Yes. Brainio is completely free with no document limits, no paywalls, and no hidden fees. We removed the paid plan entirely.

We rebuilt Brainio from the ground up. All your documents and data carry over automatically. The new version uses email and password for sign-in (not username), with Google sign-in support. If you had the old desktop app, you’ll need to uninstall it and download the new version. Everything else works as before.

Since Brainio is now completely free, we’ve disabled auto-renewal on all existing subscriptions. If you were on a monthly or yearly plan, no further charges will be made. You don’t need to do anything.

Indentation is the core of how Brainio structures your mind map. Press Tab to indent a line and make it a child node. Press Shift+Tab to outdent. Press Shift+Enter to add a new line within the same node without creating a new branch. The deeper you indent, the deeper the branch in your mind map.

Markdown is a simple way to format text using symbols like # for headings, ** for bold, and - for lists. You don’t need to know Markdown to use Brainio. Just write normally and use the toolbar to format your notes.

Share any document by inviting people via email. Set permissions to Owner, Editor, or Viewer. Everyone sees live cursors and changes sync instantly. You can also share a public read-only link with anyone.

Yes. You can export your documents as PNG, PDF, Markdown, or plain text. Your data is never locked in.

MCP (Model Context Protocol) lets AI assistants like Claude, ChatGPT, or Cursor connect to your Brainio notes. Your AI can read, search, and edit your documents directly.

Yes. Your data is encrypted in transit, we never sell your information, and we don’t show ads. Read our Privacy Policy for full details.
