An AI writing tool that sounds like you, with a number to prove it

Most AI writing tools ask you to describe your voice in adjectives. ScriptGrain measures it from writing you have already published: 45 attributes, from sentence rhythm to the words you reach for without noticing. Every draft then comes back with a voice-match score against that profile, so you can see how close it got instead of guessing.

Why a score matters

"Sounds like me" is not a setting you can check. A contraction rate, a comma density and a sentence-length variance are. ScriptGrain measures them in your samples, holds every draft to them, and reports the distance as a number. When a draft falls short, a polish loop revises toward your profile and re-scores, so the writing moves toward you rather than toward the model's habits.

What is set up for the US

• Priced in dollars, from $17/month, with a free plan and no card to start. Prices are shown before tax; sales tax is added at checkout only where it applies.
• American English as a first-class setting, applied at generation rather than patched over afterward. Your profile keeps the spelling your samples use.
• Built by a UK team, run for everyone: ScriptGrain is built and operated by Adapt Progress Evolve Limited. We never train AI models on your samples, and the providers we send them to are contractually barred from it.
• Sized for small teams: one voice profile on Writer at $17/month, three on Operator at $40, rather than an enterprise seat minimum. Every plan includes the API and the MCP server, so Claude and other AI tools can write in your voice too.

The free plan analyzes your writing across all 45 reference points, no card required. Generating in that voice is the paid step. US pricing: scriptgrain.com/us/pricing. Writing in British English? See the UK edition of this page.
