AI Text Detector per Aleksei Lystsev

AI Text Detector is a modern Firefox browser extension that helps you determine if the text on a web page was generated by artificial intelligence.
Extension Features

Full page check — click the "Check all text on page" button in the popup to analyze long text blocks. Each block will be highlighted in a red shade and get a badge with the AI probability percentage.
Selected text check — select any text on the page, right-click and choose "Check selected text for AI". The result will appear in a floating badge in the corner of the screen.
Modern design — minimalist iOS/flat-style interface, smooth effects, pleasant colors.
Security — the extension does not save your texts or use them for any other purpose.


How does it work?
The extension analyzes only visible text blocks on the page (e.g., articles, descriptions, posts). After analysis, each block is highlighted, and a badge with the probability that the text was generated by AI appears in the corner.

For selected text, the result is shown in a floating window.
