How to build a second brain in 10 minutes

Most second brain guides start with a warning: this will take time to set up. Choose your tool. Design your folder structure. Decide on your tagging system. Set up your PARA categories. Create your templates. Configure your capture workflows. The setup takes a weekend. The tweaking takes another weekend. By the time you're "ready," you've spent more time building the system than using it, and the maintenance has only just begun.

Here's the 10-minute version.

Minutes 1-2: Create your library

Sign up for Fabric and you have a library. That's it. No folder structure to design. No database schema to plan. No tags to define. The library is where everything goes, and smart organisation handles the categorisation that traditional methods ask you to do manually.

Minutes 3-4: Install the capture tools

Install the web clipper in your browser. Save any article or webpage to your library with one click. Install the mobile app or desktop app for capturing on the go: voice memos, photos, quick notes.

Set up email forwarding so you can send things to your library by email. Enable screenshot sync if you capture ideas as screenshots.

Minutes 5-7: Connect your existing sources

This is where the 10-minute version diverges from the traditional approach. Instead of manually importing years of accumulated content, connect the tools where your content already lives.

Google Drive: your documents, spreadsheets, and presentations become searchable. Dropbox: same. Email: important messages and attachments become part of your library. Readwise: your book and article highlights flow in. Notion: your existing notes become searchable by meaning.

Each connection takes about a minute. The content starts indexing immediately. You don't move anything. It stays where it is and becomes searchable from your library.

Minutes 8-9: Add your first captures

Save an article you've been meaning to read. Record a voice memo with an idea you've been carrying around. Write a quick note about something you're working on. Clip a webpage for reference.

Each capture takes seconds. The library is now populated with your first items alongside everything flowing in from your connected sources.

Minute 10: Search it

Try a search. Not a keyword search, a meaning search. "That article about how teams communicate differently when they're remote" or "the thing I was reading about pricing" or "my notes from last week." Semantic search finds what you're looking for based on what it means rather than what you called it.

Your second brain is working. It will get more useful every day as you add more content, because each new capture creates more connections and more retrieval paths for the search and the AI assistant to draw on.

What you didn't have to do

No folder structure designed. No tagging system decided. No PARA categories configured. No templates built. No linking strategy developed. No progressive summarisation workflow established. No weekend lost to setup.

All of that is either handled automatically (smart organisation, semantic search) or available when you want it (spaces, tags, canvas) without being required for the system to work.

The traditional second brain asks you to build the infrastructure before you can use it. This approach asks you to use it and lets the infrastructure build itself.

Frequently asked questions

Will I regret not setting up a proper structure? The search handles retrieval regardless of structure. As your library grows, you might want to create spaces for major projects or life areas, and you can do that at any time. But the library is useful from minute one without any structural decisions.

What if I've already built a second brain in Notion or Obsidian? Connect it. Your existing content becomes searchable by meaning alongside everything new you capture. You don't have to abandon what you've built. You add a search and AI layer on top of it.

How does this compare to the traditional BASB approach? The traditional approach front-loads the organisational work. This approach eliminates it. Both capture and retrieve. The difference is whether the organisation happens manually (traditional) or automatically (Fabric). The detailed comparison covers the specific differences.

What should I capture first? Whatever you're working on right now. Save the articles you're reading this week. Record your next meeting. Clip the reference material for your current project. The second brain is most immediately useful when it contains the things you need today, and it grows from there.

Does this work offline? The desktop app and mobile app support offline access to your library. Content syncs when you reconnect. You can capture voice memos, write notes, and browse your library without an internet connection.
