Free and open source. No account with us, no subscription.
The fastest way to your own private memory layer, with nothing to manage.
No terminal, no technical steps. Choose a password, sign in to a free Cloudflare account, and the app does the rest.
Everything lives in your own Cloudflare account from day one. Nothing runs on our servers, and we cannot see what you store.
Claude, ChatGPT, Cursor, and any MCP tool draw from the same brain, so your context follows you everywhere.
The app updates itself, and can update your Second Brain in place, so you are always on the latest without lifting a finger.
Three steps, all inside the app.
Download for your computer above, open the app, and click Get started.
Pick a password and sign in to Cloudflare, or create a free account in the same window. The app builds your private Second Brain for you.
It wires up Claude Code and Cursor for you and gives you a link to paste into ChatGPT and Claude on the web. Then your dashboard opens, ready to use.
