Overview

Chatter is a platform for building, evaluating and versioning LLM deployments. You assemble chains with function calling, Jinja2 templating, routing and RAG over a vector DB or other source, then run a test suite using LLM-based evaluation, semantic similarity and regex matching. Calls are logged with token, cost and latency analytics, and chains can be exported to code via an SDK.

Best for: Teams building LLM prompts and chains who need shared testing, evaluation and versioning.
Pricing: No prices are shown in the captured text; the site links to a pricing page and an enterprise contact route, and offers a free playground trial.

Strengths and trade-offs

Strengths

Automatic evaluation across roughly a dozen metrics
Separate viewer so non-technical staff can review
SDK and code export keep prompts out of the codebase
Per-call analytics on latency, tokens and cost

Trade-offs

No pricing figures shown on the captured pages
Site copy is dated 2023, so currency is unclear
No models, providers or vector databases named
Test and Share sections repeat the same copy
