An infinite AI canvas that turns scattered ideas into finished plans
Notes, images, videos, links, colours, audio memos with transcription, and freehand drawing all live on one pan-and-zoom board.
The agent reads the whole board, not just the current note, so it can summarise a project, answer questions about it and write structured cards into your layout.
Jump straight into a video brief, app flow, website plan, storyboard, roadmap, moodboard, competitor research or weekly planner.
Embed lightweight interactive elements such as skill meters, status views and to-dos directly inside the canvas.

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.
