These duplicate checking systems are formal and professional duplicate checking platforms, which can provide accurate duplicate checking results and high-quality duplicate checking services. Therefore, the choice of duplicate checking system depends on the requirements of schools or institutions and personal needs. It should be noted that different duplicate checking systems may have different duplicate checking results for the same paper, because the algorithms and databases of different systems are slightly different.
In addition to the above-mentioned duplicate checking system, there are some other duplicate checking platforms to choose from, such as paper time. These platforms usually have a variety of duplicate checking systems to choose from, which can reduce the duplicate checking cost to some extent. However, it should be noted that when using the free or preferential duplicate checking platform, we should choose a formal platform to avoid paper leakage or other security problems.
