Save yourself from accidental plagiarism

Running your document through a plagiarism scanner will reassure you that your work does not contain plagiarism - this usually means making sure that other authors' notes are not mixed in with your own, and that you have not forgotten to include any citations for direct quotations. Viper is perfect both for checking your document's plagiarism percentage, and to help you reduce and remove accidental plagiarism - before it's too late! Get informed about your document before submission and don't risk losing marks on a perfectly good essay just because of a missing reference.

Incredible Speed and Great Support

Viper isn't just a free alternative plagiarism scanner - it's also faster than Turnitin, Writecheck, and pretty much any other plagiarism checker available. Scans are blazingly fast, so you will be reading your report in seconds! You are also provided with dedicated support, meaning we're on hand to answer any queries you might have about the app.
