Common questions

Is AI Detector by 5Tools better than TextCortex AI Content Detector API for checking a student essay?

Yes, for a single essay, 5Tools is much better because you can paste the text and get a heatmap instantly without signing up. TextCortex requires coding and API setup, which is overkill for one document.

Can I use either tool on my phone?

No. Neither tool has a mobile app. 5Tools can be used on a phone's browser but the interface is not optimized for small screens. TextCortex is an API, so you'd need to build a mobile app yourself.

Which tool is cheaper for a small business?

5Tools is cheaper for occasional use because it offers free daily scans. TextCortex has no free tier and requires contacting sales for pricing, so it's likely more expensive and only worth it for high-volume needs.

Do these tools detect AI content from ChatGPT, Claude, and Gemini?

TextCortex explicitly updates frequently to detect newer models like GPT-4o. 5Tools claims 'bypass-aware detection' but may struggle with very recent models. Neither guarantees 100% accuracy.

Can I upload a PDF to either tool?

Yes, both accept PDF uploads. 5Tools also accepts DOC and DOCX files. TextCortex additionally accepts JSON and HTML inputs.

AI Detector by 5Tools wins for everyday users with its no-fuss web interface; TextCortex is for developers who need scalable, multilingual detection.

If you just want to paste a piece of text and see if it's AI-written, start with AI Detector by 5Tools – it's free, fast, and doesn't require an account. If you're a developer or run a content factory that needs automated, multilingual scanning, TextCortex is the right choice, but be ready for a technical setup and a sales call for pricing.
