The Observability and Analytics Platform for Voice AI.
Full production visibility to catch failures early, understand agent behavior, and measure real impact.





Built to Make AI Voice Agents Measurable, and Reliable
Tools you need to understand, monitor, and improve voice agents at scale - with confidence.
Understand What Your Voice Agents Are Actually Doing
Turn conversations into clear, explainable signals.
Convert every call into structured, queryable signals
Evaluate interactions across intent, outcome, behavior, and quality
See what users asked, how the agent responded, and what worked
Use default or custom evaluations for your prompts and flows


Catch Problems Before They Impact Your Users
Spot failures, drift, and regressions early.
Monitor calls for unexpected or risky patterns
Detect missed intents, hallucinations, broken flows, and cost spikes
Catch performance drift before it impacts users
Define what “bad” looks like and get alerted
Move from reactive debugging to early detection
One Clear View of Your Voice AI Operation
Visibility across your entire voice system.
Bring all voice agent data into one unified view
Track performance, failures, and trends across agents
Build dashboards from system health to deep dives
Drill down by agent, intent, or failure mode
Replace scattered logs with shared visibility


Improve With Confidence, Not Guesswork
Understand the impact of every change.
Track the impact of prompt, config, and model changes
Compare performance across versions and deployments
Spot regressions and validate improvements early
Balance quality, latency, and cost
Iterate with confidence, backed by data
Voice Agents Have Bad Days Too
Real-Time Observability
