AI Detector
AI Detector is a web tool for examining text that may contain AI-generated writing. You paste a passage into its editor and run a scan. The publisher says the report includes confidence scores and sentence-level highlights, including suspected AI sections within mixed human and AI text.
Scan a passage and inspect the highlights
The stated process has three steps: paste text, run the analysis and read the report. The service describes analyzing writing patterns and linguistic markers. It names ChatGPT, Claude and Gemini among the models whose writing it aims to identify.
The site lists essays, articles, emails and academic papers as supported input types. It presents examples for educators, publishers, businesses and recruiters. These describe the publisher's intended audiences; the captured page does not show separate scanning modes or controls for each profession. The useful output to examine is the highlighted passage and its confidence score, rather than an assumption that choosing an audience changes the analysis.
Character limits and free access
The minimum input is 50 characters. The publisher says longer passages give more reliable results. The editor allows up to 10,000 characters per scan without an account. Its FAQ says there are no paid plans and that the free API supports up to 1,000 requests per day. The homepage also advertises a free Chrome extension, although the captured evidence does not explain its controls or how to integrate the API.
Those limits make the browser form suitable for reviewing a passage at a time. For a longer document, check the relevant excerpts rather than assuming the form accepts the whole file. The described input workflow uses pasted text.
Privacy and interpretation
The publisher says it does not store text permanently, share it or use it for model training. Signed-in users retain a scan history that they can delete. Check that distinction before assuming signing in and anonymous scanning have the same retention behavior.
The homepage advertises 99.2% accuracy and scans under two seconds. The captured page provides no benchmark dataset or validation method for those figures. Treat confidence scores and highlights as the service's assessment of the text; the source does not establish those marketing figures as an independently measured basis for deciding who wrote a passage.
