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.
Build, test, and deploy production-grade voice AI agents over API
Configure speech recognition, an LLM reasoning layer and text-to-speech through one API instead of integrating several vendors separately.
The platform handles real-time audio streaming, interruption handling and call state so conversations feel natural and responsive.
Provision Vapi phone numbers or bring Twilio, Vonage or Telnyx, and support both inbound and outbound calling from the same agent.
Simulate calls before launch, then track transcripts, effectiveness metrics and compliance signals across every production call.
