When you integrate Perfect Tense with Spin Rewriter, Perfect Tense will check your seed article for grammatical mistakes before Spin Rewriter spins it. With higher quality seed articles, Spin Rewriter will be able to create higher quality content. In many instances, these improvements will lead to spun content that is higher quality than the original.
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.
