A useful signal for your next review
An AI detection score is an estimate, not proof of authorship. Here is how to read the feedback.
The overall score
This summarizes the detector’s assessment of the submitted passage. It does not verify the author or establish which writing tools they used.
Sentence feedback
Use sentence-level results to find passages worth a closer look. Read each sentence in context before deciding whether it needs revision.
If a paragraph is flagged, review its wording, sources, and earlier drafts. Avoid using a detector score as the sole basis for academic or employment decisions.
FAQ
Frequently asked questions
Everything you need to know about the AI Detector.
What does an AI detector do?
An AI detector examines patterns in writing and estimates how likely the text is to be flagged as AI-generated. StealthWriter provides an overall result and sentence-level feedback to help you decide which parts to review.
Can an AI detector prove who wrote a text?
No. Human writing can be flagged as AI, and AI-generated writing can go undetected. A score is an estimate, not proof of authorship. Consider drafts, sources, and the writer's process before drawing conclusions.
How much text should I scan?
We recommend at least 100 words and complete sentences with context. The detector warns that results for shorter passages may be less accurate. The public demo supports up to 500 words per scan. Daily demo limits apply.
Is an account required?
No account is needed for the detector demo. Paste up to 500 words and select Scan for AI to see your results on this page. Daily demo limits apply. Create an account for higher limits or to humanize your text.
