How to use CopyFind
- 1The free limit of 300 words is suitable for random checks; for long articles, it is recommended to check key paragraphs section by section instead of uploading the entire text.
- 2The plagiarism check results only indicate the degree of similarity to web pages; whether it constitutes plagiarism still requires manual judgment of the source and timing.
- 3The AI detection score is a probabilistic result and should not be used as the sole basis for a conclusion; it is best combined with records of the writing process.
- 4The official website states that uploaded documents are not saved, and when dealing with unpublished manuscripts, it is still recommended to confirm the privacy policy before uploading.
- 5Plagiarism checking and AI content detection are run on two separate pages. Perform plagiarism checks first and then view the AI score. Judging the two results separately makes it clearer.
- 6If you suspect a passage was copied from a specific site, use the official target site comparison feature for targeted verification, which is more accurate than a full-web comparison.
- 7It is more stable to convert the document to plain text before uploading; the official website lists supported formats as txt, pdf and docx.
- 8The free quota and paid packages may be adjusted; please recheck the official website description before long-term use.
