Flexnote

Local-first visual note-taking on an infinite canvas with mind maps and knowledge-base AI

Infinite canvas with mind maps

Place cards anywhere on the canvas, then switch to mind-map or database views to see structure without reorganizing your notes.

PDF and video annotation

Highlight and annotate PDFs on the canvas and take timestamped notes on videos; highlights automatically become reference cards.

Knowledge-base AI

Semantic search, knowledge-base Q&A, and content retrieval find the right notes; chat works with your own model API key.

Local-first with your own cloud

Files live on your device by default and sync across devices through WebDAV, S3, OneDrive, or Baidu Netdisk — your credentials stay yours.

Strengths & Pros

+Local-first storage means notes stay on your device and work offline
+Combines infinite canvas, mind maps, and databases instead of splitting tools
+PDF and video annotation with automatic reference cards is rare in note apps
+Sync uses your own WebDAV, S3, or OneDrive accounts, so you keep control of data
