Code similarity checker is a tool that helps determine how similar students' code is. It does not automatically detect plagiarism but rather shows you how similar two programs are to one another. Similarity checkers assist in identifying code reuse or code similarity between projects, ensuring compliance with open-source licenses and avoiding licensing conflicts.

This method involves breaking down the code into individual tokens such as keywords, variables, and operators. The checker compares code snippets against a database of known code sources, such as open-source projects or academic publications, to detect potential instances of plagiarism.

The Code similarity detector serves as a valuable asset for software developers, educators, and researchers by helping them identify duplicate or similar code segments. The primary purpose of a code similarity checker is to assist in detecting code plagiarism, where developers copy or reuse code without proper attribution or authorization.
