I Turned Charlie Munger’s 232 Mental Models into a Searchable Website

After months of work, it’s live: mungermodels.com.

It’s the most comprehensive Charlie Munger mental model knowledge base available online — 232 models, 14 disciplines, 1.52 million words of in‑depth content, 1,915 bidirectional links, and 9 scenario‑based navigation categories. For the first time, Munger’s frequently mentioned “latticework of mental models” is laid out in full.

Why I Built This

You close the last page of Poor Charlie’s Almanack, adrenaline pumping, ready to arm yourself with Munger’s “latticework of mental models” as he advised.

Then you hit a wall: Which models actually go on the lattice?

Munger constantly talked about building a library of models, but he never gave a complete list himself — dozens of concepts are scattered across his books, speeches, interviews, and letters. That’s the biggest trap of Poor Charlie’s Almanack: you understand the principles, but you have no idea where to start.

The “100 mental models list” posts online don’t solve this either. You find plenty of lists, each model described in a sentence or two. It feels great to read, but you only “know about” them, not “how to use” them. Everyone recognizes the words “inversion,” but how do you actually apply it? When should you use it? When does it backfire?

A list with a few lines per model can never give you those answers. They aren’t wrong — they’re just too thin.

What Makes This Different from a List Post

First, it’s not a paragraph — it’s a long‑form article.

Click on any model, say “Margin of Safety.” You won’t find just a one‑line definition like “buy a dollar for 50 cents.” Instead, you get a 6,000‑word article: starting with a real‑life example (why do you never worry about a bridge collapsing when driving across?), moving to the principle, a real case study (Buffett buying the Washington Post in 1973 when the market priced it at a quarter of intrinsic value), when it can fail, how to apply it to your own decisions, and finishing with a practical checklist you can use.

All 232 models follow this format. In total: 1.52 million words.

Second, it’s a tool, not just articles.

You close an article and forget it. A tool is something you come back to when you face a problem.

To make it truly useful, I reorganized all 232 models into 9 real‑world problem scenarios (Should I invest in this company? How do I motivate my team? Is this decision reversible? …), plus multi‑dimensional indexing (by discipline, by importance, by first character).

Third, models don’t stand alone — they form a web.

There are 1,915 bidirectional links connecting models — open “Margin of Safety” and you can jump directly to “Mr. Market,” “Circle of Competence,” “Second‑Order Effects.” Every model shows its forward references, back references, and related models.

That’s what “latticework” really means: not a list, but a web.

How One Person Did It

I built this with AI.

I defined the structure, the standards, the skeleton for each article, and handled review and quality control. AI took the massive material spanning 14 disciplines and wrote it into long‑form articles following a uniform specification. It’s a lever, not magic — topic selection, judgment, and quality are still human work.

Three years ago, systematically organizing all of Munger’s mental models by one person was basically impossible — it would have been a multi‑year project. Now, it’s possible.

I previously used the same approach to build a knowledge graph of Buffett’s 70 years of shareholder letters, and unexpectedly received over a hundred thousand reads. Comments kept asking if I could do Munger — this is my response.

In Closing

What Munger really wanted to teach was never just “read more books.” He wanted to teach an operating system for thinking — a latticework where knowledge connects and lights up automatically when you need it.

A website can’t do your thinking for you, but it can do one thing: take the latticework Munger left behind and lay it out in front of you — completely and clearly — for the first time.

The rest of the path, you’ll have to walk yourself.
