Plagiarism Checker
About this plagiarism checker
This free plagiarism checker searches the live web for a handful of representative sentences from your text and reports which ones already exist on real, indexed pages — useful for double-checking a draft before you publish it, or verifying that a piece of writing is original.
Paste your text, tap "Check for Plagiarism," and within a few seconds you'll get an originality score plus links to any matching sources found. Nothing you type is stored — your text is only sent when you tap the button, purely to run the check. If you tap "Share," we'll save what you typed and the result so your link keeps working whenever someone opens it.

Frequently asked questions
Is this plagiarism checker free? ↓
Yes, it's completely free to use with no signup required.
How does it check for plagiarism? ↓
It picks a few representative sentences from your text and searches the live web for each one as an exact phrase. Any sentence that matches a real, indexed page is flagged with a link to that source. It checks a sample of the text rather than every sentence, so treat the score as a strong signal, not an exhaustive scan.
Is there a length limit? ↓
Yes, up to 3,000 characters per request, enough for a paragraph or two at a time.
Does this tool store my text? ↓
Your text is only sent to our server when you tap "Check for Plagiarism," purely to run the check. It isn't saved afterward — unless you tap "Share," which saves what you typed and the result so your link keeps working whenever someone opens it.
