We track our physical performance with tools like Whoop, but we leave our cognitive bandwidth completely to guesswork. While juggling heavy machine learning coursework and dev projects, I kept hitting a wall of mental fatigue. I needed an analytics engine for my thoughts, not just a static diary with tedious manual tags. Enter Split-Brain: a smart journal that acts as a background pattern-finder for your mind. Zero friction: Just write naturally. No manual tagging required. Hidden correlations: The AI mines your text to reveal what drains your energy and what triggers your peak focus. Visual telemetry: Turns scattered reflections into a clear dashboard of your mental rhythms. I built this to stop guessing about my cognitive load and start optimizing it with real data. I’ll be hanging out in the comments all day—what’s one mental pattern or habit you’d love to finally uncover?
