# Steer your AI SDR in plain English

Write a short brief for each campaign the way you'd brief a new rep, and your AI follows it on every email, every follow-up. Set the tone, the offer, who to target, and the rules it must never break, no prompt engineering, no rigid templates. Change a line and the whole campaign adapts on the next send.

* Brief it in plain English, no prompt tricks or template syntax
* Set tone, offer, targeting, and guardrails per campaign
* The AI applies your instructions to every email and follow-up
* Update anytime and the campaign adapts on the next send
