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.

Notion Integration Setup — Help

Connect your Notion workspace to BrainTube to make your notes part of your knowledge corpus.

Connecting Notion

Go to Knowledge Hub → Connected Sources
Click "Connect Notion"
Authorize BrainTube to access your Notion workspace
Select which pages or databases to sync

What Gets Synced

Page titles and content
Database entries
Nested pages
Rich text formatting (converted to markdown)

Sync Behavior

Automatic sync — Changes in Notion propagate to BrainTube
Rate limited — 350ms between API calls to respect Notion's limits
Incremental — Only changed pages are re-synced
2-second delay between users — Prevents hitting global rate limits

Callback Setup

After authorizing, you'll be redirected back to BrainTube via the Notion callback page. If this fails, check that popups aren't blocked, try the connection again from Knowledge Hub, and make sure you're logged into the correct BrainTube account.

Tips

Start by syncing a few key pages to test
Notion databases with many entries work best as collections
The integration preserves your Notion structure
