lsp-ltex VS Emacs-langtool

If you are using Emacs, I can highly recommend lsp-ltex

If you use emacs, I recommend to get some modern goodness by installing lsp-mode (or eglot) to interact with language servers and then install a latex language servers like texlab. This in my expericence really improved the autocompletion so I don't feel like I loose anything over using vscode, texlab or overleaf .Recently I also switched to lsp-ltex for language-tool integration. All those tools lsp servers can also be used from other editors with lsp support, so use what you prefer. I would only recommend emacs to those who want a fully customized and keyboard driven experience and are not afraid to eventually modify some lisp code. But it has its unique advantages, many editing tools and in addition to the still great auctex also cdlatex for super quick math typesetting.

Basically, I've installed lsp-mode and eglot at the same time. The reason is that eglot works over TRAMP, while lsp-mode not. Also, I use a lot lsp-ltex and it depends directly of lsp-mode

lsp-ltex. This is based on ltex-ls, which is a language server for grammar-checking LaTeX using LanguageTool. The setup is a bit tricky, and there are definitely some bugs and missing features, but when it's set up it's pretty smooth.

The ltex LSP server for emacs is also great: it uses LanguageTool, the same grammar checker behind textidode: https://github.com/emacs-languagetool/lsp-ltex

Language Tool does this, I believe, but I think it's modal rather than on-the-fly.

Perhaps something like https://github.com/mhayashi1120/Emacs-langtool which you can self host. Or if you don't mind SaaS - there's grammarly integration for emacs too.

There’s already Emacs package, but it works only with offline version.

Now that I checked, looks like there’s another package, but I didn’t t try it.

Check out textidote too. It's languagetool understanding \LaTeX syntax, and you can set it for flycheck-checker. Emacs-langtool coupled with langtool-ignore-fonts is also good for \LaTeX documents. You may want to configure them to disable a few rules to reduce false positives.

Didn't see it so far: LanguageTool integration in Emacs. It really helps me a lot, as I'm a making lot of language errors. LanguageTool requires Java (standalone app is a Jar file), could start is a bit long, but then it's really easy to use and for me feedback is better integrated in Emacs than for example in LibreOffice.
