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.
