What your app is as a product, how it makes money, who it competes with and who it's for.
How to Think Through an App(so you can build it with AI)
Martín Silva Molina Second edition · 2026
AI already knows how to code. What it doesn't know is the app you have in your head. This book teaches you to think it through end to end —the product, the paper, the screens, the data— so AI can build it right.

Three parts, one example app
The whole book thinks through a real app, Falta Uno: booking a five-a-side pitch and filling the team when someone drops out. You'll work it out with Nico, who organizes the game, Fede, who comes to fill in, and Laura, who runs the venue.

Questions
Do I need to know how to code?
No. This book is about thinking the app through before AI builds it. If you do code, it's even more useful: it's the part almost nobody does.
Does it come with the courses?
No, it's sold separately. €10, once.
Can I download it?
No. You read it online, in your account, on any device, with your highlights and post-its.
Is it in English?
Yes. The English edition was written for English speakers, not translated word for word.
