Hi Edynas, I have two thesaurus programs I use when writing...Mobysaurus and WordWeb. They both have free versions and are a great help when you can't think of the right word, or an alternative word. The problem with synonyms is knowing which ones have almost exactly the same meaning and even then you'll have to make adjustments to the surrounding words. These are things no rewriting software can do and why they don't really work to create a well written article. Please feel free to PM me and I'd be glad to send you my email address and help you when you get stuck.
