Our AI detector tells you how likely a piece of writing was generated by AI — and unlike a tool that returns a flat score, it shows you why. This free AI checker analyzes every sentence for linguistic patterns common to ChatGPT, GPT-5, Claude, Gemini, and other large language models, then highlights the exact passages that triggered each flag. Paste text or upload a PDF — no login required to start.
How well does it handle text that's been paraphrased or run through a spinner, does it still flag those as AI?
sentence-level highlighting is such a practical move, going beyond just a percentage score and actually showing you where the AI flags land is super useful for editing.
Pasted in a mix of my own writing and some GPT output and it actually flagged the right sentences instead of just slapping a percentage on it. Uploaded a pdf too and it handled it without weird formatting glitches.
The sentence-level highlighting is genuinely useful instead of just throwing a number at you. Surprised how well it flagged a few mixed paragraphs in my own writing.
the sentence-level highlighting is genuinely useful — way more actionable than a vague percentage. love that it works across the major models too.
Sentence level highlighting is a nice touch since most tools just give you a number. One thing I'd love to see is a confidence percentage on each flagged sentence so I know when to double check versus when it's clearly AI generated.
How does it handle text that was heavily edited after AI generation, like when someone rewrites most of it themselves? Curious if it still flags it as AI or gives partial credit.
