Prompt Optimizer

Give your prompts a feedback loop. Generate, evaluate, rewrite, and compare the results across iterations.

What’s the idea?

Prompt Optimizer is a web app for refining AI prompts against an objective. You supply test cases and evaluation criteria, choose generation and evaluation models through OpenRouter, then follow how the prompt and its scores change over successive rounds.

What you can explore

  • Define test inputs and questions for an AI evaluator.
  • Run repeated generation, evaluation, and rewriting cycles.
  • Compare outputs and track prompt history against your criteria.
