First of all, it has to be said that it is a leader in the field of paper duplication checking. HowNet duplicate checking and scientific name duplicate checking are both academic misconduct detection systems, which are the most authoritative paper detection systems at present. It cooperates with 90% universities in China. Many schools take the final duplicate checking result of HowNet as their students' paper scores, but HowNet is not open to individuals, and only cooperates with universities, scientific research institutions and magazines.

Wanfang paper duplicate checking system is also a good paper duplicate checking system, which is open to individuals. However, due to the existence of HowNet, Wanfang paper testing is basically used to copy the first draft of the paper. Especially the price is more favorable.

VIP paper duplicate checking system is similar to Wanfang system, which is a good platform for duplicate checking of papers with the same preferential price and is suitable for duplicate checking of the first draft of papers.

HowNet, Wanfang and Weipu are the better platforms for paper duplication checking in China at present, and of course they are also other platforms for paper duplication checking, but they are not as good as these three platforms.
