About
Evidently AI is an open-source platform for testing, evaluating, and monitoring AI applications including LLMs, RAG pipelines, and multi-agent workflows. It provides 100+ built-in metrics covering hallucinations, data drift, PII leaks, and custom evaluations. Teams can use it to ensure AI systems are reliable and production-ready across every update.
Problem
AI systems fail in non-deterministic ways—hallucinations, data drift, jailbreaks, PII leaks—that traditional software testing cannot catch.
For
ML engineers and AI teams building production AI applications
How it works
Users integrate the open-source Evidently library or platform to run evaluations and monitor AI outputs using 100+ built-in metrics, custom prompts, classifiers, and rule-based checks.
