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.
Copyscape
Copyscape checks web pages and newly written human- or AI-generated content for plagiarism and duplicate text found online. Its free checker scans a URL and presents a word-by-word comparison of results, but shows no more than 10 search results and limits scans per website. Premium accepts pasted text as well as PDF and Word uploads for originality checks. Its Batch Search can process up to 10,000 pages in one operation, with each page billed like a regular search. The Premium API can automate plagiarism and AI checks and return results in JSON, XML, or HTML; a WordPress plugin supports checks in a WordPress workflow. Premium users can create a private index of their own content, accessible only through their Copyscape account. Copysentry monitors selected pages daily or weekly and emails alerts when it finds copies. Enterprise can be hosted on-premises or in a private cloud. Copyscape says it uses Google for search and then processes results with proprietary algorithms. It warns that AI detector results may misclassify human or AI text and should not be the sole basis for disciplinary action.
