textlint vs Trinka

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.
