spinners won't offer it by default, but you can load your own thesaurus into them, i guess a Portuguese thesaurus is not so easily accessible as an English thesaurus, but i'd be surprised, if it wouldn't exist, don't forget that 200 million Brazilians speak Portuguese too along with a few other countries, around 250 million people speak Portuguese, big market, i don't think that all Portuguese speaking webmasters would make their content without spinningI think there is no such spinner offering Portuguese thesaurus but the solution is to convert your English article with some spinner and then translate the spun content with Google Translator but you have also edit the translated content manually because as per my experience Google translated content isn't 100% perfect. So you need to spend 2 to 3 minutes on each article and correct the grammatical mistakes.
