Article Builder + Spin Rewriter + Grammarly + GraphicStock is the only package you would need to generate human-readable and grammatically error-free English content suitable for Tier 1 projects and money sites (in selective cases). You can create human-readable content on a broad variety of topics with Article Builder. After that, you can check them for duplicate content with Grammarly plagiarism checker. Once you have performed those two steps, you can remove duplicate content by double-clicking on a word inside the Grammarly editor and replacing the duplicate words with synonyms.
Alternatively, you can insert the content in Spin Rewriter and use the best settings for generating a highly unique and human-readable spin. Once you have done that, you can correct any grammatical errors in the articles by using Grammarly Premium grammar checker which quickly and easily checks over 250 errors in the premium version. You can also find high-quality royalty free images from GraphicStock for using them in your money site content.
