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

The AI workspace where teams and agents get work done together
Combine docs, wikis, projects, and databases into one structured system of record that stays linked as your content grows.
Draft, summarize, translate, and answer questions inline, or build custom agents that automate recurring workflows around the clock.
Find answers instantly across Notion and connected apps, with citations so you can verify where each answer came from.
Use relations, rollups, views, and a large template gallery to model anything from a CRM to a content calendar.
