⚡ AUTO-CREATES EVALS: Automatically builds evals to match user feedback & your prompt—no endless prompt refinement 🔍 ACCURATE & CONSISTENT: Unlike variable LLM-as-judge Integrate with Sheets, PromptFoo, GRPO & more or export as code Free tier: 25M tokens

Pi Copilot is an AI tool designed to quickly create deterministic evaluations, eliminating the need for endless prompt refinement. It automatically generates evaluations based on user feedback and prompts, ensuring accuracy and consistency compared to variable LLM-as-judge methods. The tool integrates seamlessly with platforms like Sheets, PromptFoo, and GRPO, and allows exporting evaluations as code. Its standout feature, Pi Scorer, outperforms models like Deepseek and GPT-4.1 in accuracy while operating at the speed and size of smaller models like GPT Mini and Gemini Flash. It can score over 20 custom dimensions in under 100 milliseconds, making it both highly efficient and precise. A free tier offers 25M tokens for users to explore its capabilities.
