docling Serve server (no local install or models needed), configured on that page (`mode=remote`, a server base URL, and an optional API key) or the `DOCLING_MODE` / `DOCLING_API_BASE_URL` / `DOCLING_API_TOKEN` environment variables. Tika is remote-only and points at the Apache Tika server configured on that page. The CLI mirrors the lifecycle with `list/info/create/connect-kiwix/add/search/eval/eval-diff/set-default/delete`, source add/remove commands, `list-sources`, and `sync`.

The built-in LightRAG engine is installed with `pip install 'deeptutor[rag-lightrag]'`. That extra contains the supported LightRAG SDK but does not install MinerU. Choose MinerU independently in Document Parsing and either configure its cloud mode or install its current local CLI when structured parsing is wanted. MinerU accepts PDF, common raster images, DOCX, PPTX, and XLSX; the legacy `magic-pdf` command remains PDF-only. Text-only and the other parsing engines do not require MinerU.

Native LightRAG queries and incremental indexing require the embedding configuration recorded by the published index, including the model, dimension, and endpoint identity. If it changes, restore the original configuration or rebuild with the current embedding; indexes without a recorded embedding identity require a rebuild. The knowledge-base detail and index-version views show recovery guidance, while files remain available for viewing and download.

**Scoring a knowledge base.** With several engines available, "which one retrieves best here?" is an empirical question — so `deeptutor kb eval` answers it. Write a QA set (one JSON object per line: a `query` plus the `gold` passages an ideal retrieval should return), then score the KB with `deeptutor kb eval <name> --dataset qa.jsonl --top-k 5 [--mode hybrid] [--save baseline.json]`. Each case is retrieved through the same path a chat turn uses, its ranked citations are matched against the gold passages using exact text or lexical overlap (thresholds are tunable with `--min-ratio`; semantic equivalence is not assessed), and the run reports **Recall@k / Precision@k / nDCG@k / MRR / MAP / Hit@k**. Metrics are pure functions over the ranking; no model judges the output. Compare saved reports with `deeptutor kb eval-diff baseline.json candidate.json` for per-metric and per-case changes. Use `--rewrite off` or `--rewrite standalone` on `kb eval` to compare original and rewritten queries; reports retain rewrite provenance. Cases whose search failed (a missing index, bad credentials) carry no score and are reported separately rather than dragging the means down. PageIndex uses reasoning as retrieval and returns no ranked chunks, so it is excluded.

```jsonl
{"query": "Why do transformers scale attention?", "gold": ["Scaling keeps the dot products from growing with the dimension."]}
```

</details>

<details>
<summary><b>🗃️ History, Favorites, Journal, and Question Bank</b></summary>

**Chat History** reopens conversations with their original learning context. **Favorites** preserves useful original conversations and results in movable collections with Markdown export, ready to insert into a Learning notebook. The **Learning journal** records the current mission, session handoff, and confirmed learning records. The **Question Bank** organizes questions, answers, explanations, and mistakes; select a set for **Learning → Practice** to review weak areas and schedule repetition.

</details>

<details>
<summary><b>🤝 Partners — Persistent Companions Across Workspaces</b></summary>

Partners belong to the account rather than one subject workspace. Each companion keeps its own identity, instructions, model policy, relationships, and channels while using either a private library or an existing workspace's resources.

<details>
<summary><b>Identity, Workspace Resources, Groups, and Channels</b></summary>

Every inbound Web or IM message becomes a normal `ChatOrchestrator` turn — a Partner is "a chat that has a personality and a phone number." Its `SOUL.md`, model selection, tool policy, and library remain editable after creation. A private Partner workspace copies assigned knowledge bases, skills, and Favorites collections; a bound workspace shares its current files and resources instead. Soul, conversations, and relationship memory stay separate in either mode.

**Partner Groups** bring two or more Partners into one shared conversation with distinct seats, selectable discussion and shared-memory modes, and durable history. Authenticated users keep private Partner sessions and relationship memory even when a companion is shared.

Schema-driven channels connect companions to Feishu, Telegram, Slack, Discord, DingTalk, QQ/NapCat, WeCom, WhatsApp, Zulip, Mattermost, Matrix, Mochat, and Microsoft Teams, depending on installed extras and credentials. Browser-based setup supports QR onboarding for selected channels. A Partner can also be connected through **Personalization → My Agents** and consulted from a normal Chat turn.

</details>

<details>
<summary><b>🧭 Personalization — Reusable Behavior and Connections</b></summary>

Personalization follows the account across workspaces. Choose how the tutor should behave and which agents, skills, services, applications, and memories it may reuse; workspace and conversation selections can narrow that access further.

<details>
<summary><b>🧑‍🚀 My Agents — Consult Live Agents and Import History</b></summary>

**Connect a live agent** — Claude Code, Codex, Grok CLI, Antigravity, Kimi, opencode, MiMo Code, Hermes Agent, OpenClaw, DeepSeek Harness, or a Partner — and consult it from a Chat turn. DeepTutor runs the selected agent and streams its work into the Activity panel through `consult_subagent`; the Agent chip or `@` keeps the connection attached to the session. Local harnesses use their own authentication, working directory, and session storage.

**Import past conversations** from ChatGPT, Claude Code, and Codex as searchable, resumable references. ChatGPT uses an official `conversations.json` export; Claude history is selected by project or working directory, and Codex history by date. Reference an imported conversation through `+` → My Agents without turning it into DeepTutor's own voice.

</details>

<details>
<summary><b>🎭 Personas, Skills, MCP Services, and CLI Apps</b></summary>

**Personas** reuse a voice, teaching style, or response policy and can also seed a Partner's soul. **Skills** package repeatable workflows as `SKILL.md` playbooks, with account-shared and workspace-local libraries. **Import from EduHub** browses community skills and installs them through a security gate (see [Ecosystem](#-ecosystem--eduhub--the-skills-community)).

**MCP Services** authorize external tools, while **CLI Apps** expose installed programs from the [CLI-Anything](https://github.com/HKUDS/CLI-Anything) catalog through the execution sandbox. Workspace assignments and user grants determine which resources each turn may use.

</details>

<details>
<summary><b>🧠 Memory — Inspectable Personalization</b></summary>

Memory is a file-backed, three-layer system you can read, curate, and audit — deliberately *not* a hidden vector store. **L1** is the workspace mirror plus an append-only event trace (`trace/<surface>/<date>.jsonl`); **L2** is per-surface curated facts (`L2/<surface>.md`) with references to L1 entities; **L3** is cross-surface synthesis (`L3/<profile|recent|scope|preferences>.md`) that records its contributing L2 surfaces.

The Memory Graph shows the whole pyramid — L3 synthesis at the centre, L2 in the middle ring, L1 traces on the outside — with exact L2 → L1 evidence edges and L3 → contributing-surface links. Memory is tracked across `chat`, `notebook`, `quiz`, `kb`, `book`, partner, and `cowriter` surfaces; the consolidator's Update / Audit / Dedup budgets are tuned in **Settings → Memory**.

</details>

<details>
<summary><b>⚙️ Settings — One Control Plane</b></summary>

Settings is the operational control plane, opening on **General** for interface and model output language. Its searchable navigator links to independent pages: **Personal** covers Workspaces, Data migration, Appearance, and Usage statistics; **Learning & conversation** covers starting points, attachments, Video Learning, learner and guardian controls, Learning progress, and Memory; **Models & services** covers Providers, Language models, Task models, Embedding, Search, Voice, and Multimodal generation; **Features & integrations** covers tools, capability parameters, Partners & agents, and Knowledge & documents. **System** holds Network, Runtime status, and About; **Archived chats** lets you search, restore, or permanently delete archived conversations. Runtime status contains backend health, resident memory, and the **Readiness** matrix grading capability blockers, warnings, and suggestions. Workspaces keeps topic files and learning state separate, with verified migration and export under Data migration. A **provider** holds a vendor's address and credential for reuse by its service models; the model pages choose saved providers and configure model names and capabilities. **Task models** pin a small, fast model for automatic work — from naming conversations and writing starting points to Math Animator and Video Lesson repairs — and resolve to the active default when empty. Voice groups speech synthesis and transcription; Multimodal generation groups image and video models. Partners & agents configures local harnesses and a remote Hermes gateway.

**Vietnamese:** In **Settings → General**, choose **Tiếng Việt** for **Interface language** and select **Apply changes**. **Model output language** is independent: choose **Tiếng Việt** there for Vietnamese replies, or keep another reply language while using the Vietnamese interface. Reply quality depends on the selected model's Vietnamese support.

**NVIDIA NIM embeddings:** Select **NVIDIA NIM** under **Settings → Embedding** for text retrieval with `nvidia/nemotron-3.5-embed-8b`. The default endpoint is `https://integrate.api.nvidia.com/v1/embeddings`; a custom full endpoint is used as entered. Indexing sends `input_type=passage`, retrieval sends `input_type=query`, and connection checks default to passage. The hosted model defaults to 4096 dimensions and accepts a configured dimension from 1 to 4096. This binding supports text only; image embeddings and self-hosted model-specific options are outside its scope. Existing OpenAI-compatible profiles retain their previous request behavior; select the NIM binding and re-index when switching an existing knowledge base. See the [NVIDIA API contract](https://docs.api.nvidia.com/nim/reference/nvidia-nemotron-3_5-embed-8b-infer).

**Xiaomi MiMo speech.** Add a Xiaomi MiMo provider with `https://api.xiaomimimo.com/v1` and its API key, then add `mimo-v2.5-tts` under Settings → Voice. Choose a preset such as `mimo_default`, `冰糖`, or `苏打`, use `wav` or `pcm16` output, and audition it before applying. Voice instructions control style and speaking speed. This adapter supports preset speech only; voice design and voice cloning require separate models and are not supported. If an older MiMo speech model was configured through the generic OpenAI-compatible adapter, recreate its speech entry using the Xiaomi MiMo provider so it uses the chat-completions protocol. See the [official MiMo speech guide](https://mimo.mi.com/docs/zh-CN/quick-start/usage-guide/audio/speech-synthesis-v2.5).

**MiniMax speech** — in Settings → Voice, choose MiniMax for text-to-speech and select `speech-2.8-hd`. Configure a MiniMax API key and explicitly select a system voice or enter a custom voice ID. The API base defaults to `https://api.minimax.io/v1`; for the China region use `https://api.minimaxi.com/v1`. Read-aloud and voice previews use the native speech endpoint, with MP3, WAV, FLAC or PCM output, sample rate, speed and language controls. See the [MiniMax speech API](https://platform.minimax.io/docs/api-reference/speech-t2a-http) for voice IDs and account availability.

**Selected-text speech:** select a word or passage in Chat, Mastery Path, or Reading and click **Read aloud** in the nearby toolbar. Click **Stop** to cancel synthesis or playback. This reads only the selection, uses the active TTS provider and voice configured under **Settings → Voice**, and does not send a chat turn. Selection alone never starts playback. A working speech service is required; this feature does not install or select one for you.

**Video Learning** under Settings → Learning & conversation configures YouTube captions and Invidious access for Reading. To use Invidious, set its administrator-managed backend API origin (for example `http://127.0.0.1:3000`) and browser-accessible public origin, test the connection, select Invidious, and save. **Browse Invidious** in Reading's add-material dialog searches videos and accesses connected subscriptions and playlists. YouTube playback uses the official privacy-enhanced player; missing captions remain visible and limit the tutor's evidence without blocking native playback. In a source checkout, run `python scripts/install_extras.py video-learning` for the default YouTube caption loader. Existing Watching links migrate into Reading with conversation history, compatible transcripts, notes, and progress preserved; new timestamp notes are Reading annotations. Bilibili uses its own playback and caption path.

Most sections use a draft-and-apply flow, so you can test a provider before committing it. You can also just ask in Chat: the assistant reads the current configuration, applies a change, and says whether it needs a restart or a re-index — probing a new model before it commits, so it cannot switch itself onto something unreachable. API keys never pass through the model, which opens the matching form for you instead. Four themes ship in the box — Default, Cream, Dark, and Glass. Project-root `.env` files are intentionally ignored; runtime configuration lives under `data/user/settings/*.json` unless `DEEPTUTOR_HOME` or `deeptutor start --home` points the app elsewhere.

**OpenAI Codex OAuth (experimental).** Adding **OpenAI Codex** under Settings → Providers opens a browser sign-in that runs against your own ChatGPT plan, so no `OPENAI_API_KEY` is needed. Tokens live only in `data/system/user-secrets/<owner>/private/openai-codex/` — in the multi-container Compose deployment, outside every tree the exec sandbox can reach — and DeepTutor never reads or modifies your `~/.codex` CLI login. The model list comes from that account's live catalog; signing in publishes the profile but only becomes the active model when no LLM is configured yet. Because a token authorizes one person's plan, the profile is not shareable through user grants — each account signs in for itself, ordinary users included: their sign-in card sits under Providers, and the resulting models, catalog, and sign-out stay private to that account.

On sign-in and **Refresh models**, DeepTutor reads the latest stable `@openai/codex` version from the official npm registry and uses it as the catalog request's `client_version`. This is metadata-only: it does not install, download, or upgrade the Codex CLI, and the npm request carries no OAuth credentials. Discovery has a three-second deadline and a 64 KiB response limit. If it fails, DeepTutor uses the last successful version for that account, or its built-in fallback when none is cached. Only a successfully parsed live catalog saves a new version; validators are never reused across versions or credential generations. A version rejection or incompatible catalog structure permits one retry with the previous version; authentication, rate-limit, and TLS failures are not retried as version problems. A failed manual refresh reports an error rather than presenting an old cached catalog as refreshed.

Successful version history survives same-account token renewal and catalog authentication errors, without making invalidated model data or ETags usable again. Signing out clears that account's local cache, including the version history. Ordinary status reads and inference do not query npm. New catalog entries do not replace a model you already selected or restart learning sessions; appearing in the catalog does not establish full inference-protocol compatibility. There is no background version updater or user version setting.

Default local Docker and Podman deployments use separate loopback networks and need a temporary bridge during sign-in. Follow the [temporary local Codex OAuth bridge guide](./docs-for-dev/CONTAINERIZATION.md#temporary-local-codex-oauth-bridge) for the exact Docker, Compose, Podman, and teardown commands.

For a remote deployment, the browser's `localhost` and the server's `localhost` are different machines, so an ordinary reverse proxy alone cannot carry the browser's localhost callback to the server. Use an SSH tunnel as the callback bridge. The tunnel reaches the already-published Web port; Next.js rewrites only the exact callback path to the public callback broker, and the broker validates `state` before routing to the original OAuth operation. The callback listener remains on the backend loopback, ports `1455` and `1457` are not published, and this path supports the default Docker bridge network.

```bash
ssh -N -L 1455:127.0.0.1:3782 <ssh-user>@<server-host>
```

If DeepTutor reports fallback callback port `1457`, use:

```bash
ssh -N -L 1457:127.0.0.1:3782 <ssh-user>@<server-host>
```

Run only the one command that matches the actual callback port; never run both. `3782` is only the example Web port: it is the configured frontend/container port reported as `callback_forward_port`. That value does not guarantee that the same port is listening on the SSH host's `127.0.0.1`. If Docker or Podman publishes a different host port, or a reverse proxy listens on a different port, replace only the right-hand target port (`3782` above) with the Web port actually listening on the SSH host's `127.0.0.1`; keep the left-hand callback port as `1455` or `1457`. `<server-host>` is the SSH host whose loopback owns that listening port. If the browser URL names a reverse proxy or load balancer, replace it with the correct SSH frontend host.

The CLI prints the tunnel command and then immediately tries to open the browser. On a remote deployment, keep the authorization page open without completing it, establish the printed tunnel in another terminal, and only then continue authorization.

Remote-topology detection has a localhost boundary. If Web itself is reached through an SSH or IDE localhost forward, the browser cannot tell that the server is remote. For the current Web operation, leave its authorization page unfinished, read `redirect_uri` in that operation's authorize URL to identify callback port `1455` or `1457`, and create the second tunnel from that local port to the actual Web port. Alternatively, cancel that Web operation and start a new one with the CLI; the CLI output belongs to the new operation and must not be used for the existing Web operation. Quota errors and catalog failures are reported as-is and never fall back to a paid provider. This compatibility path is experimental: the upstream interface may change.

### 🛠️ Administration & Shared Deployments

The five areas above describe the learner-facing workspace. The following deployment controls are for administrators hosting DeepTutor for multiple users.

<details>
<summary><b>👥 Multi-User — Shared Deployments</b> · optional auth, isolated per-user workspaces</summary>

Authentication is **off by default** — DeepTutor runs single-user. Turn it on and one `data/` tree hosts an admin workspace, isolated per-user workspaces, and partner workspaces side by side:

```text
data/
├── user/                    # Admin workspace + global settings
├── users/<uid>/             # Per-user scope: chat history, memory, notebooks, KBs
├── partners/<id>/workspace/ # Partner (synthetic-user) scope
├── cli-apps/                # Installed CLI apps, mounted read-only into the sandbox
└── system/                  # auth · grants · audit · user-secrets/<owner> (OAuth tokens)
```

The **first registered user becomes admin** and owns model catalogs, provider credentials, shared knowledge bases, skills, canonical shared books, and per-user grants. Admin-created local users choose Standard, Learner, or Custom. Learner locks learning capabilities and material policy, adds an adaptive profile, and supports revocable device credentials with expiry and daily limits; authorized guardians can view reports, approve materials, and reset credentials. Other users get isolated workspaces plus scoped models, KBs, skills, partners, and shared-book access without receiving raw API keys. If `auth.json` already carries a `username` + `password_hash`, that account *is* the admin: `/register` stays closed and accounts created from `/admin/users` are always `role=user` until you promote them.

**Enable it:** turn auth on in `data/user/settings/auth.json`, restart `deeptutor start`, register the first admin at `/register`, then add users from `/admin/users` and assign models, KBs, skills, partners, tool/MCP/CLI-app policy, and code-execution access through grants; configure shared books under each user's **Book access** panel.

For split private/public origins, set `auth.private_login_hosts` (or `AUTH_PRIVATE_LOGIN_HOSTS`) to the private frontend hosts that may show password sign-in and registration. The frontend forwards the incoming HTTP `Host` to the backend as its frontend-host assertion. Preserve the browser's `Host` through your reverse proxy, and make the public ingress reject requests naming a private host; do not expose a raw Next.js port that accepts arbitrary `Host` values. HTTP `Host` can be forged by a direct client, so private-host authorization depends on that ingress boundary. The backend accepts frontend-host assertions only from loopback by default. If the Web frontend connects from another container or host, set `AUTH_TRUSTED_FRONTEND_PROXY_IPS` to that frontend proxy's exact IP address on the backend process (comma-separated for more than one). This replaces the defaults; include `127.0.0.1,::1` if local frontend connections are also needed. Keep the backend API private to the frontend proxy and do not include general client networks in this list. When `private_login_hosts` is non-empty, an authenticated user on a private origin can open **Profile → Public device sign-in** and create a short-lived, host-bound pairing link for an HTTPS public origin. The public `/handoff` page exchanges the one-time code for an equally short JWE ticket in a POST body, consumes the ticket once, and receives the normal HttpOnly session cookie.

> PocketBase stays a single-user integration — keep `integrations.pocketbase_url` blank for multi-user deployments unless you've wired up an external user store.

</details>

## ⌨️ DeepTutor CLI — Agent-Native Interface

One `deeptutor` binary, two ways in: an interactive **REPL** for people who live in the terminal, and structured **JSON** for other agents that drive DeepTutor as a tool. Same capabilities, tools, and knowledge bases either way.

<details>
<summary><b>Drive it yourself</b></summary>

`deeptutor chat` opens an interactive REPL and selects a mode with `--capability`; `deeptutor run <capability> "<message>"` takes that capability as its first positional argument and exits after one turn. Both accept `--tool`, `--kb`, `--config`, and `--workspace` to select a registered workspace.

```bash
deeptutor chat                                              # interactive REPL
deeptutor chat --capability deep_solve --kb my-kb
deeptutor run chat "Explain the Fourier transform" --kb textbook
deeptutor run chat "Find recent work beyond this material" --kb textbook
deeptutor run deep_research "Survey 2026 papers on RAG" \
  --config mode=report --config depth=standard
```

`--kb` supplies context for automatic RAG and Knowledge Frontier tools; Frontier needs both knowledge and research modules. `--tool` selects user-toggleable tools. Enabled modules also provide KB, session, partner, skill, notebook, memory, and config commands.

</details>

<details>
<summary><b>Let an agent drive it</b></summary>

DeepTutor is built to be *operated by another agent*. Add `--format json` to any `run` and each turn streams **NDJSON — one event per line** (`content`, `tool_call`, `tool_result`, `done`, …), every line tagged with its `session_id`. Runs are headless-safe: an `ask_user` pause with no TTY auto-resolves with an empty reply instead of hanging.

```bash
# One shot, machine-readable
deeptutor run deep_solve "Find d/dx[sin(x^2)]" --tool reason --format json

# Chain turns in one stateful session — capture the id, reuse it
SID=$(deeptutor run deep_research "Survey 2026 papers on RAG" \
  --config mode=report --config depth=standard --format json \
  | jq -r 'select(.type=="done").session_id')
deeptutor run deep_question "Quiz me on that survey" --session "$SID" --format json
```

The repo ships a root [`SKILL.md`](SKILL.md) — a compact handover doc for the CLI. Ask your agent to read it explicitly; its [Agent Setup guide](docs-for-dev/AGENT_SETUP.md) covers installation and configuration. You can also wrap `deeptutor run` as a tool in a LangChain / AutoGen loop. Full recipes: [Agent Handoff](https://deeptutor.info/docs/cli/agent-handoff/).

</details>

<details>
<summary><b>Opt-in visual review for Manim animations</b></summary>

Set `enable_visual_review=true` to inspect rendered frames for overlap, readability,
and framing, then feed detected issues into the existing code repair loop:

```bash
deeptutor run math_animator "Animate a sine wave" --config enable_visual_review=true
deeptutor run visualize "Animate a sine wave" \
  --config render_mode=manim_video --config enable_visual_review=true
```

The option defaults to `false`. It also works with `output_mode=image` for
`math_animator` and `render_mode=manim_image` for `visualize`. Other visualizers,
including the general `auto` loop, ignore it. Manim's optional dependencies are
still required.

For SDK turns, pass `config={"enable_visual_review": True}` in the `TurnRequest`
sent to `DeepTutorApp.start_turn()`. API clients use the same `config` object with
JSON `true`. For book animation blocks, set
`params={"enable_visual_review": True}` on the animation `Block`.

Review adds vision model calls and may add repair calls and re-renders, increasing
cost and latency. It uses the existing limit of four retries, with a 120-second
review timeout and a 180-second repair timeout. If no frames are available or the
configured review model cannot inspect images, review is skipped with a summary.
An unsuccessful review after all retries returns the best available render and its
failed review result; a review timeout follows the existing render error/retry path.
Capability results expose `render.visual_review`; book blocks retain the same
review data in `metadata.visual_review` (`null` when review did not run).

</details>

<details>
<summary><b>Command reference</b></summary>

The table covers the full installation and optional add-ons; commands and capabilities require their modules to be enabled. Core provides `chat` and `ask_questions`.

| Command | Description |
|:---|:---|
| `deeptutor init [--non-interactive] [--home PATH]` | Run the setup wizard, or create missing defaults without prompts |
| `deeptutor doctor [--online]` | Check whether the runtime is ready to start a session; `--online` also probes the configured model provider, `--format json` prints the report |
| `deeptutor start [--home PATH] [--dev] [--detach] [--no-browser]` | Launch backend + frontend together; optionally detach or suppress browser opening |
| `deeptutor stop [--home PATH]` | Stop a launcher started with `--detach` |
| `deeptutor serve [--port PORT]` | Start only the FastAPI backend |
| `deeptutor module list/install/uninstall/enable/disable` | Inspect modules and change them with DeepTutor stopped; source checkouts support enable/disable |
| `deeptutor workspace show/set/reset` | Inspect, select, or restore the per-user Content Workspace |
| `deeptutor run <capability> <message>` | Run a single capability turn (`chat`, `ask_questions`, `deep_solve`, `deep_question`, `deep_research`, `visualize`, `math_animator`, `video_lesson`, `mastery_path`, `immersive_reading`, `audio_overview`); add `--format json` for NDJSON output |
| `deeptutor chat` | Interactive REPL with capability, tool, KB, notebook, and history controls |
| `deeptutor partner list/create/start/stop` | Manage IM-connected partners |
| `deeptutor kb list/info/create/connect-kiwix/add/search/eval/eval-diff/set-default/delete/list-sources/sync` | Manage knowledge bases, connect Kiwix archives, score and compare retrieval runs, and synchronize registered GitHub/web sources (with source add/remove commands) |
| `deeptutor skill search/install/list/remove/login/logout/publish/update` | Manage skills, install from hubs, and publish your own (`eduhub:<slug>` by default, see Ecosystem) |
| `deeptutor memory show/clear` | Inspect L2/L3 memory docs or clear L1/all memory |
| `deeptutor session list/show/open/rename/delete` | Manage shared sessions |
| `deeptutor notebook list/create/show/add-md/replace-md/remove-record` | Manage notebooks from Markdown files |
| `deeptutor book list/health/refresh-fingerprints` | Inspect books and refresh source fingerprints |
| `deeptutor plugin list/info/state/search/show/install/approve/enable/disable/rollback/uninstall` | Inspect tools and capabilities; manage reviewed plugin packages and their permission approvals |
| `deeptutor config show [--home PATH]` | Show resolved runtime configuration with credentials redacted |
| `deeptutor config providers` | List supported setup providers and defaults as JSON |
| `deeptutor config apply FILE [--check] [--home PATH]` | Apply setup JSON without prompts, or validate it without writing settings |
| `deeptutor provider login <provider>` | Provider auth (`openai-codex` OAuth login; `github-copilot` GitHub device login; `codebuddy` validates CodeBuddy SDK auth and starts login when needed) |

GitHub Copilot credentials belong to the signed-in DeepTutor owner and live only at
`<runtime-home>/data/system/user-secrets/<owner-id>/private/github-copilot/credentials.v1.json`,
outside sandbox workspaces. CLI/admin partners use the administrator's credentials;
other users sign in separately, and Copilot profiles cannot be shared through model grants.
External nanobot/Copilot token files are never imported: after upgrading, run
`deeptutor provider login github-copilot` again.

Login validates inference with a currently discovered model; `init` validates the selected
model and aborts on failure without saving the draft configuration. Successful GitHub
authentication alone does not establish Copilot model access (the saved login is retained
if validation fails). Runtime requests follow the API endpoint returned by token exchange,
including refreshes, and respect each model's Responses/Chat Completions endpoint metadata.

Copilot-specific Responses compatibility is applied at dispatch without rewriting stored history.

</details>

<details>
<summary><b>CLI-only distribution</b></summary>

The core wheel supplies CLI and SDK; `deeptutor-cli` is a compatibility metapackage. Source exposes all checked-in modules, so install their Python dependencies and skip frontend setup for CLI use:

```bash
python -m pip install -r requirements/full.txt
python -m pip install -e . --no-deps
```

For a minimal installation, use the core wheel. Optional distributions contribute tools, capabilities, API routes, background services, and navigation. Modules share one Python environment and must match the core version. `deeptutor[full]` selects the common app modules at installation; individual features can still be removed later.

Stop DeepTutor (`Ctrl+C` in its terminal), then use the same Python environment and `DEEPTUTOR_HOME`:

```bash
deeptutor module list                       # installed / enabled / ready
deeptutor module disable research           # hide and deactivate; keep code
deeptutor module enable research            # restore it and required modules

# Package installations only; source checkouts use enable / disable:
deeptutor module install solve              # install the matching module and dependencies
deeptutor module uninstall solve --dry-run  # inspect the plan and dependency blockers
deeptutor module uninstall solve            # remove only this module's distribution
deeptutor chat                              # restart the CLI; use start for an installed Web app
```

Examples: `solve`, `research`, `questions`, `knowledge`, `parsing`, `reading`, `mastery`, `books`, `memory`, `notebook`, and `partners`. Dependents block removal; core cannot be removed through the module command. Disabling or uninstalling preserves settings, conversations, knowledge bases, and generated files. Shared third-party dependencies are retained.

**In the browser:** **Settings → Runtime status → Modules** shows module status and the corresponding terminal commands. Package changes require a stopped environment and are performed in the CLI. **Chat → Customize page** and **Learning → New learning activity → Customize page** change personal page choices immediately; hiding an entry does not uninstall its module or revoke access.

The 1.7.0 package family uses matching versions across core and feature wheels. For local wheel installation, pass `--wheelhouse /path/to/wheels` to `module install`. See [module installation and source development](docs-for-dev/MODULES.md) for building the wheels and deployment details.

</details>

## 🧩 Ecosystem — EduHub & the Skills Community

DeepTutor skills use the open **Agent-Skills** format — a folder with a `SKILL.md` playbook (YAML frontmatter + Markdown) and optional reference files. Nothing about it is DeepTutor-specific, so any registry that speaks the format becomes a source for your library. DeepTutor ships with **[EduHub](https://eduhub.deeptutor.info/)** — our own education-focused skill registry — wired in as the default hub.

<details>
<summary><b>EduHub — DeepTutor's skill ecosystem</b></summary>

[**EduHub**](https://eduhub.deeptutor.info/) is the community hub DeepTutor launched for sharing teaching-oriented agent skills — Socratic tutors, flashcard builders, essay feedback, exam blueprints, concept explainers, and more. It is built into DeepTutor, so there's nothing to configure: a bare slug or an `eduhub:` prefix resolves to it.

**Find and install** — in the browser, open **Personalization → Skills → Import from EduHub** to browse the catalog and download a skill straight into your library. From the terminal:

```bash
deeptutor skill search "socratic tutor"               # search EduHub (the default hub)
deeptutor skill install socratic-tutor                # fetch → verify → register
deeptutor skill install eduhub:socratic-tutor@1.2.0   # pin a hub and a version
deeptutor skill list                                  # local skills with their hub provenance
```

**Publish your own** — package a `SKILL.md` and share it back to the community:

```bash
deeptutor skill login                                 # browser sign-in to EduHub
deeptutor skill publish ./my-skill                    # interactive: pick a track + tags, then upload
deeptutor skill update                                # roll back or release a new version
```

EduHub is also a standalone, ClawHub-compatible registry, so agents that aren't DeepTutor (Claude Code, Codex, …) can use it directly through the `eduhub` CLI — `npx eduhub install socratic-tutor`.

</details>

<details>
<summary><b>The import safety gate</b></summary>

Whatever the source, every import passes the **same safety gate** before anything touches your workspace:

- the registry's **security verdict** is checked first — flagged packages are refused unless you pass `--allow-unverified`;
- archives are extracted defensively with path-traversal, entry-count, size, compression-ratio, suffix, and symlink checks; executable bits are stripped, while extensionless files remain allowed;
- frontmatter is normalized to DeepTutor's schema and `always:` is **stripped**, so a downloaded skill can never force itself into every system prompt;
- provenance — hub, version, verdict, and install time — is written to `.hub-lock.json` for audits and updates.

In multi-user deployments, browser imports land in the authenticated caller's skill layer, while CLI and admin-console installs target the owner/admin workspace; admin skills stay hidden and read-only for ordinary users until granted.

</details>

<details>
<summary><b>Also compatible with ClawHub</b></summary>

Because DeepTutor speaks the open Agent-Skills format, **[ClawHub](https://clawhub.ai/)** works as a first-class source too — it's built in alongside EduHub. Pick it with the hub prefix:

```bash
deeptutor skill search "git release notes" --hub clawhub
deeptutor skill install clawhub:git-release-notes@1.0.1
deeptutor skill install clawhub:udiedrichsen/stock-analysis
```

When several publishers share the same slug, search shows each publisher and a
fully scoped install ref (`clawhub:<ownerHandle>/<slug>`).

Add more registries in `data/user/settings/skill_hubs.json`: a `type: "clawhub"` entry points at any compatible HTTP API (EduHub and ClawHub both speak it), `type: "command"` wraps whatever fetch CLI a registry ships, and `"default"` chooses the hub used for bare slugs. All of them feed the same import gate.
