Emacs-langtool VS languagetool.el

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.

https://github.com/emacs-languagetool

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.

I use https://github.com/mhayashi1120/Emacs-langtool

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.

This can be done most comfortably with org-mode in emacs. It offers a lot of features, and they all operate on plain text. There are also nice integrations for git and languagetool, but I guess those are less exclusive.

So far it pretty great and easy to install. Plus is does grammar checking as well. I used this package in Emacs but there a several to try.

For grammar checking you can try https://github.com/PillFall/languagetool.el

I've tried this package but for some reason, it doesn't work, it just exits with an error code, whatever the language.
