Plagiarism Checker
Check for plagiarism
Frequently Asked Questions
How does the plagiarism checker work?
Paste your text. The tool breaks it into phrases and searches for matches across web pages, academic databases, and published content. Results show: overall originality percentage, matched sources with URLs, and highlighted matching passages.
What percentage of originality is acceptable?
Academic papers: 85%+ original (15% or less matched, mostly quotes and common phrases). Blog content: 90%+ original. Professional writing: 95%+ original. The tool highlights which matches are concerning vs. common phrases that naturally overlap.
Can the plagiarism checker detect paraphrased content?
The tool detects close paraphrasing (similar sentence structure with synonym substitution). Deep paraphrasing (completely restructured sentences) is harder to detect. It compares semantic similarity, not just exact word matches, for more thorough detection.
How much text can I check for plagiarism?
Up to 10,000 words per check. For longer documents, check in sections. The tool processes text against billions of web pages and academic sources. Results typically appear within 30-60 seconds depending on text length.
Does the plagiarism checker store my text?
No. Your text is processed for comparison only and is not stored, indexed, or added to any database. It will not appear as a match in future checks by other users. Your content remains private and confidential throughout the checking process.
