01
Pick your AI human
AI Rep, Interviewer, Healthcare Agent, or Coach. Each ships pre-built with industry personas, knowledge templates, compliance guardrails, and conversation flows for your vertical.
02
We co-design the experience
Our team shapes the persona with yours, the voice, the face, the expertise, and how it handles the hard moments, then wires memory, escalation, and your CRM, ATS, EHR, or LMS.

Launch, learn, and tune
Go live in 2–4 weeks via API, iframe, or a direct link. We monitor performance, tune the persona, and sharpen your AI human over time. You get the AI, we keep it sharp.
