Developers

How it works

One loop. Mess in, prompt out, proof after.

  1. 01

    Compile

    A rant becomes Role, Tone, Audience, and a copy-ready prompt for the app you actually use.

  2. 02

    Prove

    Run A/B in Test Bench. Same model. See what the polished prompt changes.

  3. 03

    Remember

    Your stack stays on. The second generation already sounds like you.

Test Bench

Don't just copy it.
See if it works.

After Magic Polish, A/B your raw rant against the compiled prompt on the same model. Test Bench needs an account.
