In their own words
ProWritingAid
ProWritingAid provides grammar and style suggestions through browser extensions and a desktop editor. It works with Word, Google Docs, Scrivener, Chrome, Firefox, and Edge, and browser extensions are available for Chrome, Firefox, and Edge. The free account handles 500 words at a time and includes two line-editing runs, ten rephrases, three Sparks, and three Creative Nudges per day. Premium and Premium Pro support documents of any length. Premium includes document sharing, real-time comments, and more than 25 writing analysis reports. Its plagiarism checker compares work against webpages, published works, and academic papers. The product supports English only, including general, British, US, Australian, and Canadian English. ProWritingAid says text entered into its editor is not kept on processing servers, is encrypted during processing, and is not used to train algorithms. The free plan is available; listed paid plans include Premium at $30 a month and Premium Pro at $36 a month, both billed monthly.
