Analysis result
These fields can be edited and are not proof of origin.
Why is there no AI verdict?
The experimental model performs poorly on texts independent of its initial corpus. Automatic verdicts are suspended. An AI provider named in a document is editable declared information, not proof of authorship. Detailed test results are published on the tool page.
Items to clean
No targeted character, field or label was found. This does not establish human or AI authorship.
Select the items to remove. Some invisible characters are used for hyphenation, segmentation or reading direction. Non-breaking spaces, emoji joiners and combining accents are kept.
Before/after preview
Excerpts of the affected values, not an Office layout preview. Invisible characters are shown using their Unicode code. Long passages are abbreviated.
Cleaning removes only the selected items. It does not rewrite text or remove statistical watermarks embedded in word choices.
Supported formats and limits
Word supports classic text watermarks and matching paragraphs. PowerPoint supports matching text boxes, including those on masters. Excel supports text values and simple header and footer labels.
Cleaning covers the characters and properties listed in the results, including some custom Office properties that mention an AI provider. Text files must be UTF-8.
Legacy formats, PDFs, images, encrypted or signed files and macro-enabled documents are out of scope. This tool cannot determine who wrote a text and does not rewrite it.
