Hi Product Hunt! 👋

We launched PromptProof here in April to bring statistical rigor to prompt testing — confidence intervals instead of "it looks better."

Today we're launching Auto-Refine: instead of hand-tuning prompts and re-running experiments yourself, you point it at your labeled dataset, set a cost cap, and it searches for better prompts automatically. You get the top 3 candidates ranked by accuracy and cost, with the stats to prove the improvement is real.

It works across OpenAI, Anthropic, Google, and open models (via Together AI), and handles free-text outputs too, not just structured extraction.

Would love your feedback — especially on what trade-offs you'd want to control (accuracy vs. cost vs. latency).
