Show HN: AI Japanese grammar checker for Chrome (chromewebstore.google.com)

I created an AI grammar checker for Chrome/Edge. It works on Zendesk, Gmail, X, or any other pages. Something like Grammarly for Japanese. It includes generative AI, but it will only highlight areas for improvement, similar to Grammarly.

If you have some feedback or comments, please let me know. I want to improve this product and help you. It requires Google sign in, so little bit shame, sorry.
