The problem with immersion
Podcasts, books, and shows expose you to real language — but you can't control what words appear. You can spend an hour listening and never encounter the word you studied yesterday.
The problem with flashcards
Drilling a word in isolation is not enough to make it useful. Without native content to anchor your understanding, most of what you review won't survive contact with the real language.
The Jengo approach
Jengo builds paragraphs around the words you actually need to study. Listen back to each paragraph to compound your gains. This is no-compromise learning.
Jengo uses custom spaced repetition to schedule every word at the moment you're most likely to forget it.

I lived in Japan for two years, read grammar dictionaries cover to cover, worked through dozens of books and hundreds of podcasts, spent three hours a day on flashcards and four hours speaking with natives, and “learned” more than 15,000 words. I did everything right.
But there was always a functional gap between my flashcards and the real language that cost me thousands of hours to close. Jengo is the tool I always wanted, but never had.
