Grammarly Plagiarism Checker
Verified working Sep 22, 2026
Checks essays for copied text while flagging writing and citation issues.
Grammarly’s plagiarism checker lets users paste or upload a document and scan it for potential copied passages. It pairs originality checking with Grammarly’s broader writing feedback, including grammar, readability, word choice, citation formatting, and AI-use disclosure guidance.
Why it stands out
- Combines plagiarism detection with full writing revision feedback instead of treating originality as a separate step.
- Includes citation-format checks for common academic styles such as APA, MLA, and Chicago.
- Can flag both plagiarism concerns and AI-use disclosure issues, which is useful for academic integrity workflows.
- Part of Grammarly’s broader ecosystem across web, desktop, mobile, and browser-based writing surfaces.
Good to know
- Source matching is described around web pages, so it may not cover every paywalled, private, or institution-only database.
- Some advanced Grammarly capabilities may require signing in or using a paid Grammarly plan.
- The page is aimed mainly at essays, papers, articles, and documents rather than code, multimedia, or specialized scholarly datasets.
