Quotient AI
Real-time monitoring and evaluation platform for catching AI failures in search, RAG, and agents.
Quotient AI is an observability and evaluation platform built for teams shipping AI-powered features. It continuously monitors production AI systems—including search, retrieval-augmented generation (RAG), and autonomous agents—to surface hallucinations, retrieval errors, and other quality issues before end users encounter them. The platform combines automated evaluations with real-time alerts, helping engineering and ML teams diagnose root causes, track regressions across model or prompt changes, and maintain reliability at scale. By instrumenting AI pipelines, Quotient gives developers visibility into how their applications actually behave in the wild rather than relying solely on offline benchmarks.
