Check if text was written by AI — free and private
AI Text Detector is a free, browser-based tool that checks whether a piece of text was written by AI. You paste an essay, article, post, or story, press Analyze, and get an overall AI percentage with a confidence level, plus per-sentence highlighting of passages that read as AI-generated.
Every analysis returns an overall AI percentage labeled as AI-generated, Mixed, or Human, together with a confidence level.
Each sentence is scored individually and AI-like passages are highlighted in the text so you can see exactly which parts read as AI-generated.
The analysis runs entirely in your browser — text is never uploaded, stored, or saved anywhere.
Paste any text (minimum 50 words) into the editor, press Analyze, and get results immediately; a Clear button resets the input.
Enter any essay, article, post, or story into the text box (at least 50 words; longer texts give more reliable results).
Press Analyze and every sentence is scored for AI-likeness, producing highlighted AI-like passages, an overall AI percentage, and a confidence level.
See the score categorized as AI-generated, Mixed, or Human, and inspect which specific parts of your text read as AI-written.
