I built a free Japanese grammar checker that explains why you're wrong, not just what's wrong.
Hey IH — I'm Amit, building MOJIIQ.
The problem: every Japanese learner tool I tried flagged errors but never explained the underlying grammar rule. You'd fix the mistake, make it again tomorrow, and never actually learn.
So I built MOJIIQ — a Chrome extension that checks your Japanese in real time on Gmail, Slack, Notion, Discord, and any site you use. It doesn't just correct you, it shows:
The grammar rule you broke
Why the correction works
A native phrasing alternative (for advanced learners)
It's calibrated to JLPT levels N5–N1 so the feedback matches where you actually are.
Free tier is generous — no account needed to start.
Would love feedback from anyone learning Japanese or building in EdTech/language learning.
