Japanese grammar can be very particular, especially when dealing with particles and the more polite forms, like in emails. To this day, I am still making mistakes without anyone ever correcting me!! I got frustrated so back then, before ChatGPT and all the fancy custom GPTs were a thing, I thought it would be a cool idea to hook up GPT3 (yes GPT3, not even ChatGPT) to an UI and ended up building this little tool for myself, calling it fittingly, “FixMyJapanese.”
It’s gotten better over time, and now it’s a free service that anyone can use at https://fixmyjapanese.com. Check it out!
What exactly is this?
Fix My Japanese is an AI-powered service that helps you figure out where you’re going wrong with your Japanese and learn from your mistakes. (yeah, yeah, I know, everything is AI-powered these days, but to my defense, this existed before the AI craze started)
Basically, you give it some Japanese text, and it:
- Gives you back a corrected version of what you wrote.
- Tells you exactly what the grammar mistakes are and explains why they’re wrong.
The idea is that by seeing these corrections and explanations, you’ll start to recognize the patterns and make those mistakes less and less.
It even has different politeness levels you can play with:

The “Kansai” option isn’t really a politeness thing, but as a Tokyoite, I find it hilarious to see how 日本語を話せません。ごめんなさい
turns into 日本語話せへん。すまんな。
. It’s a great party trick if you’re hanging out with friends from Osaka. 😉
Different Senseis, different styles
There are also different “Senseis” to choose from, each with their own style:

Each Sensei will give you slightly different corrections and explanations. For example, let’s say you wrote:
申し訳ございませんが、僕はこのリンゴを聴こえません
Yuki might say:
申し訳ございませんが、僕はこのリンゴを見ることができません。
While Sakura might say:
申し訳ございませんが、私はこのリンゴを食べられません
The Senseis change and get better over time, so try them all out and see which one you like best!
Tell me what you think!
