Have you ever wondered which JLPT level a given vocab or kanji belongs to while learning or reviewing it? This script will give you an indicator in the upper left corner of the screen. Here are some examples of what it looks like:
(it gives you just the lower box, not the upper one with “common” in it - that’s provided by the “WaniKani Common Vocab Indicator” script. I kept that script running for the screenshots so that you can see the two scripts are visually compatible.)
The code for this script is based on @dtwigs “WaniKani Common Vocab Indicator” script. (Thank you )
The JLPT information is taken from Jonathan Waller‘s JLPT Resources page http://www.tanos.co.uk/jlpt/.
You can install it via GreasyFork.
Before you ask, yes, the JLPT level information is visible on Jisho, but unfortunately it is not exposed via their API (there is a three-year-old thread that asks for this, but so far nothing happened). So I decided to build my own backend that serves this information.
