Why do people need Copyscape alternatives?

Copyscape is a trusted plagiarism detection software, which has been around for years. It’s fast and it can detect forged content within minutes, if not seconds. Thus, over the time of its existence, it has racked up a large user base. But its popularity doesn’t mean that it is without faults. 

Users have many complaints about Copyscape, the primary ones being –

  • It’s pricey. Copyscape is one of the most expensive plagiarism software in the market. Because of that, several people are unable to use it as it is beyond their budget.
