From AI-powered receptionists to automated customer support, Vapi enables real-time, natural interactions that connect with people while capturing actionable insights and streamlining operations.
Teams at startups and Fortune 500 companies use Vapi to deploy voice agents, powering over 400,000 daily calls and saving hundreds of developer hours each month.
Call and experience Vapi's conversational AI in action with our phone receptionist "Macy".
Macy combines Vapi for voice handling, Twilio for call routing and OpenAI ChatGPT-4 for her conversational intelligence.
She answers all incoming calls to Revium, taking notes and passing them on to our team via Slack - capturing the caller, their number, their message, and whether the matter is urgent.
