There are many people who still prefer rewriting their articles by hand. They are used to write sentence after sentence and rephrase their content to ensure the quality of writing. Although it is the safest approach but it can take hours or days to complete a task. On the other hand, there also exist people who are either too lazy to rewrite their content or they understand the importance of time and hence, they look for an article spinner tool or paraphrasing tool.
And then there is the amount of time that it takes to create content with this software. I have had past experience with text spinners and although it might seem like a fast way to write content, it often isn’t! By the time you have chosen a piece of content (or multiple pieces of content to blend together), put it in the software and produced content with this software, you could instead have created content that Google loves.
