Save once. Query anywhere. BrainTube is your YouTube library, in the AI tools you already use: save anything you watch, read or say, then find it, ask about it and remember it, in the app or from Claude, Cursor and other MCP clients.

SAVE FROM ANYWHERE
• Tap Share in YouTube, Chrome or any app and choose BrainTube.
• Save voice memos and recordings: BrainTube transcribes them for you.
• Save PDFs and screenshots: the text is read and summarised.
• Paste a link straight into the app.

UNDERSTAND IT IN SECONDS
• Every save gets a core idea, key takeaways, a summary and the concepts it covers.
• Read the full transcript or text whenever you need the detail.
• "Ask about this" answers your questions about a single video or article.

FIND ANYTHING
• Search as you type across titles, channels, tags, summaries, highlights and concepts.
• Deep search finds passages that mean the same thing, even when the words differ.

CHAT WITH YOUR BRAIN
• Ask questions and get answers built from what you saved, with numbered links back to every source.

REMEMBER WHAT MATTERS
• Recall turns your saves into flashcards and schedules reviews with spaced repetition (FSRS), so ideas stick.

AND MORE
• Knowledge pods, map, wiki, skill tree, briefing, Content Lab, courses and imports from the BrainTube web app, signed in as you.
• Your library syncs with brain-tube.com, the browser extension and the iOS app.

Search is free. Chat is free up to a daily allowance (50 chats a day on Free, 200 on Starter, 1,000 on Pro), then uses credits. Deep search and "Ask about this" use credits from your BrainTube plan.
