    Vapi AI

    Productivity

    Vapi is a developer-first platform for building, deploying, and scaling real-time voice AI agents. It provides APIs and infrastructure for creating natural voice assistants that can make and receive phone calls, integrate with large language models (LLMs), connect to business systems, and automate customer interactions. Rather than supplying its own AI model, Vapi orchestrates speech-to-text (STT), LLMs, text-to-speech (TTS), and telephony providers into a unified voice agent platform.

    Cons

    • Primarily designed for developers
