Common questions

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

No, TextMaster is better for that. You can just paste the essay into TextMaster's web tool and get a heatmap. TextCortex requires coding to send the text via API.

Can I use either tool on my phone?

Neither has a mobile app. TextMaster's website works on a phone browser but is clunky. TextCortex cannot be used on a phone at all without writing code.

Which tool is cheaper for checking 10,000 words per month?

TextMaster would cost $350 per month at $0.035/word, which is very expensive. TextCortex's pricing is hidden, but it's likely cheaper at scale if you negotiate an enterprise plan.

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

TextCortex explicitly says it detects multiple models and updates frequently. TextMaster focuses on linguistic patterns and works well for ChatGPT-style text but may miss newer models.

Which tool is easier for a non-technical person to start using today?

TextMaster. You sign up, go to the AI Detector tool, paste text, and click analyze. TextCortex requires reading API docs and writing code.

TextMaster wins for everyday users with its simple web tool; TextCortex is only for developers who need automated bulk detection.

If you just want to quickly check if a piece of writing is AI-generated without any hassle, go with TextMaster — it's simple, visual, and works in your browser.
