I need a way to spellcheck/grammar check Japanese text in Web. Are there any existing browser solutions (plugins) or API, that could help achieve that?
I've investigated this topic and existing solutions do not satisfy our needs because they work quite strange. Solution, that I checked was https://languagetool.org/, which claims to check the spelling and grammar on Japanese text, however, it always says that the text is valid, even if it is not. Also I checked https://www.stars21.com/spelling/japanese/ which is using Yahoo Star - it works fine but has no API or browser plugin.
Any ideas would be appreciated.
