That is why we’ve created a catalog of the free Copyscape alternatives. These tools work exactly like Copyscape, and many of them have extra features as well. They’re also budget-friendly and hence, more accessible than Copyscape. If you’d like to know the details about such software, then keep on reading. 

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. 
  • The plagiarism checking seems to be superficial. Many users have said that Copyscape fails to do a thorough sweep of all sources. Plagiarism remains despite having passed the content through the software.
  • Another issue is that one can manipulate Copyscape. Users have said that by altering a word, plagiarised content escapes detection. This means that one can get away with using plagiarised content by simply changing a word or two. 

For such reasons, digital writers and publishers are on the lookout for effective Copyscape alternatives.
