JLPT Mock Test Tool I am Making

Hello all,

Last December I attempted my N4 but ended up failing only on the grammar section but did very well on the others. I decided that I needed to focus study on not just the grammar but also how the JLPT test questions are structured. To help with this I habe made a site called www.jlptopencatalogue.com.

I know AI makes mistakes but what I have done is gotten it to generate a bunch of test questions by level section and question type, then also built a system to have human verification and review of the questions to make sure they are actually good.

I wanted to share and if anyone finds it useful if you have any feedback it would be wonderful!

Thanks very much!

Super cool! I like the design and how well it works. Maybe questions are not consistant and do not correspond really well to the real ones (actually really, they were not bad for the most part). But even if sentences and texts are not same as those from JLPT, they test very simmilar stuff, and when I do mitake, which I do, it tels me what I did wrong, and explains the idea of the point, as well as the idea of other respones. Also, it seems to use a right type of vocab.

Some questions are broken of course, but I’m absolutly okey with it.


I personally think, in this case, Japanese person would choose B and jump from the bridge, or do harakiri (clasics).


The ones with audio and reading seem to be quite easy to guess without even listening or reading. On the other side grammar ones are very good (kanji probably too, but I haven’t done enough, saying just from the format). For now I see the most profit in grammar ones.

You are like https://jlpt.migii.net but much better in terms of ui/ux and explanations, minus is that you are AI, and it’s hated on Reddit. Again, on the bright side, Reddit is probably just 1-4% of all people who learn Japanese.

It’s basically the best AI based thing I’ve used so far! I want to use it, so I hope you continue working on it! When you have enough of those quality questions, I beleve you’ll be able make it a paid product, and people will use it.

Recomendations for now are:

  • I think Reading and Listening are the week points, because you can guess from the answers alone. Probably an extra layer of AI self check specifically for answers for those two formats should be there, so it make each answer believable if you don’t know what was the content.
  • “Skip this question” button (for cases when question is unusable)
  • Just as an idea, I think a small ux fix will help a lot. The “Practice” section looks like the entry point of the core functionality, so in my opinion it should be evidently pointed to, so new users won’t get distracted by everything, (now it’s just one of other 5 buttons, while it is actutally the single core feature). I think you could make it somewhat more prominant, so it’s evident where to start when you land on the page for the first time.

This is by far the greatest feedback i have ever gotten! I truly appreciate your detail and will absolutely work to make it better!

Yes AI is pretty hated, but i think in this context it can for sure be helpful!

Thanks so much again for the details!

Thanks so much! Happy to help!!

safari tells me the https certificate is for jlptopencatalogue.com but the website has the address www.jlptopencatalogue.com and so it is saying the website is insecure. can you add an alias for the certificate?

Somewhat minor, but you should consider using a Japanese font. The default font for Asian characters uses Chinese as a base so you end up with some kanji that are harder to read. Looks like this instead of 漢字 for example.

Super cool!

  • Going to need a more high contrast color mode though, the softness of the palette makes my eyes strain a bit sometimes. = I did see there is a theme change but this does minimal amounts, the side bar information with the slightly differing sand colors are what trips my eyes
  • As mentioned above, a font selector would make a world of difference! = Nevermind, i found there are two possible fonts in the settings after logging in.
  • The spaces between things in the Japanese text is very distracting.

this is actually great, while i have yet to build a huge streak in bp (i like wk alot, and translating song lyrics as a hobby plus a kanji app and jisho daily visitor) i find it sliiiightly difficult to finish my reviews. though i’ve been having fun with translating the questions in my head, more often I input in the barely right answers (the one that triggers a short msg nudging you)

anyway, i checked it out and the quizzes are fun. though firefox kinda warned me of proceeding with accessing it (no https and bad cert? it said)

ps. is there something special when i know i can detect a site made (i assume not exclusively) with ai lol, i kinda do have that skill. its the font i guess
