Okareo. Simulate real users.

Okareo is a platform designed to simulate real users for testing and evaluating voice and text agents. Its core function is to help teams ship reliable conversational AI by exposing edge cases and behaviors that scripted quality assurance methods might miss. The platform uses synthetic users, referred to as Drivers, who possess distinct personalities, contexts, and goals, enabling them to interact with agents across long, multi-turn conversations. These Drivers act more like real customers than scripted bots, allowing for the discovery of unexpected issues and edge cases at a scale beyond manual testing.

A notable feature of Okareo is its support for both voice and text modalities within a single platform, eliminating the need to switch tools when testing different agent types. Synthetic callers can operate in over 30 languages and dialects, and are capable of introducing real-world audio conditions such as noise, crosstalk, and clipping. The platform provides synchronized audio, transcript, and trace data on a unified timeline, enabling conversation designers and engineers to debug calls collaboratively. Users can observe scenarios such as a bilingual caller switching languages mid-conversation, with the system capturing and evaluating the agent's response in real time.

Okareo integrates into continuous integration (CI) workflows, allowing teams to run synthetic user simulations on every code commit. This enables gating of pull requests based on real conversational quality, with various evaluation methods—including judge, symbolic, and audio-based assessments—consolidated on a single scorecard. When failures occur in production, Okareo can turn these incidents into new synthetic test scenarios, strengthening the test library automatically and helping prevent regressions.

The platform is built for cross-functional teams, including conversation designers, engineers, machine learning specialists, and QA professionals, providing a shared workspace for monitoring and improving conversational agents. " Its features are aimed at both enterprises and startups shipping production-ready voice and text agents.
