Vapi AI is a browser and API platform for building and deploying advanced voice-enabled agents. It combines speech recognition, a language model and natural-sounding text-to-speech inside one modular system, allowing developers to automate support lines, qualification calls and in-app voice interactions without building their own voice infrastructure.
Agents are configured through the dashboard or CLI. They listen in real time, process intent with the language model you choose, respond through the selected voice engine and can execute backend actions such as database lookups or API requests. Vapi delivers low latency of roughly eight hundred milliseconds and supports more than one hundred languages for global use cases.
The platform is designed for developers. You can bring your preferred STT provider such as Deepgram or Whisper, select voice engines like ElevenLabs or PlayHT, integrate telephony through Twilio or Telnyx and build complex workflows involving routing logic, multi-agent systems and CRM or ERP integrations.
For businesses, Vapi supports high-concurrency workloads along with HIPAA and SOC 2 Type II compliance and private deployment options. It is built to operate as reliable enterprise-grade infrastructure.
Vapi AI provides the foundation to move from a simple idea to a fully operational voice agent without assembling an entire voice stack from scratch. It is suitable for teams that need automated calls, voice-based assistants or conversational systems that extend far beyond basic chatbots.
