Kanji Monster
Kanji Monster is a free, browser-based drill that helps you memorize Japanese kanji through short, repeated practice sessions, with no signup and no app to install.
Learning kanji is mostly a memory problem, and memory rewards short, frequent, active practice far more than long cramming sessions. Kanji Monster is built around that idea. You get bite-sized rounds you can finish in a few minutes, review the characters you keep missing, and come back tomorrow to do it again.
It runs entirely in your browser. There is nothing to download, no account to create, and no lesson you have to buy before you can start. Open the page, pick where you want to begin, and you are practicing within seconds.
What it does
- Presents kanji in short, focused rounds so a session fits into a coffee break rather than an evening.
- Uses spaced repetition ideas, so the characters you miss come back sooner and the ones you know come back later, sending your time to what you have not learned yet.
- Tracks your progress locally in the browser so you can pick up where you left off without an account.
- Groups characters by common study sets so you can align practice with what you are already learning.
Why we built it
- Most kanji apps ask for a signup, push a subscription, or bury the actual practice under menus and streak notifications.
- Kanji Monster strips all of that away. The goal was a tool you could open and use in the time it takes other apps to load their onboarding.
How to use it
- Open kanji.omnu.dev in any modern browser on your phone or computer.
- Choose a starting set or difficulty and begin a round.
- Answer each prompt, and the characters you miss are queued to return sooner.
- Finish the round, take the quick summary, and come back tomorrow, because short daily sessions beat occasional long ones.
Who it's for
- Beginners starting their first hundred kanji who want a low-friction way to practice daily.
- Intermediate learners drilling specific sets to close gaps before they read or take a test.
- Anyone who has bounced off heavier apps and just wants to practice without the overhead.
