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.

Saving Web Articles and Pages — Help

Save any webpage to your knowledge corpus with one click.

How It Works

Navigate to any article or webpage
Click the BrainTube extension icon
Click "Save to BrainTube"

BrainTube uses smart content extraction to grab the article body, stripping out ads, navigation, and other noise.

What Gets Extracted

Article text — The main content body
Title and author — Metadata from the page
Featured image — The main image, if available
Publish date — When the article was published
AI summary — Automatic summary generation
Key entities — People, concepts, and tools mentioned

Supported Content

The extension works great with:

Blog posts (Medium, Substack, WordPress, etc.)
News articles
Documentation pages
Research papers (HTML versions)
Forum posts and discussions

Tips

For PDFs, save the URL directly — BrainTube handles PDF extraction
Paywalled content — The extension can save content you have access to in your browser
Long-form content — There's no length limit; long articles are fully supported

Troubleshooting

Content looks wrong — Some sites use complex JavaScript rendering that may affect extraction. Try the "Paste URL" method in BrainTube instead.
Missing images — Article images are referenced by URL; if the original site removes them, they won't display.
