Grain · Editor for AI-drafted text

Make the draft sound like you wrote it.

Grain marks the phrasing that gives an AI draft away, tells you why it stands out, and offers a sentence that sounds like you instead.

This is the editor. The coloured underlines are the tells. Select one to see why it was flagged, choose how far the rewrite should go, and put the new sentence into the draft.

The draft is still yours; the editor just shows you where it stopped sounding like you.

  • Repeated opener
  • Stock phrase
  • Filler transition
  • Replaced by you
Select a marked sentence

Marked sentences are the ones with a coloured underline. Select one to see why it was flagged and what a rewrite could look like at three strengths.

01

See your draft the way a reader does

The fourth paragraph in a row opening the same way. The transition that connects nothing. The phrase everyone has read a thousand times. Grain marks them in place and says why each one stands out, so you start to catch them yourself.

  • Repeated openers, stock phrases and filler, marked in the text
  • A plain reason on every mark
  • Nothing is rewritten while you read

In today's fast-paced world, teams write more than ever. It is important to note that most drafts start with a model. Furthermore, they share a shape. Readers notice within a paragraph.

  • Set phrase that adds nothing
  • Second sentence opening this way
  • Transition that connects nothing
02

Choose how far to go

Some sentences need one word swapped. Some need the rhythm broken. Some need to be said a different way altogether. Set the strength where you want it and Grain answers at that level, instead of rewriting the page out from under you.

  • Light, medium or deep, set per passage
  • One sentence at a time, in your order
  • Take it, edit it, or keep your original

Furthermore, these drafts tend to share the same shape.

The drafts share a shape: the same openers, the same rhythm.

Set it per passage. The rest of the page is left alone.

03

Your meaning survives the edit

A better sounding sentence is worthless if it quietly drops a number or invents a claim. Every alternative is checked against your original first: numbers, names, dates and quotes stay exactly as you wrote them, and anything new is marked as new.

  • Numbers, names and quotes preserved
  • Additions shown as additions
  • Nothing accepted silently
Checked against your original

We cut deploy time to 14 minutes for Northwind in March.

Deploys at Northwind took 14 minutes by March.

  • Numbers, names and dates unchanged
  • Nothing added that you did not write
04

It sounds like you, not like a style guide

Paste a few paragraphs you wrote yourself and Grain uses them as the reference for word choice and sentence length. Your samples stay in your workspace and are never used to train anything.

  • Your own writing as the reference
  • Samples stay yours and can be deleted
  • Every change kept in a history you can revert
Your voice
  • Release notes, March
  • Onboarding email
  • Blog post about queues

Short sentences. Contractions. Almost no adverbs. Grain matches that when it suggests a line, and your samples stay in your workspace.

Who it is for

Built for the people who do this every week.

  • Technical writers

    Docs that start as a model draft and have to read like your product, in your voice, at the pace you actually ship.

  • Marketing teams

    Pages and posts that sound like a person wrote them, because a person chose every sentence that changed.

  • Founders and small teams

    You write your own copy between everything else. Grain is the editor you would hire for the second pass.

Questions

Good things to ask.

When can I use it?

Grain is being built now. The editor on this page is a working sample of the flow with a fixed draft. Join the early access list and we will email you once, when you can bring your own.

Will it get my text past an AI detector?

We do not build for detectors, measure against them, or make claims about them. They are unreliable, and a product aimed at them would be a worse editor. Grain is for making a draft read like you.

Is this a grammar checker?

No. Grammar tools look for mistakes. Grain looks for sentences that are perfectly correct and still sound machine made: the repeated opener, the empty transition, the hedge on a hedge.

Does it rewrite my whole document?

Only if you accept every suggestion, one by one. Grain never edits in the background. You select a sentence, you look at the alternative, you decide.

What happens to my writing?

Your drafts and voice samples stay in your workspace, are used only to produce alternatives for you, and are never used to train models. You can delete any of it at any time.
