History of Viper
Learn more about how Viper was developed.
Viper Plagiarism Checker is a web-based piece of software that is used to detect plagiarism in electronic documents. Designed especially for students, Viper detects plagiarism by scanning a document against millions of electronic resources such as books, journals and articles.
Since its launch in 2007, Viper has helped over 1.5 million users scan over 6 million essays, assignments, dissertations and other documents. With a simple 'drag and drop' scanning interface, easy-to understand scan results, and a free option available, Viper is the plagiarism scanner of choice for thousands of happy users every week.
2007 - Viper is born!
Initially developed in 2007, Viper was created to assist in checking for plagiarism and originality in the production of All Answers' custom-written research. The software was designed to check each document created to ensure no plagiarism was present.
2008 - Viper is launched
Following the success of Viper in-house at All Answers, the company realised that students and teachers alike might be interested in checking the originality of their own work. The decision was made to offer Viper to the public, and so the Viper Software was released. Launched as a downloadable program (for Windows only) and completely free, Viper quickly became very popular in the academic community.
