Fixu - Japanese Keyboard

Fixu is the Japanese keyboard that checks your grammar and tone before you send, and helps you learn from every message, so your Japanese actually gets better.

Texting friends, messaging a language partner, emailing coworkers: Fixu gives you feedback right inside your keyboard. No switching apps. No copy-pasting into a translator. Just you, writing Japanese on your own.

HOW IT WORKS
Set Fixu as your keyboard and write in Japanese like normal. Fixu checks your grammar and tone as you type, or on demand with one tap. Every correction comes with an explanation of what was wrong and why, so you stop making the same mistake. Accept a fix with one tap.

LEARN FROM THE TEXTS YOU RECEIVE
Got a reply you can't fully read? Copy it and tap "Study copied text." Fixu breaks the sentence into words with furigana, shows dictionary meanings with a tap, and translates the whole message.

SAVE AND REVIEW WITH FLASHCARDS
Save words and phrases from real conversations, then review them in the Fixu app with spaced-repetition flashcards. You learn the Japanese you actually need, from the people you actually talk to.

SEE YOUR PROGRESS
Track which grammar points trip you up most, how often you write error-free, and which areas are improving week by week. Get a weekly recap of how much Japanese you wrote.
