Grammarly vs Turnitin: Which Is Accurate?

Let’s examine how effectively each platform performs its core function whether that’s detecting plagiarism or identifying writing issues that need correction.

Accuracy of Grammarly

Grammarly’s plagiarism detection scans 16 billion web pages but may miss some copied content, particularly from academic sources. The tool excels at catching common errors but isn’t foolproof for detecting complex plagiarism.

Its grammar and style suggestions are generally reliable for everyday writing, though it occasionally flags correct usage in creative or technical contexts. Grammarly is better for improving overall writing quality, grammar, punctuation, and spelling errors. 

Accuracy of Turnitin

Turnitin boasts exceptional accuracy with its 99 billion-page database, including academic journals and student papers. It identifies even minor similarities and highlights matched content with color-coded sources.

However, it can generate false positives for common phrases, proper citations, and widely used terminology. Its strength lies in comprehensive academic plagiarism detection rather than writing quality assessment. 

Turnitin is more effective than Grammarly for plagiarism detection quality, as it can easily spot text alterations and has access to extensive databases.

The accuracy depends on your specific needs rather than overall superiority.

Grammarly vs Turnitin: Which Is Easy To Use?
