In their own words
Dolos
Dolos is a free, open-source tool for finding similarities between source-code submissions, particularly for teachers reviewing tests, exams, and exercises where collaboration may be allowed in small groups. Its analysis process tokenizes files, fingerprints token sequences, indexes matches, and produces reports. For each file pair, reports include similarity, total overlap, and the longest matching fragment. Dolos uses Tree-sitter parsers and supports languages including Bash, C, C++, C#, Elm, JavaScript, Java, PHP, Python, and TypeScript. The web app accepts ZIP files and detects languages from file extensions; in mixed-language archives, it analyzes only the dominant language unless a language is selected. Its public API accepts ZIP submissions up to 10 MB, with the CLI or library recommended for larger submissions. Analyses can also run locally, with results displayed in a browser, or on a self-hosted server. The free web app is hosted on Ghent University servers in Belgium. Dolos provides a JSON API for integrations such as Dodona and lists CSV as a report export format.
PlagAware
PlagAware is a plagiarism search engine for educational institutions, businesses, and individuals. Its FullScan technology checks submitted text against more than 70 billion online documents and user-provided comparison texts, while text monitoring can flag potential copying or duplication on texts and web pages. An AI detector looks for stereotypical language associated with systems such as ChatGPT, Copilot, Gemini, and LLaMA; PlagAware says it does not send data to those external providers. Reports can be edited interactively, downloaded as PDFs, and shared through permanent links. Users can paste text, upload TXT, RTF, HTML, DOC, DOCX, ODT, and PDF files, or submit through the API. The web application works in supported modern browsers without workstation installation and offers integrations for Moodle, SharePoint, Joomla, WordPress, and Blogger. It accepts texts up to 750,000 characters, files up to 15 MB, and up to 50 parallel uploads. A significant coverage limit is that it does not access non-public sources such as paid scientific journal articles or paid portal content. Plans include free use, subscriptions, and prepaid credits; Subscription Light is €2.99/month with a six-month minimum term.
