After my post on Biohacking your glucose with AI, I had another thought: what if I didn't just log food + exercise + energy levels, etc., but also tasks, thoughts, observations, or other notes? I learned that this kind of all-in-one journal is often called a bullet journal—which is an officially trademarked term for Ryder Carroll's bullet journaling methodology, often shortened to Bujo. Carroll has detailed methodologies for organizing, tagging, and managing information in a journal that's far beyond the scope for how I'm using the term. So to avoid conflating my approach with bullet journaling, I'm calling my technique here an AI stream journal. Mainly, I just wanted a single place where I could jot down the stream of information flowing through my mind and have AI sort and organize it for me.
