Finally understand the app you built.
You made something real with AI — even the parts you don't fully get. Explain My Build reads your own app and writes two plain guides: one to run it yourself, one for your users. And every line is backed by your real code, not a guess.
Point it at your app. Press one button.
No setup, no jargon, no command line. If you can pick a folder and press a button, you can run it.
Point it at your app
Open it and pick the folder your app lives in. In about two seconds it tells you what your app is — free, no AI needed for that step.
Press one button
Press "Make my guides." It reads your code and your build history, in plain words the whole way. If your app is running, it can also watch it work and check it for risks.
Read and approve
Out come two guides — a private runbook for you and a users' guide for them — plus a short video plan. Read them and press Approve when they look right.
Share or export
Share a link with an access code, or export a portable file you can keep. That's it.
Two guides from one look at your app.
🔧 A private founder runbook
How to operate, extend, and safely change the app you built — including the parts the AI wrote that you don't fully understand yet. Written for you, in plain words, so you can change one thing without breaking another. Free.
📘 A public users' guide
A clear guide that walks the people who use your app through how to actually do things in it. Hand it to your customers so you stop answering the same questions — and they stop getting stuck.
🎬 A short video plan
A simple plan for a quick walkthrough video to go with the users' guide — so you can show people how things work, not just tell them. All from one look at your app.
It cites. It doesn't guess.
Most tools that "explain your AI code" just guess and hope. This one is built to be honest about what it knows.
It never makes things up
Every claim in your guides points back to something real in your app — a file, a screen, or a step it watched happen. If it can't back a claim up, it leaves it out instead of inventing it.
It tells you how sure it is
On every claim it shows its confidence in plain words, from "Very sure" down to "Best guess." You always know what to lean on and what to double-check.
Your code never leaves your machine
Everything runs locally, right on your own computer. Nothing is uploaded anywhere — so it's safe to use even on apps that handle sensitive data like health records.
See a real guide it made.
A genuine users' guide, generated from a real demo app's code — nothing hand-written.
For founders who built something real with AI.
For non-technical and semi-technical founders who built a real app with AI and either don't fully understand it, or need to teach their customers how to use it. It is not a "learn to code" tool. If you can pick a folder and press a button, you can run it.

Good questions.
Is my code uploaded anywhere?
No. Everything runs on your own computer and your code is never sent anywhere. That makes it safe to use even on apps that handle health data.
What apps does it work on?
Apps you built with AI tools like Lovable, Cursor, v0, Bolt, Replit, or Claude. You just point it at the folder your app lives in.
Do I need to know how to code?
No. If you can pick a folder and press one button, you can run it. It explains each step in plain words as it goes.
How is this different from other "explain my AI code" tools?
Most of them guess. This one cites. Every line points back to real evidence in your app, it tells you how sure it is, and it leaves out anything it can't back up.
What do I actually get?
Two guides from one look at your app: a private runbook for running and safely changing it yourself, and a public users' guide for your customers — plus a short video plan to go with it.
How much does it cost?
The founder runbook is free. The users' guide, sharing by link and access code, and portable export are the paid layer, billed monthly.
