GPTOne
Free AI detector for ChatGPT, Claude, Gemini & more
GPTOne is a free AI content detector that instantly spots text written by ChatGPT, Claude, Gemini, and other major AI models. Paste your text and get fast, reliable results in seconds. It's more than a detector, though GPTOne bundles a grammar checker and a humanizer (Soon), and a word counter into one clean workspace, so you can check and polish your writing without juggling five different tools. 16+ languages supported, including Italian, Spanish, French, and Chinese.
Hey Product Hunt! 👋
I built GPTOne because AI-generated text is everywhere now, and telling what's human-written from what's not has become genuinely hard for teachers, editors, recruiters, and anyone who cares about authentic content.
GPTOne detects content from ChatGPT, Claude, Gemini, Deepseek, and other major models in seconds. But I didn't want it to be just a detector, so it also comes with a grammar checker, a humanizer (sooner), and a word counter everything you need to check and polish writing in one place.
A few things I'm proud of:
🔍 Fast, reliable detection across all the major AI models
🌍 Support for 16+ languages (English, Italian, Spanish, French, Chinese, and more)
✍️ A complete toolkit, not just a single feature
🆓 Free to start no wall before you can try it
I would love your honest feedback, and I'll be around all day to answer questions and hear what you'd want next.
Thank you for checking it out! 🙏
