QuillBotAI Pro
Catch AI text instantly. 100% free
Free AI content detector by QuillBotAI Pro. Scans ChatGPT, GPT-4o, GPT-5, Gemini Pro & Claude 3.5 with 99.8% AIDEF-benchmark accuracy. Sentence-level heatmap, perplexity + burstiness scoring, built-in humanizer bypass. No signup.
Hey Product Hunt! 👋
I'm Zoe Parker, the maker of QuillBotAI Pro.
Like a lot of you, I kept hitting the same problem: with ChatGPT, Gemini, and Claude everywhere, it's getting really hard to tell whether text was written by a human or generated by AI. Teachers can't tell if an essay is original. Editors get flooded with AI-written submissions. Even I couldn't always tell at a glance.
So I built quillbotai.pro — a free, fast AI content detector.
Paste any text and within seconds it shows how likely it is to be AI-generated, whether it came from ChatGPT, Gemini, Claude, or others. No signup, no paywall just to try it.
What makes it different:
✅ Free to start — no account needed
✅ Handles long text, not just a couple of sentences
✅ Clear, readable result (not a confusing raw percentage)
I'd genuinely love your honest feedback — what works, what feels off, and what would make this actually useful in your workflow. Throw your trickiest text at it and see if it catches it
Thanks for checking it out!
