Kept in this browser only and never uploaded. It records the verdict, not the file: no image, no share link and nothing that identifies you.
What this result can tell you.
The detector looks for patterns associated with synthetic or generated content. It cannot prove who made a file, which tool was used or whether the content is truthful.

Unknown is a valid outcome
Signals, not proof.
Uploads are temporary and are not used for model training by default. Avoid sensitive, unlawful or children’s media.
Review writing-style signals without guessing authorship.
Text detection is especially sensitive to genre, length, language and editing. Use it as triage for further review, never as standalone evidence.
What the text checker does
The checker evaluates a coherent passage for patterns associated with generated writing and returns a warning-only result. It does not search a universal database of AI text, identify a specific model or determine who wrote the passage.
The minimum input protects against meaningless results from headings, short replies and lists. Longer input is not automatically conclusive: a document can mix original writing, quotations, templates and edited generated material.
Prepare a useful sample
Paste at least 60 words from one coherent section
Keep the original language and punctuation
Remove navigation, signatures and repeated boilerplate
Analyse distinct authors or sections separately
Do not combine unrelated passages merely to reach the minimum. That creates an average without a clear interpretation.
Why text detector results require caution
Human writing can be concise, predictable or highly polished. Legal clauses, product descriptions, school assignments, translated text and corporate templates may share stylistic regularities. Grammar correction and extensive editing can also change the measurable style. Generated text can meanwhile be rewritten until familiar patterns weaken.
A warning therefore cannot establish misconduct, plagiarism or authorship. If the context matters, review citations, factual consistency, document history, drafts and the writer's ability to explain their process. Give the person a meaningful way to respond.
Responsible uses
Editorial and content review
Use the signal to select passages for source checking, disclosure review and fact verification. Keep the final editorial decision with a reviewer.
Education and hiring
Do not automate sanctions or rejection. Compare drafts and references, assess the work itself and document why additional review was necessary.
