Notion, Dropbox, Zapier, and Coursera use Braintrust to ship better AI.
Score every part of your RAG pipeline.
Find patterns without reading every span
Use Loop to synthesize a starting dataset and find patterns in your traces like hallucination or issues in the vector retrieval process without manually reading each span yourself.
20+ RAG scorers. Zero setup
Faithfulness, ContextPrecision, ContextRecall, AnswerRelevancy, and more via autoevals. Or write your own. No scorer infrastructure to build or maintain.
Production failures become RAG test cases
When a query returns a bad answer in production, tag it and it lands in your golden dataset. Your RAG testing suite grows from real failures.
