Open Note a Personal Assistant
Building a RAG type personal assistant back in high school we would have quizzes that were open note where we could use the notes we took throughout the day to be able to do the quiz. LLMs have a memory issue so this would be a good way for the LLM to have a "Memory" by storing the data and retrieving whatever was necessary to answer a question or problem. RAG systems do this but they are as of right now difficult to setup run and manage especially for the normal person.
Update There was a person who made something similar to what i was thinking that uses obsidian to make notes as memories and then can search those notes for references later on https://github.com/basicmachines-co/basic-memory. Its a very cool tool but it mainly is just a way to interact and write your notes with your LLM rather than using it to build responses and answers to.
