Since a content spinner can’t (yet) perceive or understand language the way a human can, it has to always check with a dictionary before replacing one word or phrase with another one similar to it. Thus, this thesaurus which is basically a dictionary of words and phrases listed by correlation to one another is the absolute most important part of a content spinning software.
People, I’m pretty sure over half of the articles you read nowadays come out from a spinner such as this one, and you can’t even tell the difference… believe me I know – I publish a lot of these articles myself, using Spin Rewriter, and they are very good and believable, you wouldn’t know the difference between one of them and an article written by a human.

We also often require content for link building campaigns and PBN posts. This is a whole different story as for this purpose, we need to come up with sometimes thousands of unique articles for just one campaign. If you’re using automated link building software like RankerX of GSA SER, you know that sourcing original content for your campaigns is probably the most difficult part. 

Spin Rewriter integrates with almost any SEO software. This allows you to post high quality articles quickly and easily. The only drawback is that you only get something like 300 API requests every 24 hours. You can quickly burn through this if you’re doing multiple campaigns. The developer does not currently offer a plan for heavy API users but maybe they will in the future.
