In their own words
Originality.ai
Originality.ai provides tools for checking AI-generated text, plagiarism, facts, readability, grammar, spelling and content quality. Its free Basic plan costs $0.00 per free and provides three AI scans per day, with up to 2,000 words per scan. The AI detector offers configurable allowances of 0%, 5%, 15%, 25% or 40%. A website scanner can crawl a site, identify pages likely to contain AI-generated content and run scheduled scans. The browser extension scans Google Docs, web pages or selected text, and includes writing replay, typing behavior insights and shareable reports. A REST-based API submits text for AI and plagiarism scans and returns detailed results; the maker says AI detection supports 30 languages. API AI scans require at least 50 words, and the help page says accuracy decreases below 100 words. Originality.ai describes detection results as probabilistic estimates that may produce false positives or false negatives, not conclusive proof. Pro costs $12.95 per month billed yearly, with a monthly option at $14.95 per month. The service is available through web, API and extension.
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.
