Simulation & evals for voice and chat agents
Built by experts in autonomous testing
Tired of manually testing your AI agents?
Simulate thousands of scenarios from a few test cases. You create the prompts, we simulate environments to test your agents from all directions.
AI-Powered Simulations
We chat with your agent to generate test cases.
Voice AI Compatible
We can call your agent via voice just as easily as text.
How Coval works
Simulate conversations
Simulate agent conversations using scenario prompts, transcripts, workflows, or audio inputs, with customizable voices and environments for advanced testing.

Listen to what our customers say
“Coval’s simulation and evaluation platform has been the game changer for us. Before Coval, we were spending countless hours pulling our hair out trying to make sure our voice agents behaved the way our customers wanted. Now, with a few tests we can deploy production ready voice AI agents in a fraction of the time.”
