AIGC Check is a free online tool that helps you determine whether a piece of text was written by a human or generated by AI. We provide fast, privacy-friendly, and probability-based analysis using advanced linguistic pattern recognition.
As AI-generated content becomes increasingly common across the web, it is more important than ever to have accessible tools for verifying content authenticity. Our mission is to make AI detection simple, free, and available to everyone — students, educators, publishers, marketers, and curious readers alike.
We analyze writing patterns — including sentence structure, vocabulary diversity, repetition tendencies, and stylistic markers — to estimate the likelihood that text was AI-generated. Our detection engine evaluates over 50 linguistic features and compares them against known patterns from major AI models.
All analysis happens in real time. Your text is processed securely and is never stored on our servers.
AIGC Check is built by a small team of engineers and researchers who study automated writing and how to read it more carefully. Our backgrounds span computer science, applied linguistics, and publishing — so we approach the problem both technically and from a reader's perspective.
We built this tool because we wanted something practical we could use ourselves in our daily work — reviewing drafts, checking submissions, and understanding how language models produce text. Instead of presenting only a percentage and a claim, we try to show what the analyzer actually noticed, so you can make up your own mind.
