What's really happening when AI enables active systems instead of passive storage? The common story is second brains are just better note-taking — but the reality is more complicated.

In this video, I share the inside scoop on building an AI second brain with Slack, Notion, Zapier, and Claude or ChatGPT:
- Why traditional storage systems fail for 19 out of 20 people
- How AI loops classify, route, and surface information automatically
- What eight building blocks make second brain systems actually work
- Where engineering principles translate into no-code automation for non-engineers

Chapters:
00:00 - Introduction: Why Your Brain Needs a Second Brain
02:18 - What Changed in 2026: Active vs Passive Systems
04:34 - The AI Loop: Classification, Routing, and Surfacing
