What is Plagiarism Detection?
Plagiarism detection is the process of identifying similarities between two or more texts to check for unauthorized copies. The tool uses text comparison algorithms to calculate a similarity index.
How does it work?
We use two main methods:
🔤 Jaccard Index
Compares sets of unique words. Measures how many words are common between the texts.
📊 Bigram Analysis
Compares sequences of two consecutive words. Detects copied phrases and structures.
Use Cases
- Academic: Check student assignments
- Journalism: Compare articles and sources
- SEO: Identify duplicate content
- Legal: Compare contracts and documents
- Authorship: Verify originality before publishing
- Research: Find related works

Limitations
⚠️ This tool only compares two texts directly. For complete plagiarism detection on the internet, you would need specialized services like Turnitin, Copyscape or Grammarly that search millions of online sources.
💡 Tip: Use this tool to compare document versions, check text rewrites or compare student assignments against each other.
