What it means here In this channel's material, a style guide is the codified set of writing rules and conventions that an editorial team encodes into an AI system so drafts are checked against it automatically. Every's editor in chief Kate Lee describes a 400-rule style guide loaded into a Claude project, which drafts pass through before they ever reach a human editor — a way of using AI to raise the floor on quality while the taste layer of editing stays with people.
