Introducing the Voice Agent Builder

Hi vv,

Voice Agent Builder is now live in beta: a no-code platform for production voice agents with Grok Voice. Every account includes a free phone number. Create a voice agent in under 2 minutes, then call it from your browser.

It’s for operators and developers who want high-volume production voice agents without building the stack from scratch. You get telephony, knowledge retrieval, tools, guardrails, and observability in one place. You can also keep what you already have: bring existing phone numbers, wire your APIs, or connect MCP servers.

Most voice stacks stitch together speech-to-text, a language model, and text-to-speech, often across different providers. Every hop adds latency and new failure modes. Voice Agent Builder is one interface built for Grok Voice, tightly coupled to the model.

Sincerely,
The xAI Team
