ConceptFlow: Mental Models

AI gives you answers fast. What matters is whether you can still judge, transfer and apply what you know. ConceptFlow helps you build your own thinking toolkit — one concept at a time. ONE CONCEPT A DAY Every day you get a featured mental model, from opportunity cost and confirmation bias to second-order thinking. Short, focused, and doable in a few minutes. READ IT, SEE IT, USE IT • Concept page: a plain-language explanation that reads top to bottom • How it works: animated mechanisms that show the model in motion • In real life: psychology-based applications and everyday decisions • Further reading: curated books and resources DAILY PRACTICE, ONE IDEA PER SCREEN Guess first, then see the mechanism, put the steps in order, tell look-alike ideas apart, and explain it in your own words. Active recall instead of passive reading. CONNECT IDEAS INTO A SYSTEM Explore an interactive concept network. Expand any node to discover related ideas and the paths between concepts, so knowledge stops being fragmented. NOTES AND AN AI TUTOR Capture thoughts and images as notes. Ask the AI tutor about whatever is on screen, by text or live voice. PRIVATE BY DESIGN No account required. No ads, no tracking. Your concept networks, notes and progress stay on your device. Who it's for: heavy AI users who want to keep thinking for themselves, lifelong learners, fans of Charlie Munger's latticework of mental models, product managers, founders, and anyone who makes decisions. AI-generated content may contain mistakes and is for learning only — it is not professional advice.
