AI CODE DETECTOR GUIDE
What happens if no supported files are selected?
The tool does not start a file scan. If a selected file or folder has no recognized source-file extensions, the selection is cleared and the page shows that no supported source files were selected.
File selection and analysis happen in your browser; submitted code is not uploaded.
Why a selection can be empty
The folder picker keeps files whose extensions the tool recognizes. If none of the chosen files pass that check, there is no source text to analyze, so no score or matched-rule report is produced. The file name alone does not make an unsupported file type eligible.
For a supported file, the tool reads its text locally before analysis. You can select a supported source file or paste code into the editor to provide analyzable text.
What this message does and does not mean
An empty selection is an input-state message. It is not a zero score and does not say anything about whether code looks human-written or AI-generated.
When code is analyzed, the score summarizes configured heuristic patterns and the report can show matched rules and flagged lines. Those signals are not proof of authorship.
