Vapi lets businesses create AI-powered voice agents that answer calls, qualify leads, and resolve support tickets without human intervention. Users design conversational flows through a visual builder, assign voice personas, and publish agents directly to telephone numbers or VoIP platforms. The service handles inbound and outbound dialing, routing calls based on intent detection and caller data. The system routes calls to appropriate queues using intent scores, supports SIP trunking for on‑premise PBX integration, and automatically records interactions for compliance audits. Key capabilities include natural‑language understanding for multi‑turn dialogs, real‑time transcription with sentiment tags, and dynamic slot filling for personalized responses. Developers can call Vapi’s REST API to trigger agents, fetch analytics, or update scripts on the fly. The platform supports over 20 languages and regional accents, offers call recording storage, and provides a dashboard that visualizes call volume, drop‑off points, and conversion metrics. Integration hooks connect to CRMs such as Salesforce, HubSpot, and Zendesk, allowing agents to create or update records automatically. Sales teams use Vapi to pre‑qualify prospects, schedule meetings, and hand off high‑value leads to human reps. Support centers deploy agents for password resets, order status checks, and FAQ handling, reducing average handling time. Pricing is subscription‑only, with tiered plans based on monthly call minutes; a free trial is unavailable, so organizations must budget for the recurring cost. Compared with generic IVR solutions, Vapi delivers more nuanced conversational ability and built‑in analytics, though it requires some technical setup for API integration.
