A studio for your mind: object-based notes that stay connected
Model people, books, projects and meetings as typed objects with their own properties, instead of forcing them into folders.
See every link to a note at a glance, and let Capacities surface unlinked mentions where you already wrote about the same thing.
Capture thoughts without deciding where they belong first, then link and refine them later.
On paid plans, an AI assistant works alongside your notes, and image, PDF and weblink analysis turns outside material into usable content.
The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
