Anyone actually using a local LLM as their daily knowledge base? Not for coding, for life stuff. What's your setup?

So I've been going down a rabbit hole lately and I can't find many people actually talking about this specific use case. everyone here runs local LLMs for coding, chat, maybe some creative writing. cool. But what about using it as a proper personal knowledge base? like, dump your own notes, PDFs, random docs into it and actually query your own life privately, every day. I tried looking into this seriously and hit a wall. Most resources either assume you're a developer building something, or they're 2 years old and recommend tools that have completely changed since.
