)Everything you need to understand your AI
Built for product & engineering teams who refuse to fly blind with their LLM applications.
Capture Everything
Log every LLM interaction — inputs, outputs, latency, tokens, and user context. Two lines of code to get started.
Analyze at Scale
Automatic quality scoring, topic clustering, and anomaly detection. Understand patterns across thousands of conversations.
Surface Insights
Get actionable dashboards showing user satisfaction, failure modes, and optimization opportunities. Stop guessing, start knowing.
Ship with Confidence
Catch regressions before your users do. Set alerts on quality drops, hallucination rates, and latency spikes.
