According to some users' feedback, the difference between Gezida and HowNet is 5% to 10%, or even more. This is mainly because their paper retrieval databases are different, and their comparison methods and algorithms are also different.
Generally speaking, which specific duplicate checking rate is high needs to be judged in combination with specific circumstances. Different duplicate checking systems have different algorithms and databases, so the duplicate checking results will be different.

And for the final draft, use the duplicate checking system required by the school to ensure that the paper meets the academic requirements.
