Voice-native conversational AI agents for customer and employee touchpoints
A voice-native platform for building and orchestrating AI agents, with agent and model selection, rule-based actions, and human-assisted resolution.
Agents are designed to keep listening and understanding through interruptions, background noise, and the unpredictable flow of real conversations.
Layered guardrails at instruction, task, function, and channel level, a proprietary PII-detection LLM, tenant isolation, encryption, and full audit logging.
Deploy agents to digital channels and physical locations — phones, drive-thrus, in-car systems, kiosks, and employee tools — from a single system.
