If you've ever tried to get AI to write in someone's specific voice, you know it usually comes out generic or weirdly formal. This extracts the actual patterns from writing samples (emails, Slack messages, transcripts) and builds a documented voice guide with signature phrases, confidence zones, and anti-patterns. It needs at least 500 words to work properly and runs a validation test at the end to catch bad extractions. Three modes: quick snapshot for fast reference, standard full guide for AI training or ghostwriting, and deep mode with rewrites and checklists for onboarding a whole content team. The sample quality assessment is smart about filtering out platform formatting tics and overly polished copy.
