LTEX provides offline grammar checking of various markup languages in Vim/Neovim using LanguageTool (LT) and coc.nvim. LTEX currently supports BibTEX, ConTEXt, LATEX, Markdown, Org, reStructuredText, R Sweave, and XHTML documents. In addition, LTEX can check comments in many popular programming languages (optional, opt-in).

The difference to regular spell checkers is that LTEX not only detects spelling errors, but also many grammar and stylistic errors such as:

  • This is an mistake.
  • The bananas is tasty.
  • We look forward to welcome you.
  • Are human beings any different than animals?

A classic use case of LTEX is checking scientific LATEX papers, but why not check your next blog post, book chapter, or long e-mail before you send it to someone else?

Find more information and documentation about LTEX on the official website.

LTEX is a successor (since it's a fork) of the abandoned LanguageTool for Visual Studio Code extension by Adam Voss†.
