What is Turnitin?

Turnitin is a tool for detecting plagiarism by scanning student submissions against an extensive academic works, publications, and web content database. This service seamlessly integrates at Cornell into Canvas, the institution's Learning Management System.
Why Use Turnitin?
Cornell students must uphold academic integrity, and Turnitin assists in this endeavor. It is a learning tool to help students properly reference and cite their sources.
Considerations for Using Turnitin
Turnitin is designed for educational purposes. While primarily used to detect plagiarism, instructors can choose not to use the similarity detection features. They prefer to use Turnitin Assignments to access Rubrics, PeerMark, QuickMarks, and Feedback Studio.
Instructors should inform students that their papers may be submitted to Turnitin for plagiarism detection. Papers will become part of the Turnitin database for future reference. Instructors can exclude student work from the repository, meaning it won't be available for future comparisons.

Grammarly vs Turnitin: Detailed Comparison

1. Purpose and Core Functionality: Different Tools for Different Needs
Grammarly is a writing assistant that enhances grammar, punctuation, tone, clarity, and style. Its plagiarism checker, available in the premium version, is a secondary feature. Turnitin is a tool for academic integrity, focusing on plagiarism detection and originality in academic submissions. It doesn’t improve writing quality.
2. Plagiarism Detection Capability: Who’s Better at Catching Copycats?
Turnitin excels in plagiarism detection. It compares submissions against a vast database of academic papers, student work, journals, and more, allowing it to catch subtle plagiarism. Grammarly checks against billions of web pages but lacks access to scholarly databases, making it better suited for non-academic content.
3. Writing Assistance and Grammar Checking: Grammarly’s Playground
Grammarly offers comprehensive grammar, punctuation, spelling, conciseness, clarity, tone suggestions, and feedback tailored to specific writing styles. Turnitin doesn’t provide grammar checking or writing improvement features and focuses solely on plagiarism detection.

This makes it versatile for various users. Turnitin is primarily accessible through educational institutions, integrated with learning management systems, and designed for educators and administrators.
5. Accuracy and Detection Methodology: Digging Deeper into How They Work
Turnitin’s strength lies in its sophisticated detection algorithms and access to vast academic content. It uses semantic analysis and proprietary techniques to catch paraphrased plagiarism. Grammarly detects exact matches and some paraphrased content, but semantic recognition isn’t as advanced.
6. Report Quality and Use Cases: What You Get from Each Tool
Turnitin generates detailed similarity reports with percentage scores, matched sources, and links, helping educators assess academic honesty. Grammarly’s reports are simpler, showing a percentage of matching text and linked sources, which is suitable for avoiding duplicate content in non-academic writing.
7. Availability and Pricing: Who Can Get Their Hands on These Tools?
Grammarly is available to individual users, offering a free, premium version with advanced features. It’s ideal for students, writers, marketers, and professionals. Turnitin isn’t available to individuals directly; institutions must subscribe. It’s priced higher and usually accessed through schools, colleges, and universities.
8. Suitability by User Type: Who Benefits Most from Each Tool?
Students can use Grammarly to enhance their writing skills, while Turnitin is crucial for academic submissions. Teachers and institutions need Turnitin to monitor academic integrity. Professionals and writers benefit from Grammarly by improving their writing and avoiding unintentional plagiarism. Researchers find Turnitin, or its iThenticate version, better for research submissions due to its deeper plagiarism detection.

Why Traditional Tools Fall Short
When you hear “Grammarly vs Turnitin,” you think of grammar checks and plagiarism detection, right? But that’s not enough. These tools don’t help with the deluge of data.
