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.
