Send to BigBrain by BigBrain

Capture the current page as clean markdown into your BigBrain vault's inbox.

Send to BigBrain captures the page you are reading as clean markdown and files it into your BigBrain vault - a personal knowledge base kept organized by an agent.

One click saves the page. Add an optional note in your own words. BigBrain's editor then files the capture, links it to the people, projects, and ideas it mentions, and keeps building those connections as you add more. A pile of clips becomes an organized, cross-linked vault - without you doing the filing.

• One-click capture: the full page as rendered, converted to clean markdown (works on SPAs and lazy-loaded pages)
• Notes in your voice: type a note when you save; the editor treats your words as instructions
• Automatic filing and linking: an agent organizes what you save, on its own time
• Sign in with Google — no configuration
• Nothing is captured until you click. The extension does not track your browsing.

BigBrain is in early access. Sign-ups are limited to invited users.
