Mike BuitenFounder of MB Academy
Second Brain is one of the first tools that has truly changed the way I work every day.

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.

What only members get

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.

MB Academy, lesson 9 · Research for your product nichecompleted 5 Sep
Find your ideal customer in the reviews: put screenshots of reviews on Amazon or Trustpilot into Claude. The biggest objection in those reviews is what your message has to answer.
MB Academy, lesson 13 · Positioning and brand identitycompleted 12 Sep
Look at what your competitors do well and what could be better, and position yourself on five points. If your top 5 all look the same, build on what works, with your own difference.
MB Academy, lesson 20 · Shopify, part 3completed 3 Oct
The product page: reviews, title, price, trust badges, variant picker, buy button, description. In the checkout, “Pay now” becomes “Complete your order”: people don’t like paying.
Your conversation · ideal customer14 Sep
Woman, 30 to 45, works full time. Wants one bag that lasts for years. Hesitates over: will the leather wear, and is sending it back a hassle?
Your conversation · October figures3 Nov
3,700 visitors, 41 orders (1.1%). 64% leave the product page without a click. 78% of traffic is mobile. Bestsellers: the Shopper, the Weekender and the Crossbody.
Your conversation · competitors21 Oct
Two competitors put their guarantee and reviews at the top. Neither shows the maker or the workshop.
Your conversation · material28 Oct
Full-grain leather, stitched by hand. Ten-year guarantee on the leather and the seams.
Your conversation · returns policy2 Oct
Free returns within 30 days. We collect the bag ourselves.
You don’t have a traffic problem, you have a trust problem: 64% of your visitors drop off on the product page. That’s where your customer wonders whether the leather will stay beautiful and whether sending it back is a hassle, and according to lesson 9, that biggest doubt is exactly what your message has to answer.
Your plan for this week
  1. Rewrite the first line.Not “Handmade leather shopper”, but the answer to her biggest doubt:
    The bag you’ll still be carrying in ten years. Full-grain leather, stitched by hand.
    Lesson 9 · your conversation of 14 Sep · your conversation of 28 Oct
  2. Three kinds of proof above the button.Your review score with the number of reviews, your guarantee in one line, and one photo of the maker at work. None of your competitors does that last one, so that’s your difference. Check it on your phone: that’s where 78% of your visitors are.Lessons 20 and 13 · competitors 21 Oct · October figures
  3. One line next to the pay button.Call that button “Complete your order” instead of “Pay now”, and take away her second doubt at the moment she feels it:
    Not quite right for you? Free returns within 30 days, and we collect it.
    Lesson 20, the checkout · your conversation of 14 Sep · your conversation of 2 Oct
What it’s worth:going from 1.1% to 1.5% means around 15 extra orders a month at your current traffic, without spending a single euro more on ads.
Which of your three bestsellers do you want to start with? Then we’ll write that page together, right now.
Example conversations, written from real situations. Names and amounts are invented.
