Cerebro

Cerebro is an AI search tool that turns videos, articles and PDFs into searchable, connected knowledge. Cerebro turns videos, articles, books and PDFs into a searchable knowledge base and lets you ask natural language questions about them through its AI assistant, Nova.

Cerebro is a knowledge management workspace built around a simple premise: most of what you read, watch and listen to is lost shortly after you finish it. The product takes videos, articles, books and PDFs, converts them into a searchable library, and lets you interrogate that library in plain language. Its AI assistant, Nova, answers questions about your saved material and points back to the exact sources, so a two hour podcast with one useful segment no longer requires scrubbing through the timeline. In practice the workflow is deliberately light. You paste a link or upload a document, Cerebro extracts the key points, and the material joins a growing knowledge network where related ideas from separate sources link together. The notebook layer, organized around the PARA method (projects, areas, resources, archives), gives that material a home and a writing surface. The stated audience is broad: students working through lecture notes and papers, teachers structuring lesson plans, marketers tracking industry material, developers keeping documentation and snippets, journalists sifting interviews, and founders juggling everything at once. Where does it sit among alternatives? The comparison the site invites is with general note tools such as Notion. Cerebro's pitch is that notes alone still leave you searching, whereas an AI layer over your saved content lets you ask rather than dig. That puts it closer to research and reading assistants than to pure note taking, though the notebook and PARA structure mean it wants to be your primary information home rather than a sidecar. Buyers should treat it as a second brain for consumed content, not a project management suite. A few caveats are worth stating plainly. The homepage is long on outcomes and short on mechanics: there is no published detail on storage limits, how many sources a query can draw on, supported file types beyond articles and PDFs, or the accuracy of extracted key points. Pricing is not shown on the page at all, so cost has to be checked directly. There are free tools offered as a separate product surface, but whether a full trial of the main app exists is not stated. Readers who need audit level citations, enterprise controls or offline access should verify those before committing.
