Brand voice consistency.
Catch drift before it ships.

Paste a baseline piece (something on-voice) + a candidate piece (the ghostwriter / AI-assisted draft you're checking). We compare seven stylistic axes — formality, sentence length, sentence rhythm, vocabulary richness, first-person pronouns, hedging, jargon density — and return a 0-100 consistency score with per-axis drift detail. Pure client-side, no LLM, nothing leaves your browser.
