Hey Cathy, thanks for sharing about WordAi. It certainly is interesting, to say the least. I guess at some point all of us would want to automate our business and will look into programs like these for a solution. The example you showed gave me a very clear indication that the algorithm isn’t quite there yet. You seem too lenient in grading it because to me, it is practically unreadable. I believe hiring writers is a better use of that money.
The instant article spinner or paraphrasing tool carefully scans the article you enter, looking for all the words that it can replace with synonyms. All the words or phrases that will be replaced are colorfully highlighted to make them prominent and easy to identify. By clicking on each of the highlighted text, you can see the original word along with other suggestions, and you also have an option to add your own word. To restore the original text, just click the original word.
Don't you hate it when your synonyms make no {sense|perception}? Don't settle for the "content garbage" that most spinners vomit out. WordAi can tell subtle differences between words and makes sure each synonym it picks makes complete sense. This gives you articles that are automatically readable, without you needing to spend countless hours fixing them up!
That’s really weird. I have tested WordAI and Spin Rewriter with Copyscape and the results were always 80%+ uniquness, even 90%+. I don’t know how u spun the content to achieve such low results, but this is definitely way too bad. As for the block spinning, I have to be honest, this is the first time I’m hearing of it and I will have to check it out when I have a bit of time, but generally, yes, in the best case scenario, you would manually touch your Tier 1 content to make it 100% human readable and as unique as possible. For lower tiers, you can do pretty much anything, but again, the better quality of content, the better results you will have. That’s in my opinion and experience.

X-Spinner has super-advanced functions such as auto-grammar fix, for example it will correct "a apple" to "an apple," plus it can spin "I want to eat the apple, orange and banana" to "I want to eat the banana, orange and apple." We can't list all functions here, there are too many to list! - But one thing is sure, X-Spinner will give you the best rewritten article - no other spinner can do what X-Spinner does!
