Most businesses' brand voice lives in an old style guide, a few decks and the heads of the people who've been there longest. This plugin goes looking through your connected tools (documents, Slack, call transcripts) for how your business actually writes and talks.
/brand-voice:discover-brand finds the material, /brand-voice:generate-guidelines turns it into clear rules, including a "we are / we are not" list and preferred words, and /brand-voice:enforce-voice writes new copy to those rules. The voice stays the same while the tone shifts between a cold email, a proposal and a LinkedIn post. Where your documents disagree, it lists open questions with a suggested answer for you to confirm.
Tribe AI built it as a launch partner, and it sits in Anthropic's official Knowledge Work directory. For now it works for one person at a time; team-wide rules are on the way.
