Turn videos, articles, and PDFs into searchable knowledge
Query your saved videos, articles, and documents naturally and get precise answers instead of scrolling through tabs and folders.
Every response points back to where the information came from, so you can check the original context before acting on it.
Paste a link or upload a PDF and Cerebro turns it into searchable knowledge without a manual note-taking ritual.
The assistant analyses content while you work and highlights the important passages so long videos and articles become actionable.
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.
