Yes, thou the main problem stated in the article ("memorizing the rectangles") is very real. Now, I don't think you need much magic / LLM stuff to overcome that problem:

1. Instead of the usual "1 new word, 1 card" have 2 - 3 new words on each card, and have each new word in 3 - 4 different cards (ideally with different inflection, meaning, nuance, etc) 2. Review cards fast and very few times each. Like 5 - 8 times / card (max) instead of usual 15 - 20. 3. Don't punish yourself, keep moving on even if you just half-remember. First familiarize and then internalize language patterns instead of just memorize words.

Review intentionally, totally concentrated on the task. 10 mins / day well done >>> 30 mins / day mindlessly.

Outcome: more fun, more effective learning, no memorizing rectangles.
