AI broke my app: how to go back to the last working version

AI FixControlled demo · fake data

Demo built and run 30 Sept 2026 · Published 1 Oct 2026 · Last reviewed 1 Oct 2026 · By Ctrl+Z Therapy (how we test)

The short answer

You can only go back to a version you saved. Before your next AI change, test what works now and save that version with a clear name, like "checkout works". Then ask for the change. If it breaks something, go straight back to the version you saved.

What to do

  1. Test what works now.
  2. Save that version and give it a clear name, like "checkout works".
  3. Ask for the change.
  4. If it breaks something, go straight back to the version you saved.

Good to know

  • Most tools call it version history, a checkpoint or a commit.
  • Restoring code doesn't always undo database changes.

How we checked it

We ran this in a demo app with fake data on 30 Sept 2026, and the video shows the result. Try it on your own app with test accounts and test data, never real users' data.
