Frequently asked questions
Which AI content detection tools are completely free?
AI Scanner, DetectMy, Detector.io, and GPTVerify are all completely free with no sign-up needed. ZeroGPT has a free plan but its paid tiers have no clearly published prices. TraceGPT gives one free page and then requires payment. AI Image Detector is the only tool here with no free option at all.
Which tool gives the most detail about why text was flagged?
GPTVerify stands out for this: it gives sentence-level results and clear explanations of why each section was flagged, not just a score. AI Scanner and DetectMy also highlight suspicious sentences. Detector.io shows a score and highlights risky sections but focuses more on speed than explanation.
Can any of these tools check AI-generated images?
Only AI Image Detector does this. It cross-checks four independent detection models and gives graded conclusions with evidence rather than a single percentage. It supports batch processing of up to 50 images. Every other tool here checks written text only.
Which tool works for academic or institutional use?
TraceGPT is the one built for that setting. It claims 97% detection accuracy, connects with learning management systems and other platforms, and produces downloadable reports. Free use is limited to one page; institutional plans require contacting sales for a price.
Do any of these tools check for plagiarism as well as AI writing?
ZeroGPT includes a plagiarism checker alongside its AI writing detection. TraceGPT is the only tool listed under plagiarism prevention specifically. The other tools - AI Scanner, DetectMy, Detector.io, and GPTVerify - focus on detecting AI-written patterns in text and do not include plagiarism checking.
