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.
