You ask. The brain finds. You carry on.
Second Brain is a memory for your work with AI. It saves your conversations in Claude Code and Codex and, when you ask something new, brings in the context on its own, with the source. It works on Mac and Windows, and in Claude Code on the web. It is for entrepreneurs who work with AI every day. It costs €19 per month, excluding VAT; MB Academy members currently use it for free, under the terms. You request your brain at second-brain.site.
Three things, and how it fits the way you work. Then you request your brain.
Three things. Nothing else.
Whether you use AI every day or ask the odd question, it works the same.
It saves
Every conversation in Claude Code or Codex goes to your own brain. Nothing else from your computer.
It finds
Ask a question and the brain looks up what goes with it: an agreement, a price, a decision from weeks ago.
It knows when
Bring in your existing chats. Every message keeps its original date, so the brain knows what you decided when.
The way you work.
Pick how you use AI today. The explanation adapts; the brain stays the same.
You no longer explain who someone is or what you decided last week. You ask your question the way you would ask a colleague.
Request your brain, connect and test it after approval, and bring in old chats if you want. After that, your brain saves new Claude Code and Codex conversations automatically.
