An intelligent notebook that turns browsing, files and video into notes
Collect web pages, PDFs, images, notes and sketches into a single space instead of juggling separate apps.
Your content is stored on your device with import and export options, and the core source is public on GitHub.
Connect cloud LLMs with your own API key or run local models, choosing the intelligence layer yourself.
Generated notes link directly back to the source page, video or document they came from.
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.
