A few years ago (before LLMs were as good as they are today) I wanted an LLM to do a RAG like memory on all the books I own. My dream was that every book I purchased would go into my LLM making it better but also giving me a reference back to the text to look up and help me get better.

Honestly I didn't expect LLMs to progress so fast. Now it just seems like an unnecessary solution to a problem that no longer exists.
