Before you scan on mobile
AI Detector Text Sample Checker
Paste the exact text you plan to check. See whether it meets the app minimum and whether the sample contains enough connected context for a more useful review.
What makes a text sample more useful?
A detector needs enough language to compare sentence patterns, vocabulary, rhythm, and structure. A heading or one short sentence contains too little context. Use the original passage without deliberately adding errors or rewriting it to chase a different score.
This readiness result is not an accuracy promise. After scanning in the AI detector app for iPhone or Android, compare the probability signal with drafts, sources, version history, and the writer's explanation.

Questions
What this tool does and does not do.
Does this tool detect AI writing?
No. It checks sample length and basic structure only. Use the mobile app to run AI and human probability analysis.
How much text should I scan?
Stealth AI Detector requires at least 200 characters. A complete paragraph or several connected paragraphs usually provides more context than a title, list, or single sentence.
Is my text uploaded?
No. Counts and readiness checks run locally in your browser. The text itself is not sent to the server or included in analytics.
Can a longer sample prevent false positives?
No sample length can guarantee accuracy. More coherent context may make a result more useful, but detection can still produce false positives and false negatives.
