What is Ctrl+Z Therapy?

Ctrl+Z Therapy is a free clinic and YouTube channel for apps built with AI tools like Lovable, Bolt, Cursor and Replit. We rebuild the bugs that most often break these apps as controlled demos with fake data, show how to fix each one, and run the same request again to prove the fix. Send in your own app and we'll diagnose it and help fix it for free. Launched in September 2026. How we test.

How a session works

1 · Symptoms

You tell us what you see.

In plain words. A screenshot helps. No repo needed to start.

2 · Diagnosis

We find the cause.

And tell you how serious it is, without jargon.

3 · Treatment

We fix it with you.

Or give you exact steps to paste into your AI tool.

4 · Check-up

We prove it's fixed.

Same request, run again. It should fail where it used to work.
