About Vapi

Vapi is a developer platform for building AI-powered voice agents - automated phone systems, customer support bots, sales callers, and scheduling assistants - that sound natural enough to hold real phone conversations. The platform handles the technical stack that makes voice AI production-ready: telephony integration (Twilio, phone number provisioning), real-time speech-to-text, LLM inference, text-to-speech (ElevenLabs, Deepgram, or other voices), and low-latency response coordination that keeps conversations from feeling robotic.

For businesses that handle large volumes of inbound or outbound calls - appointment scheduling, lead qualification, customer support, surveys, reminders - Vapi enables automation that previously required either expensive call centre operations or clunky IVR systems. The developer API allows full customisation: custom system prompts, tool calling (the agent can look up appointments, update CRM records, trigger workflows), interruption handling, and call recording. Pre-built templates for common use cases (appointment booking, FAQ handling, lead qualification) reduce the setup time for standard applications. Pricing is based on per-minute usage, which makes it cost-effective for variable call volumes. Vapi is primarily a developer tool - the setup requires API integration - but the documentation is strong and the community is active. For non-technical teams, managed alternatives exist but at higher cost.
