Paperyy and paperpass have their own advantages. At the same time, Paperday's weight checking speed is faster, and the detection accuracy rate is over 99%. Its detection principle is to adopt the self-developed dynamic fingerprint leapfrog scanning technology, and the fingerprint comparison database consists of more than 90 million academic journals and dissertations, as well as an Internet webpage database with the number exceeding 654.38+0 billion.

However, the accuracy of duplicate checking results depends not only on the tools used, but also on the individual's use skills and the originality of the paper. Therefore, we can't give a clear answer to the question of which duplicate checking result is more accurate, PaperYY or PaperPass.

In addition, the result of duplicate checking is not the only criterion to judge the quality of the paper, but also needs to be comprehensively evaluated from the aspects of academic nature, rigor of discussion and research depth. Therefore, it is suggested that more accurate results can be obtained by combining various methods when using the duplicate checking tool.

Generally speaking, these two tools have their own characteristics, and which one is better depends on personal needs and actual situation.
