Yes, you can spin the video description using wordai and correct the errors. In addition, check the spun content in copyscape or other plagiarism checkers.I'm creating a video site with hundreds of embedded from Youtube, Vimeo etc related to my niche. I'm planning on using WordAI to spin the video descriptions, which I'll manually review to correct errors. I'll also maintain a blog within the site consisting of unique hand-written articles (NOT spun with WordAI) for SEO purposes. Do you think it's okay to use WordAI in this manner (i.e. for spinning video descriptions only) on my money site?
