SurfSense

SurfSense is an open-source private research notebook that runs entirely on local machines without cloud storage or accounts.

SurfSense is an air-gapped, open-source research notebook designed for confidential work by lawyers, accountants, consultants, and engineers. It runs entirely on local machines as a desktop application for Windows, macOS, and Linux without requiring cloud storage, user accounts, or terminal setups. Users can connect local models via Ollama or bring their own API keys for providers like OpenAI and Anthropic. The software indexes documents locally to answer questions and generate deliverables such as slide decks, written reports, audio podcasts, spreadsheets, and quizzes. The index and generated artifacts are stored securely in a local database on the user's computer.
