FAQ

Is paraphrase Grammarly better than QuillBot?

Both these tools have a paraphrase feature. However, Quillbot provides more sophisticated results in rewriting ideas and thoughts. Grammarly, on the other hand, shows good results in checking spelling and grammar for errors and mistakes. Please, remember to try each of these services on your own before making a judgment.

What is the disadvantage of QuillBot?

There are a few cons when using Quillbot. The first disadvantage is that users cannot try the plagiarism feature for free. But the good news is that the paid subscription to the service is rather affordable, it costs only $9.95 per month. Another con might be the fact that you can scan only 20 pages per session with a paid subscription.

Is QuillBot not free anymore?

Quillbot offers certain basic features for free use. In case you need to paraphrase some sentences, or check your text for grammar mistakes then users are able to do so free of charge. However, if you are in need of plagiarism detection, or you need some advanced aid, get ready to sign up for a paid subscription.
