Dolos

Dolos is a source code plagiarism detection tool for programming exercises. Dolos helps teachers in discovering students sharing solutions, even if they are modified. By providing interactive visualizations, Dolos can also be used to sensitize students to prevent plagiarism.

Dolos aims to be:

Easy to use by having minimal installation instructions and an intuitive user interface

Dolos is a command-line (CLI) tool that analyses source code files for similarities between them. It is able to show an interactive user interface in your browser by launching a local webserver. The analysis results are available in machine readable CSV files and Dolos can be integrated as a JavaScript library in other applications empowering users to integrate plagiarism detection in their personal workflow.
