Simulate, evaluate, and benchmark your voice AI - the way humans experience it
Real-world scenario simulation, automated evals, and human-grounded studies. Bring any voice AI model. Get results in hours.
One platform
Both simulation modes. One platform
Kairos runs fully automated agent-to-agent simulations for scale and human-to-agent conversations for ground truth, grounded in the real-world scenarios your model will actually encounter. Structured results collected automatically after every run.
What Kairos evaluates
Built for the questions voice teams actually need answered
Does the agent complete the task correctly while maintaining appropriate tone across a complex multi-turn scenario?
Does the agent recognize and adapt when a caller shifts from calm to frustrated mid-conversation?
Does the model perform consistently across 50 runs of the same scenario, or does it break at the edges?
Did the latest checkpoint regress on empathy quality compared to last week's build?

Real-world simulation
Simulate the scenarios your model will actually face
Kairos generates realistic conversation scenarios from your use cases, covering hostile callers, distressed users, complex policy edge cases, and multi-turn interactions. Run agent-to-agent for scale or human-to-agent for ground truth. Both on the same platform.
Benchmarking & regressions
Run against public and private benchmarks. Catch regressions before they ship
Kairos runs your model against industry-standard public suites or your own private benchmarks, and tracks performance across every release. When a dimension regresses, you find out before it reaches production.

Human studies
Rated against what only humans can judge
Human raters evaluate your voice AI across dimensions like naturalness, empathy, expressiveness, and task success - giving you both objective scores and subjective qualitative signal. Compare any number of models head-to-head, on the same scenarios, with the same raters.
