PerfectIt vs ProWritingAid

PerfectIt checks professional documents for consistency mistakes and style issues, including hyphenation, list punctuation, acronym definitions, spelling, capitalization, numbers in sentences, headings, comments, extra spaces, and placeholder text. Its built-in styles cover UK, US, Canadian, and Australian spelling, as well as styles for organizations including the European Union, United Nations, World Health Organization, Government Publishing Office, Australian Government, and American Legal writing. Users can create custom style guides and manage terminology and brand voice rules. PerfectIt works inside Microsoft Word and PowerPoint, though PowerPoint access is limited to Elite, Team, or Enterprise subscriptions. Chicago Manual of Style checking requires a CMOS Online subscription. The Windows edition does not connect to the internet or a local network, keeping documents on the computer. PerfectIt Cloud sends documents securely for checking and deletes them afterward; the site says no one else can access them during checking. It does not generate or rewrite text, leaving editorial decisions to the user. Plans are billed per month, and a free 14-day trial is available without credit card information. PerfectIt is based in London and was founded in 2009.

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.
