Prompt QA for production teams
Audit prompts before they break in production.
Score prompts across clarity, context, robustness, cost, and safety. Flag critical issues, get concrete fix recommendations, and turn prompt quality into a repeatable discipline.
CTA is wired to a live pay link.
Weighted scorecard
Score prompts across clarity, context, robustness, cost, and safety instead of relying on gut feel.
Critical issue flags
Catch missing output formats, weak boundaries, and automation risks before they hit production.
Concrete fixes
Turn weak prompts into usable ones with immediate recommendations instead of vague critique.
Fast buying shortcut
If a real prompt just scored weak, do not leave with only a score.
Use the free evaluator for proof, then choose the smallest paid next step that fixes the prompt workflow you actually run: the one-time Founder Pack for immediate templates, or Pro when prompt QA is already a weekly habit.
