What Scribbr Plagiarism Checker is
Scribbr Plagiarism Checker is a web service for comparing academic work with online and published sources. Its free report gives a plagiarism risk assessment and the top matching sources. A paid report adds a similarity percentage, source matches, document view, side-by-side comparison, private uploads, writing corrections, and an AI Detector report. The checker accepts DOC, DOCX, PDF, and ODT files, supports 20 languages, and can export reports as PDF. Its citation generator can help cite highlighted text in APA, MLA, and Chicago styles. Scribbr says its database covers more than 99.3 billion current and historical webpages and 8 million publications from over 1,700 publishers. Documents are not stored in a public or shared database, are removed after one year, and can be deleted sooner after the report. Checks cost 19.95 USD once for up to 7,499 words, 29.95 USD once for 7,500–49,999 words, or 39.95 USD once for 50,000+ words.
