Own your AI, don't rent it - Conversational AI platform for building custom voice and chat agents with self-hosted models.

The most configurable API to build leading voice AI products and scale phone operations.
Vapi is a developer platform for building voice AI agents, providing the infrastructure to create voice experiences. It allows for natural conversations, making and receiving phone calls, integrating with existing systems and APIs, and handling workflows like appointment scheduling and customer support. Vapi combines speech-to-text conversion, intelligent response processing, and text-to-speech conversion, with control over components like OpenAI, Anthropic, Google, Gladia, Deepgram, and ElevenLabs. It offers two main primitives: Assistants for fast iteration and common use cases, and Squads for multi-assistant setups. Key capabilities include real-time conversations, phone and web integration, tool integration, and multi-assistant orchestration, deployable via CLI and SDKs.
