AI CODE DETECTOR GUIDE
Does selecting an unsupported file clear pasted code?
No. If a chosen file or folder contains no supported extensions, the file selection is cleared but the editor text stays. Clicking Scan then analyzes that existing text as “Pasted code.”
The editor text is analyzed in your browser; submitted code is not uploaded.
Why code may still be scanned
The file picker filters chosen entries by extension. When none are supported, the page clears the selected-file list and displays a message, but it does not erase text already in the editor. The scan action uses editor text whenever no supported file remains selected.
This can happen if you pasted code before choosing an unsupported file. It can also happen after a folder scan, because the editor contains the first selected file's text. That remaining text is treated as a single pasted-code input, not as a scan of the rejected file or folder.
Check the input before scanning
Look at the editor and its file label before clicking Scan. Remove or replace any old text if it is not the code you intend to review. If the editor is empty and no supported files are selected, the tool does not produce a report.
Any resulting score describes configured heuristic matches in the text that was actually scanned. It is not proof of authorship.
For the file-selection message itself, see what happens when no supported files are selected.
