Short description
LTeX is a grammar/spellchecker that bundles the open-source LanguageTool server, but always runs completely offline unlike many official LanguageTool extensions.
Why I think this tool should be added
Officially, LTeX supports VSCode and Vim/Neovim: Installation and Usage | LTeX - additionally there is third-party support for Emacs and Sublime.
Beyond text editors, there is a CLI method to check any text file that we could recommend using for people who do not use a supported editor.
Theoretically, the “server” version can also be used alongside any of these editors with LSP support, but I have not tested this: Tools supporting the LSP
Currently we use this in our official website development workspace for VSCode at Privacy Guides, and it runs completely offline as you would expect from a tool like this.
