Submissions will never be added to our content database. Therefore, no other plagiarism checker will see your text.
This plagiarism checker is not for you if you:
Ace your personal statement for your university application.
Compare your UCAS personal statement against billions of webpages, including other essays.
Submit your assignments with confidence.
Detect plagiarism using software similar to what most universities and publishers use.
Take your journal submission to the next level.

You would never copy-and-paste someone else’s work, you’re great at paraphrasing, and you always keep a tidy list of your sources handy.
But what about accidental plagiarism? It’s more common than you think! Maybe you paraphrased a little too closely, or forgot that last citation or set of quotation marks.
Even if you did it by accident, plagiarism is still a serious offense. You may fail your course, or be placed on academic probation. The risks just aren’t worth it.
Scribbr is committed to protecting academic integrity. Our plagiarism checker, AI Detector, APA Reference Generator, proofreading services, and free Knowledge Base content are designed to help educate and guide students in avoiding unintentional plagiarism.
We make every effort to prevent our software from being used for fraudulent or manipulative purposes.
