PromptBench — A/B Testing Tracker for Prompt Variations

Why This is an Opportunity

It's a form + comparison dashboard. The audience (prompt engineers, AI consultants, content agencies) is vocal online and actively looking for workflow improvements.

Key Pain Points

  • Running the same prompt 5 different ways and losing track of which tweak made the output better
  • Spreadsheets with 47 columns trying to compare prompt performance across models
  • No structured way to document why you changed a prompt — just vibes and memory
  • Clients ask 'why did you pick this prompt?' and you can't show your work

Original Discovery

People who sell prompt packs or run AI workflows constantly test different prompt versions but track results in spreadsheets with columns like 'v3_final_FINAL_good'. PromptBench lets you log prompt variations side-by-side, paste in the outputs, rate them, and see which version wins over time. Dead simple comparison tool.
