very cool, thanks

When I was learning the Japanese kana (hiragana and katakana), I downloaded seven or eight different apps from the App Store, and finally chose one called MARU. It's a product by an independent developer, and it's very simple and efficient. Even for a mature topic like kana, different apps have different perspectives and approaches to solving the problem. I think this is still something that AI can't replace: good product taste and aesthetics, and solutions to problems in a specific field. However, I think another problem might arise: if a product is very good, someone might easily use AI to create a similar product with a different interface and sell it at a lower price, leading to intense competition. How should developers deal with this?

There's already one available at https://sqlitestudio.pl/, which I've been using for many years, and it's very stable.

Even for Chinese people, Journey to the West is a somewhat difficult text because it belongs to classical literature. Using some children's books published in recent years, and progressing gradually, might be a better approach?
