The AI texts you could generate for learning words you repeated today used to have at least some reasonable grammar and complexity to them.
Now it's all just "The man has a cat. The cat is furry. The man is in the kitchen. The cat looks at the man."
Honestly, this is barely A1 level of language learning and useless to everyone above A1-2 level in a language. It also doesn't help with memorization because the sentences are so awkwardly simple.
At the very least, the old method for generating text should be brought back that was capable of writing actual sentences and (mostly) coherent paragraph stories.
Optimally, the user should be able to select the desired level of complexity - maybe a simple "beginner" level with the current version and an "intermediate" and "advanced" one that provide better training.
