How This Plagiarism Checker Works
This tool gives you two practical, completely free ways to check for duplicate or copied content — both run instantly in your browser with no word limit.
Paste Your Text
Add any amount of content — articles, essays, or assignments.
Analyze
The tool splits it into searchable phrases automatically.
Verify Online
Click Google or Bing to check each phrase against the web.
Or Compare Directly
Paste two texts to instantly see their overlap percentage.
Two Modes, Two Real Use Cases
Search-Assisted Check
Best for checking your own article or content against the wider internet. Since no free tool can privately scan the entire web automatically, this mode gives you fast, one-click Google/Bing searches for each phrase so you can confirm originality yourself.
Compare Two Texts
Best for comparing a student’s submission against a source document, or checking two drafts against each other. This works fully automatically and shows a real overlap percentage with matching phrases highlighted.
Frequently Asked Questions
Does this tool automatically scan the entire internet?
No. A private index of the whole internet is only available through paid services like Copyscape or Turnitin, which require expensive backend infrastructure. Instead, this tool gives you one-click Google/Bing searches for each phrase so you can verify it yourself, plus an automatic comparison between two texts you provide.
Is there a word limit?
No, you can paste text of any length in both modes.
Is my text stored anywhere?
No, everything happens directly in your browser. Nothing is uploaded or saved on any server.
How is the overlap percentage calculated in Compare mode?
It uses 5-word phrase matching (shingling) between the two texts — a standard technique used by many plagiarism detection systems — and highlights every matching phrase.
Is this free and unlimited?
Yes, both modes are completely free with no sign-up and no limits.
