implement "languagetool" on my website

I want to use “languagetool” on my website. Let’s there is a text area where the user can write some text. If they make any grammatical mistake then words will be highlighted and suggest the probable solution.

Please suggest! so that I can implement “languagetool” on my website.

This documentation should still work: Integration On Websites - LanguageTool Wiki

Thanks for the reply. Yes, it’s working. I have some questions -

1.Is “languagetool” supports Korean text?

2.Is this possible to implement “languagetool” without - tinyMCE ?
I mean a normal textarea, where the user can write some text. If they make any grammatical mistake then words will be highlighted and suggest the probable solution.

LT doesn’t support Korean, sorry. For widgets other than tinyMCE, you’d need to develop your own integration with the API or use our Premium version. For the Premium offering, please contact us via email (see LanguageTool - Imprint).
