AI Scanner

AI Scanner is a web-based tool that analyzes text to identify content generated by AI models. You paste up to 3,000 words of text or upload a document, and it provides a score indicating the likelihood that the content is AI-generated. It also offers a detailed, sentence-by-sentence breakdown, highlighting specific phrases that appear to be machine-written, even if they were later paraphrased or edited by a human. The process is quick, taking just seconds to complete.

The tool is designed to detect content from a wide range of popular language models, including ChatGPT, Claude, Gemini, and Perplexity. It claims 99% accuracy in its benchmark tests and is continuously updated to keep pace with evolving AI models and paraphrasing techniques. A significant feature is its focus on security; it processes text with encryption and does not store your data after the analysis is complete. It handles both raw AI output and content that has been manually tweaked to avoid detection.

This tool is most useful for students at all levels—high school, college, and graduate—who want to check their assignments for unintentional AI patterns before submission to avoid academic integrity issues. It's also valuable for educators verifying student work and researchers ensuring their papers don't get flagged by journals. Non-native English speakers, whose writing can sometimes be mistakenly flagged by other detectors, can use it to identify and rewrite problematic sentences.
