DeepL Write vs textlint

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.

textlint is a free, open-source tool for checking natural-language text against rules users install and configure. It parses text into an abstract syntax tree, evaluates that structure, and reports errors or warnings. Markdown and plain text are supported by default, while plugins can add HTML and other formats. The tool has no bundled default rules, so users need to select and set up the checks they want. Its CLI can automatically fix problems and produce output in multiple formats. The project lists integrations for Visual Studio Code, Vim, Emacs, Atom, Sublime Text, micro, and NetBeans, and text checks can run in GitHub Actions workflows for commits and pull requests. The CLI can also run as an MCP server, allowing AI assistants to lint and fix text using a project’s textlint configuration. For browser use, @textlint/editor is described as an offline text-linting extension. Developers can use the package’s high-level APIs to integrate textlint into applications. It requires Node.js 20 or later and is MIT-licensed.
