In their own words
Codequiry
Codequiry checks submitted source code for plagiarism and AI-generated code, helping educators verify that student work is their own. It compares submissions with peer work, web sources, and historical material. The company says more than 20 analysis engines examine code structure and logic, not just textual matches, and that the system flags code associated with ChatGPT, GitHub Copilot, Claude, and Gemini. It supports more than 65 programming languages, including Python, Java, C/C++, JavaScript, C#, Go, and Rust. Instructors can review similarity scores and side-by-side matches, with matching lines highlighted. Grow includes a web dashboard, desktop client, and API/CLI access; all three listed plans include unlimited MCP calls. Advanced includes LMS integrations, while Scale offers custom LMS and SIS integrations built to spec. The pricing page states FERPA and GDPR compliance, SOC 2 Type II certification, TLS 1.3 encryption, and AES-256 encryption at rest. Uploaded code on plans without Rapid may be retained indefinitely in an anonymized comparison corpus and cannot be deleted on request. Grow costs €25.76 a month; a one-day trial is available and there is no free plan.
Noplag
Noplag is an open-source plagiarism checker with a hosted cloud service and an engine released under Apache 2.0. Its current matching uses winnowing fingerprints and live-web comparison to find verbatim and near-verbatim copying; it does not detect paraphrase. Sources include the open web, Common Crawl, Wikipedia, academic indexes, the Noplag Database and users’ own folders. Submit DOCX, PDF, TXT, ODT or RTF files, paste text or provide a URL. Reports link matches to their sources, display similarity scores and exact overlapping text, and can be exported as PDFs. Detection is calibrated at launch for English, Spanish, Portuguese, Polish and Ukrainian. AI-content detection is marked as coming soon and intended as a separate signal. The free plan allows three checks per month, up to 2,500 words per check, with community Discord support. Pro costs $9.99 a month and includes 50 monthly checks, up to 25,000 words per check, database and academic-index matching, REST API and webhooks, and email support. A 14-day trial is listed.
