Common questions

Is DupliChecker AI Detector better than TextCortex AI Content Detector API for checking my homework?

Yes, DupliChecker is much better for homework. You just paste your text or upload a file and get a result. TextCortex requires programming knowledge and is meant for developers, not students.

Can I use TextCortex AI Content Detector API on my phone?

No. TextCortex is an API for developers — there is no mobile app or mobile-friendly website. DupliChecker also has no mobile app, but you can use its website on a phone browser, though it's not ideal.

Which tool is more accurate at detecting AI writing?

TextCortex is likely more accurate because it updates frequently to catch newer AI models and provides detailed heatmaps. DupliChecker can give false positives on well-structured academic text.

Do I need to pay for either tool?

DupliChecker has a free tier with ads and limits. TextCortex does not clearly publish a free tier — it's aimed at businesses and developers who pay for credits. For occasional use, DupliChecker's free version may be enough.

Can I check a PDF with both tools?

DupliChecker lets you upload PDF, DOC, DOCX, and TXT files directly. TextCortex accepts PDF and DOCX as input, but you need to send them via an API call, which requires coding.

DupliChecker wins for regular folks who need a quick, no-code AI check; TextCortex is for developers only.

If you just want to paste some text and find out if it's AI-written, go with DupliChecker AI Detector — it's free to start, works in your browser, and also checks for plagiarism. Skip TextCortex unless you're a developer building a custom tool; it's powerful but not designed for everyday people.
