First of all, PaperPass uses a variety of algorithms and databases in duplicate checking, including data comparison with authoritative duplicate checking systems such as HowNet, to ensure the accuracy of its detection results. In addition, PaperPass also provides detailed duplicate checking report and modification suggestions, which is convenient for users to modify and polish the paper.
However, because the algorithm and database of PaperPass are different from authoritative duplicate checking systems such as HowNet, the detection results may be different from these authoritative systems. In addition, the free version of PaperPass may be limited in the number of repeated papers and the number of words per day, with relatively few functions, such as not supporting online editing and charging for downloading reports.
To sum up, if the school uses authoritative duplicate checking systems such as HowNet, in order to ensure the accuracy of the results, it is recommended to use the same duplicate checking system as the school. If the school does not specify what kind of duplicate checking system to use, it can use PaperPass to check the first draft, and combine with other free duplicate checking software to check the duplicate several times to improve the originality and readability of the paper as much as possible.
