What are Vapi and VoxImplant?
Vapi is a platform that helps developers build voice AI agents that can talk with people over the phone or inside apps. Instead of coding audio streaming, transcription, and text to speech from scratch, developers connect these pieces through Vapi and focus on the conversation logic.
It combines speech to text, a language model, and text to speech, and lets teams pick their preferred providers or bring their own keys. Agents can answer or place calls, use tools to look up data or take actions, and hand off between specialized assistants for more complex tasks.
Companies like Amazon Ring and Intuit use Vapi to power support, sales, and scheduling calls at scale.
