About ScriptGrain

ScriptGrain analyzes writing you provide and builds a measured voice profile, so AI-assisted posts and articles read as if you wrote them. It examines 45 reference points across eight groups, from lexical habits and syntax to tone, rhetoric, punctuation, function words, content patterns and cadence.

A browser preview measures six signals, namely rhythm, syntax, punctuation, lexicon, rhetoric and cadence, from 120 words or more without uploading anything, and the full profile takes about 45 seconds and is free with no card. Drafts are scored for voice match out of 100, shown on the page as moving from a model's plain draft to a profile-guided draft and then a polished one. It works inside the AI tools you already use, with ChatGPT and Claude connections, and you can also write in ScriptGrain itself.

The site says it never trains models on your samples, offers sample voices including a shared Wry Builder profile, and publishes a controlled test comparing four voice profiles, with its method and limitations.
