Chatter
LLM testing platform
Chatter is a platform for building, evaluating, and versioning LLM deployments. It centralizes chain construction, prompt versioning, testing, and observability so teams can iterate on models and compare results across runs.
Core capabilities include a chain builder with function calling, routing, and Jinja2 templating; a testing suite with evaluation metrics such as LLM-based evaluation, semantic similarity, and regex matching; RAG pipeline setup with document repositories; an API key vault; analytics and per-call observability; a function builder; chat testing with multiple roles; SDK and code export; and a non-technical viewer for collaboration.
Chatter is aimed at teams building LLM products, including both technical and non-technical stakeholders. It is packaged in Pro and Enterprise editions, both with a fixed monthly rate and unlimited usage; Enterprise adds role-based permissions, on-premises hosting, custom integrations, and support options. A free playground is available for trying the product.
