Welcome! Head straight to our filters. Select "Core Skills (Individual Contributor)" under the primary filter. This curates essential starter models like the "5W1H Framework" and "PDCA Cycle" to quickly help you get the hang of structured thinking.
What's the difference between the two filters?
Think of it like this: The primary filter (Role) suggests a toolkit for your specific job (e.g., Manager, Executive). The secondary filter (Skill) helps you sharpen a specific tool, like Communication or Strategic Thinking, regardless of your role. We recommend filtering by role first, then by skill.
Did you create these models yourselves?
Not at all. These mental models are classics. They're proven frameworks from psychology, physics, business strategy (like concepts popularized by Charlie Munger), and renowned consulting firms. Our job is to curate, simplify, and visualize them for you.
Can I find more in-depth resources here?
Our focus is on giving you a clear, actionable overview of each model. In the future, we plan to add "Further Reading" sections with book and article recommendations for those who want to dive deeper.
How does payment work?
Browsing our core library is completely free. Upgrade to a Premium account for a single, one-time payment to get permanent access to all advanced features—like our downloadable model library, exclusive deep-dives, and eBooks.
Is the site mobile-friendly?
Absolutely. Our site is fully responsive, so you can access your mental model toolkit and learn on the go from any device—phone, tablet, or desktop.
