Introduction
Vapi is the Voice AI platform for developers.
Vapi lets developers build, test, & deploy voice AI agents in minutes rather than months — solving for the foundational challenges voice AI applications face:
Simulating the Flow of Natural Human Conversation
Turn-taking, interruption handling, backchanneling, and more.
Realtime/Low Latency Demands
Responsive conversation demands low latency. Internationally. (<500-800ms voice-to-voice).
Taking Actions (Function Calling)
Taking actions during conversation, getting data to your services for custom actions.
Extracting Conversation Data
Review conversation audio, transcripts, & metadata.
Implemented from scratch, this functionality can take months to build, and large, continuous, resources to maintain & improve.
Vapi abstracts away these complexities, allowing developers to focus on the core of their voice AI application’s business logic. Shipping in days, not months.
