Abstract
This research aimed to compare the effectiveness of iThenticate and Turnitin in plagiarism detection, focusing on the analysis of accuracy and precision in detecting similartity. Various types of documents downloaded from online databases, Thai and English theses, as well as content generated by AI were used for testing and comparison of similarity scores detected by both programs. The findings revealed that Turnitin provided higher accuracy particularly when Student Paper Database was included, giving Turnitin a broader detection scope. However, both softwares exhibited similar precision. Regarding AI-generated content detection, both softwares could partly identified AI-generated text in English documents but were unable to detect AI-generated content in Thai documents. This research can serve as a guideline for selecting appropriate plagiarism detection software for academic institutions.
