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.
Local-first visual note-taking on an infinite canvas with mind maps and knowledge-base AI
Place cards anywhere on the canvas, then switch to mind-map or database views to see structure without reorganizing your notes.
Highlight and annotate PDFs on the canvas and take timestamped notes on videos; highlights automatically become reference cards.
Semantic search, knowledge-base Q&A, and content retrieval find the right notes; chat works with your own model API key.
Files live on your device by default and sync across devices through WebDAV, S3, OneDrive, or Baidu Netdisk — your credentials stay yours.
