It is a style checker built on patterns readers notice. It is not an AI detector, and it cannot tell you who or what wrote a piece. Detectors disagree with each other on the same text, which is why we do not sell ours as a way to pass them. A low score here means the prose reads like a person wrote it, nothing more.
Manual passes work on the word rows. The rhythm rows are harder: sentence length and paragraph length stay flat because they were generated in one pass, and swapping individual words does not change that. ShipCopy rewrites a draft in one go and also shows you which tells it removed, so you can keep the ones that are actually your voice.

The three that get caught most often
1. Every paragraph the same length. Real writing is lumpy.
2. A summary sentence at the end of each section that repeats the heading.
3. “Not just X, but Y” used more than once in a document.
The full 12-point list: the checklist.
30 tells with before/after examples: signals.
No. The check runs in your browser with JavaScript on this page. Nothing is sent to us, and the tool keeps working if you go offline after the page loads.
Every one of these patterns appears in writing by people. A single "However" is not a problem. A document where six different tells repeat is.
Neither predicts the other. Detectors score the same paragraph differently from each other. This tool reports what a reader would notice, which is the part you can actually act on.
