Turnitin vs Grammarly Plagiarism Checker: Which One Should You Trust?
Grammarly's plagiarism checker is a convenient add-on for writers. Turnitin is the tool universities use to catch academic misconduct. They sound similar; they are not the same. Here is a plain comparison so you know which to trust before submitting.
Coverage: what each tool searches
Grammarly scans public web pages and ProQuest's academic database. Turnitin scans the open web, 1.9+ billion previously submitted student papers, paid journal databases, and premium publisher content. If your source is from another student's assignment, Grammarly will not see it.
Report format
Grammarly gives you a similarity percentage inside its editor and highlights matching text. Turnitin gives you a formal PDF report with per-source breakdown, color bands, and match confidence — the same document universities produce for internal review.
When each is enough
Grammarly is enough if you are checking a blog post, marketing copy, or a first draft for accidental copying. Turnitin is the answer whenever a university, journal, or publisher will require an official report.
Cost
Grammarly plagiarism check requires Grammarly Premium (~$12–30/month). Turnitin accounts are institutional and not sold to individuals — that is why students order single Turnitin checks through services like FREKUM WRITES for $1.3.
FAQ
Will Turnitin catch what Grammarly missed?
Usually yes. Turnitin's student paper database is the biggest gap in Grammarly's coverage.
Does Grammarly report to my university?
