About Plagiarism Checker
A free online tool to detect plagiarism by comparing text against billions of web pages. It supports multiple file formats, provides sentence-wise results with source links, and offers paid plans for higher word counts and API access.
SmallSEOTools Plagiarism Checker is a widely-used online tool designed for students, teachers, writers, and SEO professionals to ensure content originality. It operates on a freemium model, offering a free version that allows users to check up to 1,000 words per search by pasting text or uploading files from local storage, Google Drive, or Dropbox. The tool compares submitted text against billions of web pages, providing a detailed report with percentage scores for unique and plagiarized content, and highlights matching sentences with links to the original sources. For users with more extensive needs, SmallSEOTools offers paid monthly and annual subscription plans that increase the word count limits significantly and provide access to a plagiarism checker API and a WordPress plugin. An enterprise-level plan with custom pricing is also available for larger organizations and learning management systems (LMS). The platform supports over 25 languages and is accessible from any web browser without requiring software installation.
