“"Currently, Open Notebook requires internet access for certain operations." — maintainer issue #374, https://github.com/lfnovo/open-notebook/issues/374”
You know that feeling when your research, notes, and questions live inside a service that controls the models, hosting, and workflow? You may want to keep sensitive material on infrastructure you control, choose a cheaper or local AI model, and automate research tasks through an API. Open Notebook gives you that control in a NotebookLM-style interface. The trade-off is that you become responsible for deployment, model setup, updates, backups, and security.
Think of Open Notebook as a private research desk with a filing cabinet, an assistant, and a podcast booth. You add a PDF, web page, audio file, or other source; the backend extracts and splits the content, creates embeddings, finds topics, and stores everything in SurrealDB. When you search or ask a question, FastAPI retrieves relevant text and sends the task through Esperanto to your chosen hosted or local AI model. Next.js shows the results, while Surreal-Commands handles longer jobs in the background and LangGraph coordinates multi-step AI flows.
If you build or operate self-hosted AI tools and want a NotebookLM-style workspace with model choice, Open Notebook deserves a test. It also fits your workflow if privacy, API access, custom transformations, or local-model support matters more than zero-maintenance setup. It is not for you yet if you need verified air-gapped operation, a commercial support agreement, basic setup with no troubleshooting, or mature citations for research-sensitive work.
Yes, explore it as a self-hosted research workspace or internal proof of concept. The project shows active maintenance, 37 releases on the repository page, a June 2, 2026 release, and 48 contributors, but open air-gap work, known provider failures, basic citations, past high-severity security fixes, and mixed setup reports keep it in beta territory. Do not treat the "100% local" claim as verified until you test the exact workflow with external networking blocked.
