50+ thinking tools to sharpen every decision you make, inspired by Scott E. Page's The Model Thinker — with AI-ready prompt templates
Most people solve problems with instinct. The best operators solve them with models. I've been using mental models for 25 years across political campaigns, fundraising, and AI systems — and last month I turned 50 of them into this free interactive toolkit. Each card is a different lens for seeing the world: game theory, network effects, tipping points, power laws, rugged landscapes. Every model includes a business application and an AI-ready prompt template you can paste directly into Claude or ChatGPT.
