Common questions

Is Originality.ai better than TextCortex AI Content Detector API for a non-technical person?

Yes, absolutely. Originality.ai is designed for non-technical users with a simple dashboard and Chrome extension. TextCortex requires you to write code and handle API responses, so it's not suitable for regular people.

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

No. TextCortex has no mobile app and no user interface at all. You would need to build your own app or website to use it on a phone.

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

Both claim high accuracy, but Originality.ai is specifically praised for GPT-4 and Claude detection. TextCortex has an edge for multilingual text. For English content, Originality.ai is more reliable for everyday use.

Is Originality.ai worth the price for a student?

Probably not. At $12.95/month or $30 one-time for credits, it's expensive for occasional use. A student would be better off with a free tool like GPTZero or a built-in plagiarism checker from their school.

Can I scan a whole website with TextCortex AI Content Detector API?

Yes, but only if you write code to crawl the site and send each page's text to the API. Originality.ai has a built-in 'Website Scan' feature where you just enter a sitemap URL.

Originality.ai wins for everyday users with its simple dashboard and Chrome extension; TextCortex is only for developers who need multilingual detection at scale.

If you're a regular person who just wants to check if something was written by AI, go with Originality.ai—it's easy, has a clear price, and works right in your browser. Skip TextCortex unless you're a developer building your own tool. For most people, Originality.ai is the practical choice.
