This is an amazing product for writers of all stages, from beginner to published.
Slick Write has features I haven't found anywhere else, things like its flow meter that measures sentence variance, or the colored map of sentence styles, and a comprehensive stats display to show weak points in writing. It also hasa great customizable filter function, so you can highlight only adverbs, or only weasel words, etc. It's cliche detection is great as well.
I cannot recommend this enough to any and all writers. It is truly the best out there.
