Why Coval?
Coval is the deployment-readiness platform for voice AI agents. Simulate thousands of realistic conversations before launch, score every call in production, and sharpen your evaluations with human review — so you can ship voice (and chat) agents you trust. Whether you’re building a new agent, debugging a regression, or comparing vendors, Coval gives you a full-stack platform to simulate real conversations, track production quality, and scale with confidence. Built for:- Developers & QA — automate testing across thousands of scenarios with realistic voice inputs, IVRs, and edge cases.
- Enterprise agent ops — monitor multiple vendors, standardize metrics, and scale evaluation across use cases.
- Teams shipping fast — wire Coval into your CI/CD so you catch regressions before they reach production.
The continuous quality loop
Coval evaluates your agents at every stage of the lifecycle — from the first prompt to the millionth call.Simulate
Run thousands of realistic conversations — with background noise, accents, and edge cases — before you launch.
Observe
Score every production call in real time and surface regressions before your customers do.
Review
Route failures to human reviewers whose feedback retrains the AI judge and sharpens your metrics.
