Our plagiarism checker analyzes your text using advanced algorithms that detect duplicate content patterns, spun text, and similar phrases. It compares segments of your text against a database of common phrases and provides a similarity score.
Never! All processing happens entirely in your browser (client-side). Your text never leaves your device, and we don't have any servers that store your content. This ensures complete privacy and security.
We support plain text (.txt), Microsoft Word (.doc, .docx), and PDF files up to 5MB. You can also directly paste text into the input area.
Our tool provides a reliable similarity score based on pattern matching and common phrase detection. While it's excellent for quick checks, for academic or professional submissions, we recommend using it as a preliminary screening tool.
For optimal performance, we recommend texts between 50 and 5000 words. Very long texts may take longer to process but are still supported.
