What PlagiarismSearch is
PlagiarismSearch checks submitted text against selected web, archived, publication, academic and enabled organizational sources. Its reports point out matching and similar passages, connect them to detected sources and provide a similarity report. A separate AI writing feature gives probability indicators for the whole text and individual passages, highlighting passages for review. The site also lists paper analysis, readability checking, and spelling and grammar checking.
The maker says its academic database contains over 500 million indexed texts. A free check covers up to 150 words, and registered users can check up to 300 words daily for free. Integrations include a Moodle plugin, a Google Docs add-on, a customizable API, and Viber and Telegram bots. The maker describes Moodle as its main LMS integration focus and says the API suits high-volume organizations such as schools, universities, colleges and publishing businesses. PlagiarismSearch presents the service for students, educators, writers, bloggers, universities and organizations. The Light (Basic Package) costs $9.95, paid once for one plagiarism submission and one AI submission. The maker says uploaded documents are not stored; reports may remain in an account and can be permanently deleted by the user.
