I use https://languagetool.org/ for that. I have integrated this Java program in Vim as well. Every time I think I finished a piece of write, I run the ":LanguageToolCheck" command to learn that my writing still leaves a lot to be desired.

Is the Java tool directly connecting to the site for the checks or it uses some kind of local database? Is it updatable?

I use it as a local Java program and you can enable / disable all kinds of rules. You can also write your own.
