What is Respan (formerly Keywords AI)?

Respan is an LLM engineering platform for teams shipping production AI agents and applications. Route model traffic through one gateway, trace every call in detail, run evals on offline datasets and live traffic, and monitor cost, latency, and errors from a single dashboard.

The product grew out of Keywords AI, a Y Combinator Winter 2024 company founded by engineers from the University of Illinois. What started as LLM routing expanded into full observability after customers asked for visibility into how agents behaved in production. Respan now positions itself around the loop from tracing to evaluation to iteration.

It fits ML engineers, platform teams, and AI product builders who need gateway failover, prompt version testing, production quality scoring, and spend controls without stitching together separate tools. Customers cited on the site include teams at Retell AI, Mem0, Lovable, and Gumloop.
