Overview
ZISTICA MOJIIQ — AI Japanese Writing Coach
Write Japanese with confidence on any website. MOJIIQ watches as you type, catches mistakes before you send them, and explains why something is wrong so you actually learn — not just what changed, but the grammar rule behind it.
────────────────────────────────────────
HOW IT WORKS
When you write Japanese text on a webpage, MOJIIQ detects it and offers to analyse your writing. Open the correction panel with the floating button or press ⌘⇧Y (Mac) / Alt+Shift+J (Windows):
• Grammar errors flagged and corrected — particles, verb conjugations, tense, and sentence structure
• Politeness level checked — casual, polite, and business-formal registers
• JLPT-calibrated feedback — set your level (N5 to N1) and get explanations matched to where you are
• One-tap apply — swap the corrected text directly into the page without switching tabs
────────────────────────────────────────
NEW — ANIME SUBTITLE STRIP
Watch any Japanese video on YouTube, Crunchyroll, or Netflix with MOJIIQ's subtitle strip. Turn on captions and every word gets instant furigana readings from a built-in 190,000-word dictionary — no internet lookup, no lag.
• Furigana above every kanji — powered by a local dictionary, works offline
• Click any word to see its meaning, reading, and JLPT level
• Save words to your vocab deck with one tap — includes video context like "One Piece EP100 @ 4:32"
• Smart CC detection — the strip tells you when captions are off, unavailable, or loading
• Minimise to a small pill when you want to watch without it
Free accounts: 5 minutes per day. Pro accounts: unlimited.
────────────────────────────────────────
BUILD YOUR VOCABULARY
After applying a correction or clicking a word in the subtitle strip, save the key word to your personal vocabulary deck with one click. Saved words enter a spaced-repetition (SRS) review schedule. The extension badge shows how many words are due for review.
Free accounts: save up to 30 words, full SRS review included.
Pro accounts: unlimited vocabulary.
────────────────────────────────────────
HOVER DICTIONARY
Hold Alt (Option on Mac) and hover over any Japanese word on any webpage to see its reading, meaning, and JLPT level in a small floating tooltip — no tab-switching, no copy-pasting.
────────────────────────────────────────
TRACK YOUR PROGRESS
The popup dashboard shows your current and longest streak, total corrections applied, words saved and due for review, and a JLPT coverage map showing which grammar points you have practiced across N5 to N1.

PERMISSIONS EXPLAINED
MOJIIQ requests access to all websites so the correction panel and subtitle strip can appear wherever you write or watch Japanese. It does not read, store, or transmit anything from pages you visit passively. Text is sent to our server only when you explicitly press Analyse or click a word for its meaning — nothing is captured automatically. The furigana dictionary is bundled locally and requires no network access.
No browsing data is collected. No third-party advertising. Your correction history is stored in your account and is not shared.
