Your voice, measured and multiplied, so the newsletter still sounds like you at 11pm on a Sunday.

The solo bind

You know the drill. Consistency beats volume, everyone says so, but the algorithm wants volume anyway. So you post when you can, write when you're not doing the actual work, and something's got to give.

Usually it's your voice. Fair enough, it's the easiest thing to sacrifice at 11pm.

Except that's the one thing nobody else can copy.

Your voice is the asset

Anyone can copy your pricing. Your positioning, your offer, your funnel. They cannot copy the specific way you explain things, the phrases you reach for, the rhythm of how you build an argument.

That's not branding. That's stylometry, and it's measurable.

ScriptGrain runs a two-pass analysis across 45 attributes of your actual writing: sentence length, contraction rate, how you open paragraphs, whether you hedge or state things plainly. Then it holds that as a constraint, not a suggestion, every time you generate something new.

The loop, in practice

  1. Profile once. Paste in posts, emails, whatever you've already written. Two-pass analysis, done in minutes.
  2. Generate in your voice. Posts, newsletters, emails, drafted to match, not to sound like a generic LinkedIn post from 2023.
  3. Check the score. Every draft comes back with a voice-match score, so you're not guessing whether it sounds like you.
  4. Edit lightly, publish. Small tweaks, not a rewrite. That's the whole point.

Newsletter writers get the same process, just pointed at back issues. We measure the voice that earned your subscribers from issues you've already sent, then draft each new one inside it. Every draft carries a voice-match score, and the newsletter-specific workflow goes further: it learns from your edits, so each issue needs a lighter touch than the last.

One voice profile. One full analysis. All 45 attributes, laid bare, before you pay a penny.

When you're ready to publish at volume

Writer, £12/month

One voice profile. Built for the solopreneur running one brand, one voice, everywhere it needs to show up.

Operator, £29/month

Three profiles. For the founder juggling separate brands, or a business voice and a personal one that shouldn't blur.

(Studio and Agency tiers exist too, for bigger teams with more voices to manage. Details on the pricing page.)

The bit that matters

You didn't start a one-person business to sound like everyone else's newsletter. Volume was never really the problem. Sounding like you, at scale, was.

That's what this fixes.

No card. No catch. Just the 45 things that make your writing yours.

A week of content with one profile

Here's what a realistic week looks like when you're the writer, the editor and the person who also has to do the actual job. Nothing heroic. One profile, built once, doing the repetitive part.

Say Monday is your newsletter. You jot the idea in a line or two, generate a draft against your profile, and check the voice-match score that comes back. On-voice drafts typically land between 0.85 and 0.95. If yours lands at 0.88, you edit a sentence or two and send it. If it lands at 0.6, you know before your readers do.

Wednesday is a handful of posts. Same profile, different format. Thursday might be a landing page tweak or a reply to a customer email that needs to sound like a person, not a template. Friday, you look at what you changed and what you didn't.

That last bit matters. The app learns from the edits you save, so the fixes you keep making stop being fixes. So the week gets lighter. You're rewriting less, and that's where the time goes.

And to be fair, the profile isn't locked inside one tool. It reaches ChatGPT, Claude, Gemini, Cursor, Meta Muse and any MCP client through the MCP server and the REST API, read live each time. You keep using what you already use. It just arrives knowing how you write.

What to measure first

Start small. You don't need all 45 attributes in your head to get value from them.

The first thing to give the profile is your best recent writing. Not your most polished; your most you. The newsletter that got the reply "this sounds exactly like you". Two or three more pieces alongside it, ideally across formats. The recommendation is three or more pieces and about 3,000 words, though a single sample of 50+ words is enough to get a profile started. Extraction usually takes under a minute (the median measured was 39 seconds).

Then look at a handful of attributes before anything else:

  1. Average sentence length and its variance. This is rhythm. Two writers can average the same length and sound nothing alike.
  2. Contraction rate. It tells you how warm or formal you really are, as opposed to how you think you write.
  3. Confidence versus hedging. Do you state things plainly, or qualify everything?
  4. Opening style. How your paragraphs and pieces begin.

Why these? Because they're the ones a reader feels without naming. Get them right and a draft sounds like you from the first line. Get them wrong and it's the LinkedIn voice from 2023, no matter how good the ideas are.

You'll probably be surprised by at least one number. That's useful. It's a measurement, not a flattering mirror.

When someone else writes for you

At some point you'll hand work to a freelancer or an assistant. This is where voice usually leaks away, quietly, one sensible edit at a time.

The old fix was a style guide. Three pages of adjectives: "friendly but professional", "punchy". Fair enough, but those words mean something different to everyone who reads them.

The profile gives them something measurable instead. Your freelancer writes a draft, it gets scored from 0 to 1 against your profile, and the result comes back with per-feature deltas: the draft's value against yours. So the feedback isn't "make it sound more like me". It's "your sentences average longer than mine, and you've used far fewer contractions".

A rough guide to reading the score:

If a draft comes in short of where you want it, Polish revises it toward a target score. The default is 0.9. You can do that yourself, or ask the writer to do it before it reaches you.

So you stay the owner of the voice without being the bottleneck for every sentence. Somebody else holds the pen. You hold the standard.
