What it does for you

Finally know if your AI app is succeeding

Without clear criteria, you can't tell if a new prompt does better or worse. This method helps you write numeric criteria, rejects vague wording and computes 7 metrics to say, criterion by criterion, whether each threshold is met.

  • Replace “it works well” with numeric thresholds
  • Get a met / not met report for each criterion
  • Block a version that falls below your thresholds
