Common questions

Is Copyleaks better than TextCortex AI Content Detector API for checking student essays?

Yes, Copyleaks is better for that. It has a simple web interface, supports PDF and Word uploads, and integrates with learning management systems. TextCortex requires programming and is meant for developers.

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

No. Neither tool has a mobile app. You can access Copyleaks through a phone browser, but TextCortex is an API that requires coding — you cannot use it directly on a phone.

Which tool is more accurate at detecting AI-generated text?

Both claim high accuracy. TextCortex may have an edge because it updates frequently to catch newer AI models, but Copyleaks is also highly rated. For most everyday users, the difference is small.

Do I need to know how to code to use Copyleaks?

No. Copyleaks is designed for non-technical users. You can upload files or paste text directly on their website. TextCortex, on the other hand, requires you to write code to use its API.

Which tool is cheaper for a small business?

It's hard to say because neither publishes clear pricing. Copyleaks uses a credit system that may be simpler for occasional use. TextCortex's credit costs can add up quickly if you scan many documents, and you must contact sales for enterprise plans.

Copyleaks wins for everyday users with its simple web interface and LMS integrations; TextCortex is a developer-only tool for those who need to build custom AI detection at scale.

If you just want to paste a document or essay and get a clear answer, go with Copyleaks — it's ready to use right now. If you're a developer who needs to build your own detection system, TextCortex's API is the more flexible choice, but be prepared to write code and manage credits.
