The Problem

Your team’s already using AI. Your brand is paying for it.

Your team didn’t ask permission. They just opened ChatGPT and started writing — emails, proposals, social posts, landing pages. The output works. Sort of. Half of it is generic AI slop. The other half quietly contradicts the brand story leadership is trying to build.

The tools they’re using were built for everyone. They guess at your value props. They drift over time — welcome to “context rot.” And the more your team types into them, the further your brand drifts from the story you actually want to tell.

AI should scale your brand story.

Meet Premise

A private AI copywriter built and trained by humans, because humans are the audience

Premise is a web app your team logs into. Anyone writes the brief. Premise writes the copy.

Instead of dozens of AI chats across multiple people and platforms, all making conflicting decisions, you get this: one source of truth. Premise consolidates a single version of the brand—your vision—and makes it available to everyone.

How it Works

Premise comes in three plans. Pick one to see how it works.

1

You build each brand's Messaging Framework.

Guided onboarding captures the voice, positioning, value props, and rules for every brand you run. You can start with five and easily add more. Each becomes its own source of truth.

2

We configure your private instance.

Every brand's framework loads in alongside hundreds of pages of Prologue's proprietary copywriting expertise, so each one writes like a pro who already knows that brand.

3

Your whole team writes in Premise.

Start with up to five teammates write emails, decks, social posts, and more. Every output is on-brand, no matter who's typing or which brand they're writing for.

Why I built this

For 12 months, our consulting firm watched a painful pattern play out. We’d spend months crafting a Messaging Framework with the client. We’d “launch it” then watch their team flatten it back into mush the second they opened ChatGPT.

Seeing this powerful messaging tool get watered down by the robots was painful. Team members didn’t have the storytelling or copywriting skills to realize they were scaling not only junk, but inaccuracies or at the very least, ineffective copy. There was no great way to keep everyone on the same page, either.

We built Premise so the Messaging Framework actually scales. Not as a doc people forget about. As an AI your whole team writes through.

Your team is going to use AI either way. Premise turns that from a risk into a competitive advantage.
