Find the damage on a sample project, restore what you can, and prove it came back.
KB Cafe is a free AI knowledge base for developers. Its hands-on labs teach you to recover when AI damages something and verify when AI says something works, right in your browser.
Each lab runs in your browser on sample data, with no signup.
