PlagTracker is a Ukrainian-based online plagiarism detection service that checks whether similar text content appears elsewhere on the web.

[7][8] For using, the program may take more time to develop a report based on the length of the paper and the amount of plagiarized content.

[9][10] PlagTracker also provides a premium service which allows the user to upload documents instead of copying and pasting text.

[11] PlagTracker uses a proprietary algorithm to scan a given document and compare it to the content sources across a database of academic papers, and the Internet.

[3] It is multilingual (English, French, German, Spanish, Romanian) though the algorithm also analyzes any Latin or Cyrillic symbols.
