PromptAncestry AI

Prompt optimization & experimentation workspace

Every generation gets better.

Analyze, revise, test and version your AI prompts. AI suggestions are treated as hypotheses — only your own test runs count as proof.

Locked preferences

Pin the facts, prices and tone that must never change. Every AI revision is instructed to preserve them.

Explainable analysis

See specific observations about your prompt and three meaningfully different revisions — each an untested hypothesis.

Weighted rubrics

Define what “better” means to you. Edit criteria and weights, and compare candidates side by side.

Real test runs

Run variants on your own test cases with repeated trials, run caps and stop controls. Outputs are stored.

Immutable versions

Every version is preserved with its parent. Branch, revert and diff. Nothing is overwritten.

Honest labels

Measured data, manual scores and AI-judge opinions are always labeled separately. You promote winners — not the AI.

Our honesty rules

  • • We never show AI output unless it was actually generated for you.
  • • “Proven” is reserved for results from tests you ran.
  • • AI-judge scores are labeled subjective. We don’t claim statistical significance.
  • • A new winner is only set when you approve it.
