SurfSense

A private, offline notebook that turns your own sources into reports, decks and briefings

Air-gapped, self-hosted operation

Install a normal desktop app on Windows, macOS or Linux and run it with no account. With a local model you can pull the network cable and keep querying your indexed sources, since nothing is sent to a vendor.

Bring your own model, or run a local one

Choose a bundled local Qwen or Gemma model at first launch, or paste a key for OpenAI, Anthropic or any OpenAI-compatible endpoint. The model is a setting rather than a fixed vendor choice.

Twelve artifact formats

Turn one set of sources into slide decks, reports, briefing notes, podcasts, mind maps, flashcards, quizzes, Markdown, Word, PDF, HTML and spreadsheet outputs — generated and stored locally.

Scraper plugins for live sources

Optional plugins pull research from Google Search, Reddit, YouTube, Instagram, TikTok, Google Maps, Amazon, Walmart, Indeed and the open web, and anyone can register their own MCP server.

Strengths & Pros

+Runs fully offline with a local model, so sensitive sources never leave your machine
+No account, no sign-up and no usage cap on the core application
+Choice of model — bundled local models or your own OpenAI, Anthropic or compatible key
