Full local Web app + CLI, no clone required. Needs Python 3.11–3.14 and a Node.js 20+ runtime on PATH (the packaged Next.js standalone server is spawned by deeptutor start).

mkdir -p my-deeptutor && cd my-deeptutor
pip install -U deeptutor
deeptutor init     # prompts for ports + LLM provider + optional embedding/search
deeptutor start    # starts backend + frontend; keep the terminal open

deeptutor init prompts for backend port (default 8001), frontend port (default 3782), LLM provider / base URL / API key / model, an optional embedding provider for Knowledge Base / RAG, and an optional search provider for Web Search.

After deeptutor start, open the frontend URL printed in the terminal — by default http://127.0.0.1:3782. Press Ctrl+C in that terminal to stop both backend and frontend. Skipping deeptutor init is fine for a quick trial; the app boots with default ports and empty model settings, configure them later in Settings → Providers and Language models.

Browser microphone transcription: OpenAI-compatible STT adapters forward browser audio to the provider without local conversion. The native DashScope and Volcengine STT adapters convert browser WebM/Opus to 16 kHz WAV and require an ffmpeg executable on DeepTutor's PATH. A canonical 16 kHz mono PCM WAV bypasses this conversion. For Windows PyPI installations using either native adapter, install FFmpeg, add its bin directory to the service's PATH, then restart DeepTutor. Conversion failures appear below the chat input.

For development against a checkout. Use Python 3.11–3.14 and Node.js 22 LTS to match CI and Docker.

One container for the full Web app. Images on GitHub Container Registry:

• ghcr.io/hkuds/deeptutor:latest — latest stable release
• ghcr.io/hkuds/deeptutor: — exact release without the leading v (for example :1.6.3); pre-releases receive only their version tag

See CONTAINERIZATION.md for podman/rootless/read-only-rootfs deployments and the full per-installation guide.

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

To choose a host content folder at container startup, mount it at the stable container path and lock DeepTutor to that path:

mkdir -p "$PWD/deeptutor-workspace/outputs"
docker run --rm --name deeptutor \
  -p 127.0.0.1:3782:3782 \
  -v deeptutor-data:/app/data \
  -v "$PWD/deeptutor-workspace:/workspace" \
  -e DEEPTUTOR_WORKSPACE_ROOT=/workspace \
  -e DEEPTUTOR_WORKSPACE_ALLOWED_ROOTS=/workspace \
  ghcr.io/hkuds/deeptutor:latest

For Compose, set DEEPTUTOR_WORKSPACE_HOST=/absolute/host/folder before running python scripts/docker_compose.py up -d. When omitted it uses ./data/user/workspace. Docker paths are selected at startup and therefore appear locked in the Web settings page.

Only 3782 needs to be published. The browser talks exclusively to the frontend origin; the Next.js middleware (web/proxy.ts) forwards /api/ and /ws/ to the FastAPI backend inside the container. Publishing 8001 (-p 127.0.0.1:8001:8001) is optional — handy only for hitting the API directly with curl or scripts.

Open http://127.0.0.1:3782. The container creates /app/data/user/settings/*.json on first boot; configure model providers from the Web Settings page. Config, API keys, logs, the default Content Workspace, memory, and knowledge bases persist in the deeptutor-data volume. A separately mounted Content Workspace persists at its host path instead. Optional extras belong on the deployment, not in a shell: set DEEPTUTOR_EXTRAS (and DEEPTUTOR_APT_PACKAGES for system libraries) and every container started from it re-applies them, where a docker exec … pip install would be lost at the next compose down.

• Different host ports: change the left side of each -p host:container mapping (e.g. -p 127.0.0.1:8088:3782). If you change container-side ports in /app/data/user/settings/system.json, restart and update the right side of each mapping to match.
• Detached: add -d, then docker logs -f deeptutor to follow, docker stop deeptutor to stop, docker rm deeptutor before reusing the name. The deeptutor-data volume keeps private runtime data and the default Content Workspace across restarts; a separately mounted Content Workspace persists at its host path.

{
  "next_public_api_base": "http://backend:8001"
}

next_public_api_base_external (and its alias public_api_base) are accepted as lower-precedence fallbacks. CORS uses frontend origins, not API URLs. With auth disabled, DeepTutor permits normal HTTP/HTTPS browser origins by default. With auth enabled, add exact frontend origins:

{
  "cors_origins": ["https://deeptutor.example.com"]
}

docker run --rm --name deeptutor \
  -p 127.0.0.1:3782:3782 -p 127.0.0.1:8001:8001 \
  --add-host=host.docker.internal:host-gateway \

When you don't need the Web UI. The CLI-only package is installed from a source checkout, not from PyPI.

git clone https://github.com/HKUDS/DeepTutor.git
cd DeepTutor
Create a venv (macOS/Linux). Windows PowerShell:
  py -3.11 -m venv .venv-cli ; .\.venv-cli\Scripts\Activate.ps1

python -m pip install -e ./packaging/deeptutor-cli
deeptutor init --cli
deeptutor chat

deeptutor init --cli shares the same data/user/settings/ layout as the full app but skips the backend/frontend port prompts. It still offers the Embedding and Search selectors (choose Skip when you do not need them), writes the key runtime files (system.json, auth.json, integrations.json, interface.json, model_catalog.json, main.yaml, agents.yaml), and prompts for the active LLM provider and model.

The local deeptutor-cli install ships no Web assets or server dependencies. Keep the source checkout around — the editable install points to it. To add the Web app later, install the PyPI package (Option 1) and run deeptutor init + deeptutor start from the same workspace.

The built-in office skills — docx / pdf / pptx / xlsx — work by having the model write a short Python script (python-docx, reportlab, openpyxl, …), run it through the single exec tool, and present the saved workspace file. Those tools mount whenever a sandbox backend is active. DeepTutor selects the strongest configured backend in this order:

• Runner sidecar: DEEPTUTOR_SANDBOX_RUNNER_URL routes execution to the

• Linux bubblewrap: when available, bwrap isolates the process and files.
• Restricted subprocess fallback: local and single-container installs use

The sandbox_allow_subprocess setting in data/user/settings/system.json (default true) controls only the last fallback. Set it to false (or export DEEPTUTOR_SANDBOX_ALLOW_SUBPROCESS=0) to refuse subprocess execution when no runner or bwrap backend is available; it does not disable those stronger backends.

Everything under data/user/settings/ is plain JSON/YAML. The Settings page is the recommended editor; workspace registrations live separately in data/user/.runtime/workspaces.sqlite3.

| File | Purpose | |:---|:---| | model_catalog.json | Provider connections plus LLM, task, embedding, search, TTS, STT, image, and video profiles, credentials, and active selections | | system.json | Backend/frontend ports, public API base, CORS, SSL verification, attachment directory and upload/extraction limits | | auth.json | Optional auth toggle, username, password hash, token/cookie settings | | integrations.json | Optional PocketBase and sidecar integration settings | | interface.json | UI and model output language / theme / sidebar preferences | | document_parsing.json | Parsing engine and image-description model selection, remote endpoints, and engine-specific options | | video_learning.json | YouTube caption provider, Invidious origins and account access, and transcript settings | | main.yaml | Runtime behavior defaults and path injection | | agents.yaml | Capability/tool temperature and token settings |

Web Search references are filtered by default: only public http/https URLs without embedded credentials or unusual ports are surfaced. Deployments can add an education-focused domain policy in data/user/settings/system.json:

{
  "web_search_source_filtering": {
    "enabled": true,
    "blocked_domains": ["spam.example"],
    "trusted_domains": ["edu.cn", "arxiv.org"]
  }
}

When trusted_domains is non-empty, references are limited to those domains and their subdomains; blocked_domains always takes precedence.

Project-root .env is not read as an application config file. For a minimal model setup, save a Base URL and API key in Settings → Providers, then add and select an LLM in Language models. Add an embedding profile only if you plan to use Knowledge Base / RAG features.

For API Route, select API Route in Settings → Providers and enter an API Route key. The preset uses https://global.api-route.com/v1; then add a model using its API Route model ID in Language models. See the API Route quickstart for key and model setup.

LLM and task-model profiles expose an API format setting when their provider supports a choice. Keep Auto for normal routing and fallback, or choose OpenAI Chat Completions, OpenAI Responses, or Anthropic Messages; forced Responses remains fail-closed. The persisted field is api_format (auto, openai_chat, openai_responses, or anthropic); wire_api is derived compatibility state. Per-model Auto / Supported / Not supported overrides cover tool calling, image input, JSON output, and reasoning controls.

DeepTutor separates its installed code, private runtime home, and optional Content Workspace. By default, the runtime home is the directory where you run deeptutor init / deeptutor start; --home PATH or DEEPTUTOR_HOME overrides it. Private application state is the data directory inside that home, so the startup banner line beginning with Workspace: identifies that runtime location. If Settings → Workspace points to another folder, back up or remove that content folder separately; it is intentionally not erased by uninstalling DeepTutor.

1. Stop the app. Press Ctrl+C in the terminal running deeptutor start, or
