How to Build a Second Brain in 2026

The volume of information a professional encounters in a week now exceeds what a careful reader from the 1990s would have processed in a year. The problem is no longer access. It is recall.

A "second brain" is a deliberate external memory system. Notes, captures, summaries, and source material organized so that the right context is one query away when you need it. The CODE method — Capture, Organize, Distill, Express — gives you a repeatable workflow for managing that external memory.

In 2026, the second brain has a new ingredient: a tightly-scoped AI that knows your captured content. It is not ChatGPT writing at you from a blank page. It is your own notes, your own decisions, your own context — queried through a model that respects the boundaries of what you actually know.

This course will teach you the method, the tooling, and the discipline to make it real.
