ModelMoment

ModelMoment is a mobile + web AI-assisted decision journal that forces you to apply one mental model at a time to real choices. You log a decision in 60 seconds, select a model (e.g., inversion, second-order effects, opportunity cost), and answer 3–5 guided prompts. The app then generates a “decision card” summarizing assumptions, risks, and what would change your mind. After a chosen time window (1 week, 1 month), it nudges you to review outcomes and score calibration. Over time, you get a personal dashboard showing which models actually improve your results, where you overestimate confidence, and which contexts trigger recurring errors. This is not therapy and won’t “fix your life”; it’s a lightweight system for people who already make frequent decisions and want measurable improvement without reading another productivity book.
