What Evidently AI does
Evidently AI is an open-source framework for evaluating, testing and monitoring AI systems, including LLM applications, RAG pipelines, AI agents and predictive ML models. It is aimed at AI builders and ML teams who need systems to stay safe and reliable after updates. Automated evaluations measure output quality, safety and reliability, run inside a pipeline and produce shareable reports. Synthetic data generation creates edge-case and adversarial test inputs, while a live monitoring dashboard tracks drift, regressions and emerging risks. The LLM eval library covers hallucinations, PII detection, retrieval quality, toxicity and guideline adherence, with support for custom metrics. The framework is free under the Apache 2.0 license; paid plan prices are not published.
