How do I save my first item?

Paste any YouTube URL, article, or PDF into the capture bar. BrainTube extracts the transcript, generates a summary, and indexes everything within a minute.

How do I connect BrainTube to Claude or Cursor?

Open /connect in the app to get your MCP URL and API key, then paste it into Claude Desktop's config or Cursor's MCP settings. Your library becomes a tool the AI can call.

A Brain is a focused group of items you can chat with. Dashboard → Brains → New, pick items, give it a name. You can keep it private or share it publicly via a slug.

How does billing work?

Plans run monthly or annually with a 7-day trial. BrainTokens cover AI usage on top of your plan. Refunds within 14 days, no questions asked.

Where is my data stored?

EU-region infrastructure. You own your data, you can export it as JSON anytime, and account deletion purges backups within 30 days.
