Context A/B Tester

See how the information you give an AI changes its answer. Ask with your document, or without.

Ask one model one question two ways, side by side. Answer it cold, then answer it again with your document pasted in, and watch the answer become correct. Or compare two documents on the same question. Your own key, about a minute, free, no signup. Keys never leave your machine.

This free tool is a slice of the full product. With a paid plan you also get:

  • score which answer is actually grounded in your document
  • see which part of your setup caused a weak answer
  • search a whole library of documents, not just one you paste
  • handle thousands of documents at once
  • track changes over time

Free tool, provided as-is, no warranty. Uses your own API key. You are responsible for your usage and costs. Keys never leave your machine and are never sent to pysolvr. Outputs are informational, not advice. pysolvr is not liable for decisions made from these results.
