What is Plagiarism Checker?
A plagiarism checker is an essential tool for writers, educators, and SEO professionals. It scans your text and compares it against a massive database of published web pages, academic papers, and articles to identify identical or highly similar phrases.
How Does Plagiarism Checker Work?
The tool breaks down your text into smaller chunks (n-grams) and queries a real-time database to find exact or fuzzy matches. It then calculates a similarity percentage based on the amount of matched text versus original text.
How to Use This Tool
1. Paste your text into the input area. 2. Click 'Check for Plagiarism'. 3. Wait for the scan to complete. 4. Review the highlighted text and similarity score.
