On August 4th, my son suffered a severe brain hemorrhage from a rare and undiagnosed brain condition, thrusting me onto the steep learning curves of the medical system, neurosurgery, rehabilitation and other topics. So I build a RAG + LLM system using Claude 100k to help me quickly learn and understand — that works by ingesting his medical records, my log of detailed note (in OSX notes app) and full index and summaries of relevant research papers.
