Does your draft read like a chatbot wrote it?

Readers have learned the phrases a language model reaches for, and they stop trusting a page when they spot them. Prose Check marks each one in your draft and says how to rewrite it. Free, no sign-up, and your text never leaves your browser.

Check a draft.

What it marks.

The same scan as slop_scan.py, the open script inside straight-prose. A test compares this page's code with that script on 3,000 files, half of them real documentation and half generated edge cases, and the two agree on every one.

Code blocks, inline code and YAML frontmatter are skipped. The scan matches English wording only.

What a script cannot see.

A clean scan proves little. The patterns that do the most damage are the ones no word list catches, and they need a reader.

Groups of threeThree adjectives, three benefits, a three-part ending. The page puts a dotted line under each list of exactly three so you can ask whether three is the real count. It cannot answer that for you.
Inflated claims in fresh wordsThe list holds the common phrases. A sentence can overstate an ordinary fact without using any of them.
A changed voiceAn edit that swaps your spelling, your rhythm or your level of formality for a smoother one reads as someone else's writing.
Sentences that say nothingPolished, balanced, and empty. If you can delete a sentence and lose no information, the scan will not tell you.

Fix it once, or stop it at the source.

This page finds the patterns after they are written. The skill it comes from keeps your agent from writing them, and edits a finished draft without flattening your voice.

Before you paste.

Where does my draft go?

Nowhere. The scan is a script that runs in this page, and your text is never sent to us, stored or logged. You can read the script at /prose/prose-core.js, and you can turn off your connection after the page loads and it still works.

Is this an AI detector?

No. It does not guess who or what wrote the text, and it gives no percentage. It marks specific wording that readers have come to associate with machine writing. People write these patterns too, and a person who writes them gets the same marks.

Will fixing the marks get my text past an AI detector?

That is not what this is for, and we have not tested it against any detector. The aim is a draft that says what it means in your own voice.

Do I have to fix every mark?

No. A mark is a reason to look. "Robust" may be the right word for a statistical method, "rather than" is often plain English, and your house style may ask for title-case headings. Rewrite where the sentence is hiding an empty claim, and leave the rest.

I got no marks. Is the draft good?

It is free of the listed wording, and no more than that. Read it once for groups of three, for claims bigger than their evidence, and for sentences you could delete without losing anything.

Does it work in other languages?

The word lists are English only. The formatting checks (em dashes, placeholders, tool markup, emoji bullets) work in any language.

What do I get for $19?

One email with your piece edited, and a short list of what changed and why. We change the sentences that carry a pattern and leave the rest in your words. If we find nothing worth changing, we refund the full amount without being asked. If you are unhappy with what you get back, reply within 14 days and we refund you.

Send us the draft that sounds wrong.

Tell us who reads it and what to leave alone. One piece of up to 1,500 words is $19 at the launch price (usually $29), back in two working days, refunded if we find nothing to change.
