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.
