Simulate real users.
Ship reliable agents.
Watch a synthetic driver call your voice agent in Spanish, switch to English mid-call, and trip an edge case before it ever reaches a customer.

synthetic users
Drivers act like real users. Not like scripts.
A Driver is a synthetic user with personality, context, and a goal. They interact with your agent across long, multi-turn conversations and expose edges your QA scripts won't — at a scale your team can't match by hand.
Voice
Voice agents, tested like real calls.
Synthetic callers in 120+ languages, with the noise and clipping and crosstalk your real customers actually call from. Audio, transcript, and trace land on the same timeline — so Conversation Designers and Engineers debug the same call, in the same view.
Exploration
Drivers explore.
Traditional QA writes scripts and asserts on outcomes you already know to check. Drivers don't have a script — they have personality and a goal, and they wander. What you get back is a map of every behavior your agent actually has, including the ones nobody could have written down beforehand.
"In the first run we found 47 edges across our 12 happiest paths. Six of them were already shipping in production."

Eval in CI
Gate every PR on real conversations.
Run synthetic-user simulations on every commit. No more vibe testing. Catch regressions in tone, policy, tool use, or routing before they ship — with judge, symbolic, and audio-based evals on the same scorecard.
Closed Loop
Production failures become tests.
Every escaped failure in production becomes a synthetic scenario that runs on your next PR. Your test library gets stronger every week — without anyone hand-writing new tests. The agents that survive Okareo don't just ship; they get harder to break.
