🧠 Introduction
Quetext began as one of the most popular plagiarism checkers on the web. Over time, it has expanded into AI detection, offering educators, writers, and students a complete content integrity suite.
In this review, we tested Quetext’s AI Detector for accuracy, reliability, and overall experience. We also explored how well TwainGPT can bypass its AI detection system.

🧪 AI Detector Accuracy
We tested Quetext on multiple writing samples to evaluate consistency and precision.
| Text Type | AI Probability |
|---|---|
| Human Text | 0% AI |
| AI Text (ChatGPT) | 99% AI |
| Mixed Text (50/50) | 16% AI |
| TwainGPT Humanized | 0% AI |
✅ The AI detector is accurate overall, correctly identifying AI-generated content without flagging human writing.
⚠️ It slightly underestimated mixed text, but that is better than overestimating and causing false positives.
🔍 Plagiarism Checker
The plagiarism checker is reliable and functional. It identifies copied or near-duplicate content from web sources.
Although testing was limited, early results suggest that it performs as expected for plagiarism detection.
💻 User Experience
The Quetext interface feels outdated, especially compared to modern tools like TwainGPT, GPTZero, or Copyleaks.
During sign-up, we encountered repeated IP and email blocking errors, even when using verified and legitimate accounts. This was frustrating and may prevent new users from getting started easily.
Once inside, however, the system runs smoothly and delivers results quickly. Reports are clearly formatted and easy to interpret.
