How to use PaperYY
- The plagiarism check results only reflect the overlap with the comparison database and do not represent the official testing conclusions of the university or journal.
- the results are for reference only.
- Before the final check, confirm the system specified by the school.
- There may be differences between third-party results and the official system, so a margin should be reserved.
- You must read through the text after intelligent simplification.
- machine rewriting may lead to incoherent sentences or semantic deviation, and manual revision is required.
- The official promise of a refund for unsatisfactory results is subject to applicable conditions.
- please check the applicable versions and criteria before placing an order.
- Stick to the officially announced URLs to avoid visiting fake websites, which may lead to irreversible consequences such as thesis leakage.
- In addition, it should be specially noted that the output of AI detection is a "probability judgment" rather than a final conclusion: misjudgments are not uncommon in scenarios such as short texts, dense professional terms, or texts that have been deeply rewritten manually, and it is not recommended to use it as the sole basis for academic misconduct or content violations.
