Summary  
This chapter demonstrates how to generate and assign metadata tags to items for categorization and integrate those tags into an existing structured dataset.

General domain of usage  
Personal knowledge management

Tags are what let you find things later without re-reading everything. You don't need to invent a tagging system yourself — ask for one, and see it actually land somewhere real.
 
 ## Task
 Using the same notes from the previous chapter (or a new set), ask:
>
> Suggest 3-5 tags I could use to categorize this note so I can find it again later. Then add it to my Notion page under whichever existing section fits best.

Notice how this ties back to the categories from Chapter 2 in Section 1 — that's the structure of a second brain starting to form.

Master the skills needed to turn scattered thoughts, notes, and meetings into a system you can actually rely on. Discover how to capture ideas without friction, structure raw notes into clear decisions and action items, and retrieve what you need without repeating yourself. Get hands-on experience connecting AI to a Notion page and a calendar, then build a review habit that keeps your second brain alive long after the lab ends.

Learn how to offload thoughts before organizing them, using AI to sort a messy brain dump and surface the ideas worth keeping from anything you read or hear.

Turn raw notes into decisions, open questions, and action items, then build a tagging system connected to a real Notion page so nothing gets buried.

Practice asking follow-up questions that draw on context already shared, then build a review routine backed by a real calendar reminder.
