Use results responsibly
AI detection works best as an editing signal, not final proof. Use it to spot patterns, review flagged sections, and improve text quality with human judgment.
This tool is free, browser-based, and intended to help writers, editors, SEOs, educators, and marketers review content faster.

What is an AI Content Detector
An AI Content Detector estimates whether text appears machine-generated or human-written by looking at patterns like predictability, repetition, sentence variation, and structure. It helps editors, SEOs, teachers, and marketers make faster judgment calls on content quality and origin.
How AI Detection Works
This detector analyzes writing signals such as sentence uniformity, repeated transitions, word repetition, and variation across the text. It then generates a confidence estimate, a sentence-level view, and supporting signals like perplexity and burstiness to make the result easier to interpret.
Accuracy & Limitations
No AI detector is perfect. Highly edited AI text can look human, and polished human writing can occasionally look machine-like. Use detection scores as directional guidance, combine them with editorial review, and avoid treating any single score as final proof.

FAQs
They can be useful, but they are not perfect. Detection is best treated as probabilistic guidance, not certainty.
Sometimes. Heavily edited or personalized output may look more human, while predictable raw output may be easier to flag.
Google focuses more on quality and usefulness than whether content was AI-assisted. Thin, repetitive, low-value content is the bigger risk.
Make the writing more specific, vary sentence structure, strengthen original thinking, and revise sections that feel generic or predictable.
Very uniform structure, repeated phrases, low variation, and generic transitions can make even human text appear machine-like.
No. This version runs client-side in the browser and does not store or share the text.
Yes. The tool is optimized for larger inputs, though very large documents may take slightly longer in deep mode.
Review flagged sentences, improve specificity, vary structure, and use related cleanup or rewriting tools when needed.
