Analyze My Writing vs ProWritingAid

Analyze My Writing is a free web-based analyzer for text content and readability. It counts words, sentences, characters, punctuation, and word or sentence lengths. The service lists common words, two-word and three-word phrases, and a word cloud. Readability results include Gunning Fog, Flesch-Kincaid, SMOG, Coleman-Liau, and Automated Readability indices, plus Fry and Raygor graphs. It calculates lexical density, shows parts of speech and tagged sentences, and highlights words that can indicate passive voice. Cloze tests can remove every nth word, selected words, or a random percentage; selected-word mode requires fewer than 5,000 characters. The Free plan costs nothing, needs no registration, and allows unlimited texts, with length limited by the browser and system. Submitted text is not saved, and no cookies or third-party cookie code are used. Log files may include technical visit details. Users must be at least 18.

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.
