AI detectors look for statistical patterns: predictable word choices, a steady sentence rhythm and familiar structure. Some human writing has those patterns too. On our benchmark, 0.6% of human-written documents are wrongly flagged as AI. That's low, but across thousands of essays it isn't zero.

## Writing that's more likely to be flagged

- **Formulaic genres:** lab reports, abstracts, legal text, cover letters and product descriptions follow fixed templates.
- **Very short pieces:** with only a few sentences, there's little signal to go on.
- **Text polished by tools:** heavy use of grammar checkers or rewording apps smooths out the quirks that make writing look human.
- **Writing in a second language:** careful, textbook-correct prose can read as more uniform.
- **Well-known passages:** famous speeches, definitions and boilerplate are everywhere in the data models learn from, so they read as model-like.

## If your own writing was flagged

1. Look at which sentences are highlighted. If it's a handful of generic lines, the result is weak evidence.
2. Gather your drafts. Version history in Google Docs or Word, notes and outlines show how the work developed.
3. Ask for a conversation. Explaining your argument and sources in your own words is the most convincing evidence there is.

## If you're reviewing someone else's work

Treat a low human score as a reason to ask questions, not as proof. Compare the work with the writer's earlier pieces, look at drafts, and talk with them. [Talking with a writer about a flagged result](https://winstonai.ai/help/discussing-a-flagged-result) has a simple structure for that conversation.
