It's good. The paper has fast detection speed and is easy to modify. It usually takes 3 to 5 minutes to generate duplicate detection reports, and online real-time duplicate checking is supported after detection is completed. At present, 99% of colleges and universities adopt the detection system of HowNet, but the price of HowNet has soared. We can use paperwin to check the first draft of the paper, or we can modify the paper online and build our own library. It is a good tool to assist the revision of papers.
