In partnership with MB Academy
Developed further with MB Academy.
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.
Within MB Academy we developed Second Brain further: Mike’s course is inside your brain. Members use it for free.
Read how it works first; you can also request it at the bottom.
The course, from the inside.
Mike’s full course is inside your brain. Ask “what did Mike say about positioning” and you get the answer from the course, applied to your brand, your customer and what you already decided. The brain keeps the order of the lesson: first your customer, then your competitors, then the answer.
Today: answers from the course, applied to your brand. Coming soon: the brain walks you through the lesson step by step.
You ask; the brain applies the course to your brand.
Claude with Second Brain, next to Claude without.
