So, back in Korea where I live, there’s this one 'holy grail' textbook everyone uses to prepare for the JLPT. But once I finished the whole thing, there was literally nothing else left to study, so I just ended up reviewing that same book over and over. I desperately needed new practice material. So... I just built something for myself.
The tool is called DANGO AI (https://dango.kr) — the idea was simple: AI generates unlimited JLPT-style reading and listening passages at whatever level you set. You pick N1/N2/N3, choose a difficulty, and it spits out a fresh passage with comprehension questions every time. No repeats, no memorizing the answer key.
I used it pretty much exclusively for the last few months leading up to my N2 exam. Passed. Honestly wasn't sure it would work until it did.
The feature I ended up using the most was kind of an accident — while reading a passage, you can drag any text and it automatically saves the word or phrase to a personal vocab note, with the meaning and a natural example sentence. I'd do a session, then flip through my notes at the end. Felt like actually building my vocabulary instead of memorizing a shared list.
Some things it does:
Generates reading passages + questions at N1/N2/N3 (customizable length, topic, difficulty)
Listening practice with audio generated from the scripts
Drag-to-save vocab while reading → personal note with meaning + example sentence
Review mode where you can quiz yourself on your saved words
It's not perfect and I'm still working on it, but if you're grinding for JLPT and want more reading material than you'll ever run out of, it might be worth a look: https://dango.kr
