open-notebookOrganizes research with the self-hosted Open Notebook alternative to NotebookLM.
Open Notebook is an agent skill from K-Dense-AI/scientific-agent-skills. Organizes research with the self-hosted Open Notebook alternative to NotebookLM. Supports source ingestion (PDFs, web pages, audio, video, and Office documents), cited document chat, text and vector search, notes, custom transformations, and multi-speaker podcasts. Use when automating Open Notebook through its REST API or configuring its local or cloud AI providers, including OpenAI, Anthropic, Google, Ollama, Groq, and Mistral.
Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including scripts and reference files (for example `references/api_reference.md`, `references/architecture.md` and `references/configuration.md`). Compatibility notes: Requires a running Open Notebook backend and worker; Python 3.11+ with requests for bundled helpers. Docker Compose is the documented deployment option…
It sits in AI & LLM Engineering, covering Vector databases, Source-grounded notebooks and Podcasting. It works with Mistral AI, NotebookLM, Ollama and OpenAI. The repository describes itself as: Turn any AI agent into an AI Scientist. The 1 Agent Skills library for science, used by 250,000+ scientists worldwide. 177 ready-to-use validated skills plus 100+ scientific… The licence is MIT.
Read from SKILL.md and the folder at commit 92ace75. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Ships 4 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
dockercurluvFrom the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
raw.githubusercontent.comAlso links to:
arxiv.orggithub.comdoi.orgexport.arxiv.orgFrom URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
OPEN_NOTEBOOK_ENCRYPTION_KEYOPEN_NOTEBOOK_PASSWORDSURREAL_PASSWORDFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Requires a running Open Notebook backend and worker; Python 3.11+ with requests for bundled helpers. Docker Compose is the documented deployment option. Network access to the instance and any configured providers is required.
From compatibility in the SKILL.md frontmatter.
Open Notebook loads about 2.8k tokens when it runs, and up to ~13k if it reads all its reference files. Until then it costs about 112 tokens; SKILL.md has 1,100 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

.claude/skills/open-notebook/SKILL.md (or your agent's skills folder). This skill also uses 8 other files; get the full folder from GitHub.Open Notebook organizes sources, notes, and AI conversations into research notebooks. It supports several AI providers through Esperanto, full-text and vector search, custom transformations, and podcast generation with speaker profiles. Application storage is self-hosted; content sent to configured cloud models is not local-only.
This skill targets the latest published release observed on 2026-09-30,
v1.14.0.
Request/response contracts were checked against its official source and current main
commit 3127f14ea9dbb519f0e4ddc64a0742ca644ba6ef. Bundled helpers have mocked HTTP
regression tests; deployment, ingestion, and paid AI calls were not run against a
live instance. Deployment and remote workflow examples are illustrative.
Use Docker Desktop/Engine with Compose. The upstream docker-compose file configures
SurrealDB v2 and the lfnovo/open_notebook:v1-latest application image. It mounts
./notebook_data at /app/data and ./surreal_data at /mydata.
curl --fail --location --output docker-compose.yml \
https://raw.githubusercontent.com/lfnovo/open-notebook/v1.14.0/docker-compose.ymlBefore starting, edit the downloaded Compose file: replace the literal
OPEN_NOTEBOOK_ENCRYPTION_KEY=change-me-to-a-secret-string value, or change it to
${OPEN_NOTEBOOK_ENCRYPTION_KEY:?Set OPEN_NOTEBOOK_ENCRYPTION_KEY} and supply that
variable. Exporting a shell variable alone does not replace the upstream literal.
Retain the key across restarts; it encrypts provider credentials, not source documents.
Set OPEN_NOTEBOOK_PASSWORD in the application's container environment when password
protection is wanted; clients then send Authorization: Bearer <instance-password>.
For a reproducible deployment, resolve and record an image digest; v1-latest moves.
docker compose up -d
docker compose logs --tail=100 open_notebookhttp://localhost:8502http://localhost:5055; API base: http://localhost:5055/api/docs, /redoc, /openapi.jsonSource installation is also supported; it needs a separate processing worker. See configuration for persistence and provider setup.
In Manage → Models, add a configuration/credential, test it, discover models,
and register the particular models needed. Assign chat and embedding defaults;
assign speech models separately for transcription/podcasts. OpenAI, Anthropic,
Google, Ollama, Groq, and Mistral have different modalities. Discover support from
the instance's /api/models/providers; do not infer speech support from LLM support.
Credential discovery returns discovered[] with name and provider, often without
a usable model_type. Registration requires models[] containing name, provider,
and an explicitly chosen model_type. The four types are language, embedding,
speech_to_text, and text_to_speech. They are not llm, stt, or tts.
See the API reference and
credential example.
Resolve this skill's directory and run from its scripts/ directory, or add that
directory to the Python import path. Install requests in a dedicated environment,
for example uv run --isolated --with requests python notebook_management.py --help.
Each CLI only lists records; creation, AI calls, and deletion are explicit functions.
Set OPEN_NOTEBOOK_URL to the backend origin (an existing /api suffix is also
accepted). Set OPEN_NOTEBOOK_PASSWORD only if the instance requires authentication.

ai_messages = [m for m in answer["messages"] if m["type"] == "ai"]Create a notebook with POST /api/notebooks and JSON name, description.
Use POST /api/notes with content, optional title, notebook_id, and
note_type="human" or "ai". A missing title on an AI note invokes a model.
Notebook deletion removes notes and chat sessions; source deletion is controlled by
delete_exclusive_sources. Inspect /delete-preview before intentional deletion.
POST /api/sources takes form fields, including required type: link, upload,
or text. Supply respectively url, multipart file, or content. Use notebooks
as a JSON-encoded list in form data. async_processing and embed both default to
false. The fields text and process_async do not implement these options.
Use /api/sources/json for JSON bodies; the form endpoint does not accept arbitrary JSON.
Wait for /api/sources/{id}/status; a failed job must not flow into analysis as if
it succeeded. Inspect full_text after extraction, especially for scanned PDFs,
tables, and transcripts. Vector retrieval additionally needs embed=true, a default
embedding model, and completed embeddings (embedded_chunks > 0). Source list pages
are limited to 100; use iter_sources for a stable collection. It defaults to a
1,000-page cap and raises on repeated IDs, malformed pages, or an exhausted cap.
Discard partial results after an error; raise max_pages explicitly if needed.
Call /api/chat/context with notebook_id and context_config, whose sources and
notes maps associate IDs with "full content", "insights" (sources), or
"not in context". An empty config includes all notebook items in short form;
explicit empty maps select nothing. Review returned items and token_count.
Send the returned context object to /api/chat/execute with session_id and
message. It returns JSON {session_id, messages}; message fields include type
(human/ai) and content. include_sources flags do not build context.
POST /api/search uses query, type="text" or "vector", limit (1–1000),
search_sources, search_notes, and minimum_score (0–1, vector only).
Read total_count, the returned-hit count rather than a corpus-wide total.
On v1.14.0 search and Ask are global; sending unsupported source_ids/note_ids
does not filter results. Main after v1.14.0 adds notebook scoping, but check the
installed OpenAPI schema before relying on it. Use selected-source chat when
scope must be guaranteed on the release API.
Ask requires question, strategy_model, answer_model, and final_answer_model
with registered model record IDs, plus an embedding model. /api/search/ask/simple
returns {answer, question}. /api/search/ask streams SSE, including error events.
Create transformations with name, title, description, prompt, and optional
apply_default/model_id. Execute with transformation_id, input_text, optional
model_id; read output. Treat generated findings as drafts and verify numerical
claims and citations against the extracted source.
Podcast generation requires episode_profile and speaker_profile names, an
episode_name, and explicit content or notebook_id. One speaker profile holds
multiple speakers. It returns a job_id; poll its job with a deadline, and read
result.episode_id on success before downloading episode audio. Review the script
for unsupported scientific claims before sharing it. See
worked examples.
OPEN_NOTEBOOK_ENCRYPTION_KEY belongs on the server; API clients do not need it.
SURREAL_PASSWORD (not SURREAL_PASS) configures the database password. Preserve
both database and /app/data, including uploads, podcasts, and SQLite chat state.
The backend uses FastAPI, SurrealDB, LangChain/LangGraph, and Esperanto; the UI uses
Next.js. Background jobs need the worker even when the API health check succeeds.
See architecture.
Self-hosting controls application storage. Configured cloud LLM, embedding, transcription, speech, and extraction services can receive research content. For local-only processing, configure every relevant stage locally; a local chat model alone is insufficient. Reconcile extraction completeness, context membership, retrieval coverage, and source citations before using outputs as scientific evidence.

Organizes research with the self-hosted Open Notebook alternative to NotebookLM. Open Notebook is an agent skill from K-Dense-AI/scientific-agent-skills. Organizes research with the self-hosted Open Notebook alternative to NotebookLM.
Open Notebook fits situations like: automating Open Notebook through its REST API; configuring its local; cloud AI providers; including OpenAI.
Run `npx skills add K-Dense-AI/scientific-agent-skills --skill open-notebook -a claude-code`. Or copy the skill folder (skills/open-notebook in K-Dense-AI/scientific-agent-skills) into .claude/skills/open-notebook in your project. Claude Code loads it when a task matches its description.
Run `npx skills add K-Dense-AI/scientific-agent-skills --skill open-notebook -a codex`. Or copy the skill folder (skills/open-notebook in K-Dense-AI/scientific-agent-skills) into .agents/skills/open-notebook in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add K-Dense-AI/scientific-agent-skills --skill open-notebook -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/open-notebook, .gemini/skills/open-notebook, .github/skills/open-notebook and .opencode/skills/open-notebook in your project.
Going by SKILL.md and its folder, Open Notebook needs Python for the scripts in its folder, the command-line tools its instructions call (docker, curl and uv) and credentials named OPEN_NOTEBOOK_ENCRYPTION_KEY, OPEN_NOTEBOOK_PASSWORD and SURREAL_PASSWORD. Our summary lists: Python 3; Docker; A credential in OPEN_NOTEBOOK_ENCRYPTION_KEY. Compatibility (from SKILL.md): Requires a running Open Notebook backend and worker; Python 3.11+ with requests for bundled helpers. Docker Compose is the documented deployment option. Network access to the instance and any configured providers is required..
SKILL.md names 5 domains. In commands or code: raw.githubusercontent.com; the agent is likely to contact it when it follows the instructions. As links in the text: arxiv.org, github.com, doi.org and export.arxiv.org. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Open Notebook is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.8k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 11k tokens, read only when the agent opens those files.
