Understand AI-writing signals, uncertainty, and responsible ways to use a text check.
What the check looks for
The text check reviews patterns such as repetition, sentence variation, connective phrases, detail, and direct AI disclosures. These are writing clues, not proof of authorship.
Why short text is uncertain
A short passage contains too little structure to support a stable judgment. Editing, translation, templates, and a writer's individual style can also change the signals.
Use context before action
Keep the source, date, author context, and any revision history. Do not use a detector score alone for discipline, hiring, grading, legal claims, or other high-impact decisions.
