ProWritingAid vs Revise

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.

Revise is a browser-based AI document editor and word processor, offered through web, API, and self-hosted options. Its AI agent can brainstorm, draft, edit, rewrite, and search the web for citations, presenting proposed changes for review. AI edits appear as tracked changes that users can accept or reject individually. The editor supports DOCX, PDF, Markdown, and text files, with export to DOCX, PDF, and Markdown. Revise supports models from OpenAI, Anthropic, Google, and xAI, plus real-time collaboration and focused document comment threads. ChatGPT and Claude plugins use the customer’s subscriptions, while an SDK connects external agents through MCP. Documents and AI conversations are described as private by default, encrypted in transit and at rest, and deletable by the user. The Free plan costs $0 per month and includes a daily AI limit. Plus costs $8 per month, Pro $20 per month, and Max $80 per month. The API is billed per request, with 18 MiB uploads and PDFs up to 100 pages.
