Cross-language plagiarism detection identifies content that has been translated from one language to another, helping catch plagiarism attempts where text is copied and translated to avoid detection.

This document provides information about the languages supported by Copyleaks for cross-language scans. The language codes are provided in the `ISO-639-1` standard.
