Prompt Regression Lab
A lightweight testing suite for people shipping AI workflows. Users save representative prompts, expected traits, safety rules, and sample documents; the app reruns them whenever they change models, system prompts, tools, or retrieval settings, then highlights meaningful behavior drift. It is aimed at solo AI builders who currently discover broken prompts from customer complaints. Start with side-by-side outputs, human scoring, and simple pass/fail assertions before adding automated evaluators.
