Your brand guide,
enforced the moment
an agent writes it.

WHAT IT CATCHES

Five checks, one verdict.

Colors & fonts

Catches off-brand colors and fonts, even inside generated PowerPoint and Word themes.

Banned & required terms

Our pricing is finally cheap for everyone.

✕ FAILuse "affordable"

Catches banned words and phrases anywhere in the text, and explains why each one isn't allowed.

Outdated brand elements

Catches old logos even when they've been resized, recompressed, or renamed, not just exact copies.

Tone & voice

"Dear Valued Customer, we are writing to inform you"

ADVISORYtoo formal for an email

AI compares the tone against examples of your own good and bad writing, with different rules for different document types and audiences.

WHAT YOU SEE

A verdict, not a lecture.

$ stylist check -ruleset rules/brand.yaml page.html

FAIL  page.html  (ruleset: acme-brand-v1)
  page.html:5   [colors] color #ff4136 is not in the allowed brand palette
  page.html:10  [terms] banned term "cheap" found: use "affordable"

CI-friendly exit codes: 0 = pass, 1 = violations found, 2 = error.

WHERE IT RUNS

Catch it before it ships, not after.

git pre-commit

checks your changes before the commit lands

Agent hooks

Claude Code, Codex: the agent fixes its own output right after writing

CI / CLI

stylist check dir/, the last check before anything ships

core checker

embedded, or a central API server

dashboard

every check, tracked over time
