PerfectIt vs Revise

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.

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.
