Second Brain, explained
=======================

An interactive guide to "second brains": what they are, why they matter now,
and how to start one. https://secondbrain-explained.pages.dev

Run it on your computer
-----------------------
1. Unzip this folder.
2. In a terminal, go into the folder and start a small web server:
     python3 -m http.server 8000
3. Open http://localhost:8000 in Chrome or Edge.

(Opening index.html directly also works for reading, but offline mode and
the on-device "Smart AI" need it to be served as above.)

Make it yours
-------------
- index.html  : the words and structure of every chapter
- styles.css  : the look (fonts, colours, layout)
- app.js      : the interactions, the guide's answers, and the on-device AI
Edit the text in index.html, or the guide's answers in app.js (search for
"const CARDS"), then reload the page.

Everything runs in your browser. Nothing you type is sent anywhere.
