Session Introduction

Set the frame for what you will build, what you need to install, and how the hands-on session will work.

2:30-3:00

Intro to Second Brains

Understand what an AI Second Brain is: a personalized working partner that remembers your context, reflects your judgment, and helps you think through real work.

3:00-3:30

Intro to Codex

Learn the Codex app basics: how to talk to it, how to use plugins, and how to start turning your own context into usable AI support.

3:30-4:00

Personalizing Your Second Brain Setup, Part 1

Install the quickstart plugin and begin shaping your Second Brain around your own work, decisions, communication style, and recurring responsibilities.

4:00-4:30

Personalizing Your Second Brain Setup, Part 2

Continue building out your setup with Kora-style personalization: your priorities, judgment patterns, and the places where AI should help rather than merely summarize.

4:30-4:45

Use Case Ideas

Explore where your Second Brain can help with decisions, meeting prep, stakeholder updates, governance notes, and follow-through.

4:45-5:00

Session Wrap-up

What You Are Building

Hour 1

Codex App, Basic Commands, And The Seeds Of Your Second Brain

You will learn how Codex works, what the quickstart plugin gives you, and how a Second Brain starts with concrete context rather than a blank chat window.

Hour 2

Personalization, Kora, And Your Working Patterns

You will start building Kora: a personalized assistant that learns how you think, decide, communicate, and follow through.

Hour 3

Hands-On Setup And Growing The System Over Time

You will bring real work into the setup and learn how your Second Brain improves through use, correction, and better context.
