Using Someone Else's Words Without Saying So
Plagiarism means copying text, ideas, or work from another source and passing it off as your own, whether it's a sentence, a paragraph, or a full article. It can happen by accident too, like forgetting to rephrase something you read while researching.
Compare Your Text Against Sources You Choose
Paste your content and reference material, or let the tool search the web for likely matches. It checks for overlapping phrases and shows you exactly where they are, no external database required.
Local similarity scan
Compare your text against reference text you provide. Nothing leaves your browser unless you choose to search the web.
Find sources automatically
Turn on web search and the tool looks for likely source pages on its own, so you don't have to track down references yourself.
See exact overlaps
Matching phrases are highlighted, so you know precisely what needs rewriting.
One Copied Line Can Cost You More Than You Think
Search engines can penalize duplicate content, and readers lose trust in work that isn't original. A plagiarism checker helps you catch these gaps before you publish, not after.
Protect your rankings
Search engines favor original content. Duplicate or copied text can hurt your visibility, even if it was unintentional.
Build trust
Original content shows readers, clients, and platforms that your work is genuinely yours.
Catch it early
Fixing an overlap before publishing takes minutes. Fixing it after can mean lost rankings or a damaged reputation.
Three Ways to Catch It Before You Publish
Compare against a source you already have
If you know where the overlap might be coming from, paste that text in directly and get an instant comparison.
Let the tool search for you
Don't have a source in mind? Turn on web search and the tool looks for likely matches on its own.
Review what's highlighted, not just the score
A percentage alone doesn't tell the full story. Check the highlighted phrases to see if they're a real problem or just common wording.
Anyone Who Publishes Content Can Use It
Bloggers and content writers checking a post before it goes live
Students checking an assignment before submission
Freelancers and agencies making sure client work is original
Anyone reusing or rewriting research, notes, or reference material
The Score is a Starting Point, Not the Final Word
A similarity score just tells you how much overlap exists. What matters is what's actually highlighted.
Highlighted phrase matches a common expression?
Leave it, this isn't real plagiarism.
Highlighted phrase closely matches a specific source?
Rewrite it in your own words, or add a citation.
Multiple long highlighted sections from the same source?
Rework that part more thoroughly, a small edit won't be enough.
