HOW IT WORKS
Quetext's DeepSearch™ technology understands context, word placement, and sentence structure to catch all forms of copying and plagiarism. The AI Detection engine goes a step further, identifying text that may have been generated by major LLM tools like ChatGPT or Gemini and giving you a clear probability score.
Results are displayed through ColorGrade™ Feedback, which visually distinguishes exact matches, near-matches, and AI-flagged passages so you can review everything side by side.
Quetext also checks your grammar as you write, supporting 6 dialects of English and 9 additional languages. Paid plans include bulk file upload.
