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.
