I'd like an LLM integrated spaced-repetition app. It would go along with this study feature quite well.

If LLMs continue to improve, we are going to be learning a lot from them, they will be our internet search and our teachers. If we want to retain some knowledge for ourselves, then we are going to need to learn and memorize things for ourselves.

Integrating spaced-repetition could make it explicit which things we want to offload to the LLM, and which things we want to internalize. For example, maybe I use Python a lot, and occasionally use Pearl, and so I explictly choose to memorize some Python APIs, but I'm happy to just ask the LLM for reminders whenever I use Pearl. So I ask the LLM to setup some spaced repetition whenever it teaches me something new about Python, etc.

The spaced repetition could be done with voice during a drive or something. The LLM would ask the questions for review, and then judge how well we did in answering, and then the LLM would depend on the spaced-repetition algorithm to keep track of when to next review.
