Fix My Japanese

What it does

The most comprehensive AI tool for Japanese learners and pros. Real-time grammar correction with detailed explanations, dialect support (Kansai-ben!), and native apps for iOS and macOS. Don't just fix it—master it.

Check Japanese grammar, particles and keigo for free. Fix My Japanese corrects your text with AI and explains every change, so you learn from the fix.

Fix your Japanese instantly. AI-powered corrections with explanations for grammar, tone, and natural phrasing. Paste your Japanese above and hit Fix It! , and your corrections and explanations will appear side by side. Most grammar checkers were built for English and treat Japanese as an afterthought, which is why they catch a missing 。 and miss everything that actually makes writing read as foreign. Fix My Japanese checks the things that go wrong in Japanese specifically: A corrected sentence on its own teaches you nothing. You will make the same mistake next week. Each change is listed separately with the original text, the replacement, and a short explanation of the rule or the usage…from fixmyjapanese.com

  A Japanese learning app focused on efficient vocab/grammar acquisition2022 · lessons.nihongo-app.com · ▲161

  Hey HN, it’s been 8 years since I posted on here about the launch of my Japanese dictionary app Nihongo [0] and I’m finally back with a new app: Nihongo Lessons! Think of Nihongo Lessons as the textbook to Nihongo’s dictionary. It’s an app for learning Japanese, specifically made for learners who are serious about becoming fluent, and want a guided set of content that will help them efficiently acquire vocabulary and grammar. The project came about when Adam Shapiro of Japanese Level Up (Jalup) [1] announced last April that he was shutting Jalup down. As a fan of Adam’s work I was bummed to…

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
