About Cerebro
What Is Cerebro
Cerebro is a web app that collects the content you meant to read or watch, then makes it searchable. You paste a link or upload a PDF, and the platform indexes it in the background. Later you ask a plain question and get the answer plus the clip it came from.
The problem it targets is the tab graveyard. Most people save hundreds of videos, articles, and books and finish almost none of them. Cerebro reads in the background so you don't have to, and pulls out the parts that matter. The AI assistant inside the app is named Nova, and it handles the search, summaries, and connections between your sources.
The catch is scope. Cerebro works best as a tool for individual learners and researchers, not as a team wiki with permissions and shared workspaces. The knowledge graph is personal, so colleagues can't browse your Cerebro library, and the free tier caps how much you can process.
Getting Started
- Sign up at heycerebro.com and start the 3-day free trial.
- Add content by pasting a link to a YouTube video, podcast, or article, or uploading a PDF.
- Let Nova process the file; it extracts key points and builds connections on its own.
- Ask a question in the chat and read the answer with its source citation.
- Create notebooks to group related sources, then move to a paid plan when you hit the processing limit.
- Write in the built-in editor and use smart notes to jump back to the exact spot in a source.

Key features
Capture by Link or Upload
Adding content takes one step. Paste a YouTube, podcast, or article link, or drop in a PDF, and Cerebro turns it into searchable knowledge. It also acts as a video summarizer, returning the key points from a long clip without you watching it end to end. The platform says it handles videos, articles, books, and image-to-text extraction, so you're not stuck retyping a scanned document.
Nova, the AI Assistant
Nova is the assistant that does the work behind the scenes. It reads your sources, pulls out key points, and answers questions in plain language with the exact source attached. Because answers cite their origin, you can check a claim instead of trusting a summary blindly.
Connected Knowledge Graph
Every new item links to what you already saved. Cerebro calls these links neurons and shows patterns across your library, so related ideas surface even when they come from different formats. The graph grows with the library, which is why it rewards keeping one account rather than many.
Focused Writing and Research View
The editor strips the page down to the text in front of you. You take smart notes as you read or write, and each note remembers exactly where you made it, so one click jumps you back to that spot. Markdown formatting, word count, and an in-app dictionary sit in the same view.
Writing Feedback
As you type, Cerebro flags weak verbs, repeated words, and cluttered sentences. It's a light touch that nudges the draft toward cleaner prose without a full grammar-checker takeover. For people who write from research notes, that feedback lands while the source is still open.
Unlimited Notebooks
You can create as many notebooks as you like on every plan, even the free one, and sort sources by project, course, or topic. Grouping keeps a long library navigable, so a semester of lectures doesn't blend into one undifferentiated pile.
Plan-Based Processing Limits
The tiers differ mainly in how much content you can process. The free Learner plan covers up to 3,400 pages, 100 videos, and about 1 million words, plus limited chat. The Researcher plan lifts that to 8,400 pages, 200 videos, unlimited chat, and over 3.7 million words. Both tiers keep PDF to notes extraction and image-to-text working.
Pros and cons
Pros
- Turns long videos, articles, and PDFs into searchable notes without manual copying.
- Answers cite their source, so you can verify a claim before you rely on it.
- A free Learner plan and a 3-day trial make it cheap to test on real content.
- Unlimited notebooks on every tier keep a large library organized by project.
- Writing, notes, and search live in one view instead of across separate apps.
Cons
- No team features, so it can't serve as a shared wiki with permissions and collaborative editing.
- The free plan's chat is limited and its processing caps are modest, which pushes active users to pay.
- The knowledge graph is personal, so you can't browse or search a colleague's library.
- No public API is documented, which rules out custom integrations or automated pipelines.
