Hey Product Hunt!
I'm Amit, the maker of MOJIIQ.
I built this because I kept making the same Japanese grammar mistakes — wrong particles, broken verb conjugation — and every tool I tried just underlined the error without explaining why. That's useless for actually learning.
MOJIIQ fixes that. Every correction shows:
→ What's wrong
→ The grammar rule behind it
→ A native phrasing alternative (Pro+)
It works as a Chrome extension inside Gmail, Slack, Notion, Discord, GitHub — anywhere you type Japanese. No copy-pasting into a separate tool.
Free tier is generous. No account needed to try it right now: https://mojiiq.zistica.com/check
Would love to hear from anyone learning Japanese — what's the grammar point that trips you up most? I'll reply to everyone.
