Cerebro
Cerebro is a knowledge management platform that turns videos, articles, books, and PDFs into searchable insight you can actually use. Paste a link or upload a document, and the platform processes it so you can ask questions in plain English and get answers tied to your sources.
At the center is Nova, Cerebro's AI assistant. Nova extracts key points, summarizes content, and surfaces connections across everything in your library. The built-in notebook follows the PARA method for organizing notes, with markdown formatting, inline dictionary lookups, and anchored notes that jump back to exact spots in long documents.
Cerebro is built for researchers, students, and anyone sitting on a pile of podcasts, YouTube videos, and articles they never revisit. Free tools like Cerebro Assistant (a browser-accessible mini version) and Free Brain (a keyword-connected knowledge network) sit alongside the main library product.

What exactly does Cerebro do?
Cerebro ingests videos, articles, PDFs, and other content you save, analyzes them with its AI assistant Nova, and lets you ask natural-language questions to retrieve precise answers with sources.
How is Cerebro different from note-taking apps?
Unlike standard note apps, Cerebro automatically processes linked content, extracts key insights, and connects ideas across your library. It includes PARA-method organization and AI Q&A over everything you have saved.
Is my content secure?
Cerebro's privacy policy states it does not share personal information with third parties. Session data is collected through PostHog and Google Analytics to improve the app.
What are Neurons and how do they work?
Neurons are Cerebro's usage credits for processing content. Unused Neurons roll over to the next billing period according to the pricing page.
Does Cerebro offer a free trial?
Yes. The Learner plan includes a 3-day free trial before billing starts at $9.99 per month. Promo code LEARN50 gives 50% off the first month.
