I have been manually spinning my tier 1 articles using spinchimp free version. Only problem is though, IT TAKES AGES to spin each article (rewrite each sentence 3 times then spin each word where possible). Doing this usually takes me around 2/3 hours. With this in mind, im thinking of buying spinchimp pro to auto spin the article and then correct any errors. Now my question, should I go with spinchimp pro? the thing that attracts me to it is the 'part of speech engine' AI. Do other spinners such as SC and TBS have better AI?
