verifiedFree trialAgentAPIMCPcoval.dev

Testing and evaluation platform for voice and chat AI agents, running simulations, production monitoring and human QA review.

What it does

Coval is a testing, evaluation and QA platform for AI voice and chat agents. It simulates thousands of realistic conversations before launch, monitors live production calls for quality drift, and routes high-stakes calls to human reviewers, feeding those judgments back into evals. It supports vendor comparisons and integrates via API, CLI and MCP.

How to use: Use Coval by simulating conversations using prompts, transcripts, workflows, or audio inputs. Evaluate agent performance with built-in or custom metrics. Track regressions, compare results, and incorporate human-in-the-loop labeling. Monitor production calls, define alerts, and analyze performance.
