An experiment

Let AI build your app. Undo anything.

Tidemark records every change the AI makes — what you asked, what changed, and proof it works. Go back to any moment, with your data.

Go back to any moment. Your app and its data come back together.

Try changes on a copy. Your real app isn't touched until you keep it.

See what's live, who changed it, and why.
