Zistica Mojiiq

Write Japanese anywhere — MOJIIQ checks your grammar as you type.

HOW IT WORKS

Type Japanese in any text field on any website. Mistakes get a red underline instantly. Click the underline to see what's wrong, why it's wrong, and fix it with one click. That's it.

WHAT IT CATCHES

• Particle errors — を vs に vs が vs と (the #1 mistake for learners)
• Verb conjugation — wrong te-form, stem errors, ichidan/godan mix-ups
• Adjective errors — い-adjective + だ, な-adjective + の
• Spelling — こんにちわ → こんにちは, katakana typos
• 837 grammar rules run instantly, with deeper AI analysis after you pause

JLPT LEVELS

Set your level from N5 to N1. Corrections are tagged by difficulty so you see what matters at your stage. The extension tracks which patterns you use correctly over time — no quizzes, just real writing.

EXTRA TOOLS

• Autocomplete — suggests natural Japanese as you type
• Hover dictionary — hold Alt/Option over any word for reading + meaning
• Video furigana — adds readings above kanji in YouTube/Netflix subtitles
• Vocab saving — save words for spaced repetition review (30 free, unlimited on Pro)
