Respan

Respan (Keywords AI, Inc.) is an LLM engineering and AI observability platform that traces, evaluates, optimizes, deploys, and monitors AI agents—capturing every prompt, tool call, and response, reproducing end-to-end execution paths, and providing custom dashboards with real-time alerts. It serves founders, engineers, product teams and healthcare organizations (HIPAA BAA available) and differentiates by combining human review, code checks, and LLM judges in a single evaluation workflow, offering prompt/tool/model/workflow versioning and UI-driven promotion to production alongside a single gateway that routes across 500+ models.
