I used the free version, but the report seems incomplete. Does the paid version offer a more thorough plagiarism check?

Plag AI applies to organizations as it can allow for bulk uploads, generation of comprehensive reports and protection against content theft of any original work done for advertising, publishing or SEO.

In its report, Section matching is offered by Plag AI and more in-depth comparative analysis is offered in the high-end version of the report.

There are instances that scanning may be an issue due to complicated PDF files, or when the file is damaged. Consider converting the file to .docx or looking for file size constraints.

Non-English content is especially difficult to cope with when using Plag AI since the passable language is primarily English. Use tools with multi-language capability instead.

Plag AI allows for multiple document uploads, however, larger-sized files or unsupported file types may encounter challenges. Use a smaller batch or try to ensure that the files do not exceed the set limits.
