PlagAware vs Proofademic

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.

Proofademic analyzes submitted writing for AI-generated content and plagiarism, producing an overall score and sentence-by-sentence breakdown. Its listed checks include AI text, ChatGPT, paraphrase, multilingual and plagiarism detection, as well as Batch Scan. Proofademic says it reviews essays, research papers, articles and reports in 23 languages, with model coverage including ChatGPT, GPT-5, Claude and Gemini. Batch Scan lets teams upload documents, sort results by risk, inspect sentence-level evidence and export reports. Developers and platforms can use the AI Image Detector API; a browser-based image detector for individual users is described as coming soon. Proofademic says submitted text is processed automatically, is not used for model training or resale, and is not reviewed by people. It reports a 0.2% document false-positive rate in an evaluation of 4,200 fully human-authored academic texts, while advising that results support human review. The Free plan is free and includes 1,000 words and a 3-day trial. Paid plans are $15 a month for Essential, $25 a month for Premium and $45 a month for Professional.
