Free AI Text Detector
Check text with a real AI language model that measures how predictable every word is, plus writing-pattern analysis: sentence rhythm, repetition, readability, vocabulary diversity, and more.
Free, private, no upload to a server. Everything happens in your browser.
All analysis happens 100% in your browser: plain, auditable writing-pattern statistics, plus an optional small AI language model (about 100 MB, downloaded once from this site) that runs on your own device. No external API, no server. Your text never leaves your device.
AI detectors can make mistakes. Results here are estimates based on writing patterns and should not be used as definitive evidence of cheating, misconduct, plagiarism, employment violations, or authorship. Edited AI text can appear human, and genuine human writing — especially from non-native English speakers or anyone with a plain, consistent style — can score as AI-pattern-like. Treat every number on this page as a prompt to look closer, never as a verdict.
