Who it's for

Product, support, and agency teams who need to build and ship custom AI chat and voice agents on their own business data, with enough control for engineering and enough visual tooling for non-developers.

What you get

A drag-and-drop Workflow Builder for conversation logic, a Knowledge Base that trains agents on your own data sources (docs, sitemaps, help centers), model-agnostic LLM support, native CRM/support tool integrations, an embeddable chat widget, and analytics with full conversation transcripts.

How it works

You design agent logic visually in Workflows/Playbooks, connect a knowledge base and third-party tools via Functions and native integrations, then deploy the agent through an embeddable web chat widget, phone/telephony, or a custom interface via the Conversations API.
