LTEX provides offline grammar checking of various markup languages using LanguageTool (LT). LTEX can be used standalone as a command-line tool, as a language server using the Language Server Protocol (LSP), or directly in various editors using extensions.

LTEX currently supports BibTEX, ConTEXt, LATEX, Markdown, Org, reStructuredText, R Sweave, and XHTML documents.

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?

LTEX is a successor/fork of the abandoned LanguageTool for Visual Studio Code extension by Adam Voss.
