DeepL Write vs PerfectIt

DeepL Write is a writing assistant for revising text with corrections, alternative wording, rephrasing, and selectable styles and tones. It lists 19 writing languages. Users can access it through mobile and desktop apps, browser extensions, or integrations with Microsoft Word, Google Workspace, Microsoft 365, and AI agents. Extensions are available for Chrome, Firefox, and Edge; listed apps include Windows, Mac, Android, iPhone, and iPad. The free version includes 50,000 characters per user per month and one file translation per user per month, for files up to 5 MB. The Write Pro add-on costs €6.99 a month, billed annually with VAT included, and is available as an add-on to DeepL Pro Individual or Team. Team plans include administration, analytics and reporting, and single sign-on; teams can share a file translation limit or assign the same limit to each member. DeepL cites ISO 27001 and SOC 2 Type II certified processes and infrastructure. For Pro, content is temporarily stored only as technically needed, then deleted unless otherwise specified.

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.
