Keywords AI

Keywords AI, now branded Respan, is for developers and AI product teams building LLM-powered apps and agents who need one place to route model requests and understand how their systems behave in production. Its AI gateway connects applications to models from multiple providers through one API, with options for fallbacks, request caching, and spend and rate limits. The platform also records traces across model calls, tool use, retrieval, and agent steps, capturing inputs, outputs, latency, and cost to help teams debug workflows. Dashboards track requests, errors, token usage, and spending, with configurable alerts. Teams can evaluate outputs against datasets, compare model or prompt changes, and score sampled production traffic using code checks, AI judges, or human review. It is suited to teams that want model routing, LLM observability, and evaluation tools in a single platform.
