# Build Agents get started

> Pick the channel your customers reach you on and build an AI agent for it — widget, phone, WhatsApp, email, or SMS.

OpenCX agents run on the channels your customers already use. Pick the channel below and follow its introduction page — each one walks you from zero to a live AI agent on that channel.
