Why we built a tier dial (and why a prompt isn't enough)

Most AI writing tools give you a prompt box. You type what you want, hit enter, and hope. Supabrief has a dial. P0 major · P1 minor · P2 patch.

A dial beats a prompt for a simple reason: you can't write a good prompt for a bug-fix changelog and a P0 launch brief and a P2 patch note without rewriting the prompt every time. So you don't. You use a prompt that's mediocre for all three.

The tier dial does three things a prompt can't:

1. It controls word count. P0 briefs run 400–600 words per document. P2 patches run 100–200. If you prompt "write a launch brief" you get 400 words whether the feature is a flagship or a typo fix. 2. It controls section count. P0 gets positioning, audience, content angles, SEO, suggested headlines. P2 gets *what shipped* and *what users do next*. You don't need positioning for a typo fix. 3. It tells the model the reader is busy. A P2 changelog tells your customer what broke, what's fixed, and what to do next — in one screenful. A P0 brief tells your PMM the full story.

The persona dial is the same idea for a different axis. The battle card for Sales leads with the elevator pitch and objections. The brief for Marketing leads with positioning. The changelog for Customer leads with what shipped. Same source — three leads.

The point: prompts are a drag. Dials are a product.
