Script installation: WaniKani Katakana For On'yomi

Acknowledgements This is a continuation of [Userscript] WaniKani Katakana Madness by @Miaka who is no longer active. The vast majority of the code was written by Miaka.

Known Issues:
Script compatibility mode is required.
Replacement into katakana does not work perfectly during reviews/quiz. If you show full information it should work.
During lesson quizes, the input will not accept single n as a valid input. Ex: To get セン you must type senn. Consider this practice for japanese keyboard input on less lenient software :slight_smile:


Everything? As in kanji and vocab? Or just for kanji?

Just Kanji. Will clarify op.

Question. Will typing the answer in hiragana be counted as wrong?

Your answer will automatically be converted into katakana when appropriate.


It’d be nice to have an option to switch everything over to katakana. I presume it’s trivial to do in the code, so I’m going to try and tweak it for myself.

Thanks for the update!

Depends on what you mean by everything. Making the current replacements work for all items should be pretty trivial (delete some if statements), replacing additional content is more annoying.

Hey, thanks for taking over this script.

I wonder if you would be able to add functionality for extra study questions as well?

It doesn’t break anything, it’s just a bit jarring doing extra practice and using hiragana instead.

I can look into it.

There is a new version now that should support extra study. I don’t really use that feature of wk, so please let me know if there are any issues.

Seems to be working perfectly in Recently learned extra study, I don’t plan on making a kanji mistake just to test that out though, so I’ll let you know if I ever do.

Thank you so much!

Hi Guys,

It seems I cant write ン during lessons. It always enters N and readings cant get validate.
Is this a specific known issue of Katana for onyomi ? or I do I have to much userscripts etc ?

Try typing nn, it should turn into ン. It’s a known issue that I haven’t managed to fix.
