The Turnitin Plagiarism Checker is a web-based tool that compares your written work against:

• Billions of internet pages

• Academic journals and books

• Previously submitted student papers

• AI-generated content (Turnitin AI detection)

It provides a Similarity Report, which shows the percentage of your content that matches existing sources, identifies potential plagiarism, and highlights improperly cited content.

Once you upload a document to Turnitin, it scans your text using advanced algorithms and cross-checks it with its extensive database. Within minutes, it generates a detailed Similarity Index report that shows:

• The overall similarity percentage

• Potential AI-written segments (new feature)

• Citations and quotation accuracy

Turnitin also offers grammar feedback and citation assistance for institutions using its advanced grading tools.

📊 Understanding the Turnitin Similarity Report

Turnitin’s Similarity Report uses a percentage score to indicate how much of your content matches existing sources.

• 0–10%: Excellent. Content is mostly original.

• 11–25%: Acceptable with proper citation.

• 26–40%: Needs revision — review citations or reword.

• Above 40%: High risk of plagiarism — rewrite required.

The report also breaks down which sources your work matches and highlights the exact sections that may need improvement.

• Use your own words – Don’t just paraphrase, understand and rephrase.
