Diagnostic: see what detectors see

Paste text below. The diagnostic runs in your browser, flags AI-typical patterns by name, and shows you exactly what triggered the score. This is a style diagnostic, not an authorship detector — the difference matters.

What you get back

The flags are the useful part. If you only look at the number, you are using the tool wrong.

Interpretation

A higher score means the text overlaps more strongly with AI-typical surface patterns. It does not prove who wrote it, and it should never be used as standalone evidence of cheating or intent. Formal prose, second-language writing, and heavily edited text can all score high without any AI involvement. For score ranges and the full interpretation boundary, see How It Works. For known false-positive risks, see Limitations.

The method hub documents everything behind this tool: how the score is assembled, what each pattern looks like with examples, where the method fails, and what changed and when. WROITER is diagnostic-first and anti-bypass — the purpose is better writing and better judgment, not evasion.
