If schools, periodicals or academic institutions require the use of PaperAsk to check duplicate, then it is reliable and accurate. PaperAsk is a cost-effective paper duplicate checking system, which can quickly and accurately detect the repetition rate and similarity of papers by using advanced algorithms and large databases.

However, it should be noted that different duplicate checking software has different databases and algorithms, so even a reliable duplicate checking system may have certain errors. In addition, the reliability of PaperAsk also depends on the specific application scenarios and requirements.

For the first draft of the paper, it is suggested that the free duplicate checking software of paper series such as paperfree, papertime and paperday can be used for testing, and for the final draft, the duplicate checking system required by the school can be used for testing. Ensure the accuracy and effectiveness of duplicate checking.
