Welcome to Your AI Second Brain
Most of us don't have a shortage of ideas — we have a shortage of places to put them. Notes scattered across five apps. Half-finished thoughts. A great point from Tuesday's meeting that's gone by Friday.
A "second brain" is a system outside your head where you capture, organize, and retrieve information — so you don't have to hold it all in memory.
AI turns this from a personal productivity project into a five-minute habit. You don't need a folder structure, a tagging system, or a new app. You just need to talk to Claude the way you'd talk to an assistant with a perfect memory for whatever you hand it.
Across this lab, you'll practice the three moves that make up any second brain: capture, structure, and retrieve.
Claude doesn't remember previous conversations by default. Think of each chat as one notebook — everything you want it to work with has to be on the page, either pasted in or said earlier in that same conversation.
Thanks for your feedback!
