Fix My Japanese

Fix My Japanese checks the Japanese you wrote and tells you what to change, and why. Paste or type anything (a sentence, a Slack message, a whole email), tap Fix It, and you get the corrected text back with every change listed separately: what you wrote, what it should be, and a short note on the rule behind it. Each correction stands on its own, so you can take the ones you agree with and think about the rest. What it catches - Particles: は against が, に against で. The mistakes that are hardest to spot in your own writing. - Conjugation and tense: て-form, conditionals, and transitive/intransitive pairs like 開ける and 開く. - Politeness: choose Formal (〜ます) or Polite (〜いたします) and it holds the whole text to that register. The email that starts polite and slips halfway through gets flagged. - Kanji and okurigana: IME conversion slips (帰る for 返る) and okurigana that wobbles (行う, 行なう). - Phrasing that is grammatically correct but that nobody actually writes, rewritten to what a native would say. Made for - Proofreading a work email before you send it - Checking homework before class - JLPT writing practice - Anyone who has stared at a sentence wondering whether it sounds rude Your corrections sync between iPhone and iPad over iCloud, so History looks the same on both. Three corrections a day are free. A subscription removes the limit. The app interface and the explanations are in English. The corrections themselves are Japanese. The AI is accurate but not infallible. Treat it as a well-read second reader, not an oracle. - Privacy Policy: https://fixmyjapanese.com/privacy - Terms of Use: https://fixmyjapanese.com/terms
