Tiago Forte's CODE method organises the creative process into four timeless stages — Capture, Organize, Distill, Express — run inside one trusted digital note system he calls a Second Brain. The premise is that virtually all knowledge work is inputs processed into outputs, and that nobody can make anything good staring at a blank page. So you build a single central store of raw material — book notes, journal entries, meeting takeaways, packing lists, bookmarks, half-formed ideas — that you know will be preserved and searchable forever. Each stage is deliberately separated in time: capture without judging, organise by where it will be used, distill down to the main point, then express by shipping something into the world. The separation is itself the constraint that makes knowledge work tractable.

How to run it
- 1
Pick one central, trusted place
Choose a single digital notes app and commit to it. The whole system depends on your confidence that when you hit save, the note is preserved forever, searchable, and findable later. Without that trust, capture isn't worth the trouble.
Pro tip Your phone is the notebook you always have on you — treat the app on it as the front door to everything.
Watch out Collecting note-taking apps is not building a Second Brain. Forte and Abdaal both flag becoming 'a hammer enthusiast' rather than a carpenter.

Capture anything with future value
Write down the things you'd otherwise try to keep in mind: quotes, ideas, hooks, meeting points, things to pick up at the hardware store, your kid's homework, places to visit. Don't add a special effort to your life — just record what already passes through it.
Pro tip Scale the unit down until it fits any gap in your day: one sentence, one bullet, or even just the title of a note your future self will fill in.

Organize by where it will be used
File each captured item into the project, area or context where it will actually get pulled out again — the studio build, the chemistry module, the marketing launch — rather than into an abstract taxonomy you'll never search.
Pro tip Project folders double as opportunistic to-do lists: driving past the hardware store, you can open the project note and act on it in seconds.
Watch out Organising while you capture kills both. They are designated times for different kinds of thinking.

Distill to the main point
Revisit saved material and decide what the takeaway is — the main message, the one line worth keeping. You will save far more than matters, so distillation is what makes the archive usable rather than another pile of inventory.
Pro tip Reorganise the note in place when you touch it: promote what's live to the top, push the rest into a 'don't worry about it for now' section.
- 5
Express — ship it into the world
Assemble the output from your raw materials instead of from a blank page: the essay, the video, the report, the memo, the decision. Forte argues the purpose of knowledge is to be shared, applied, and put into your own words so it has an impact on you, your family, your career or your business.
Pro tip Treat decisions as creations too — they draw on stored inputs exactly like a piece of writing does.
Watch out Assembling from a Google search instead of your own store leaves you at the mercy of SEO content, as Abdaal notes in the episode.
In the wild
Forte describes a micro case study from the book. As a new parent he has to use every spare minute, so when he happens to be driving past the hardware store — which is across town — he wants to know within seconds everything he might pick up. He opens his notes, goes to the project folder for the studio they were building, and finds the running list of things to buy. He reorganises it on the spot, promoting some items and pushing others into a 'don't worry about it for now' section. Items he'd never have remembered, and couldn't have reconstructed sitting in the parking lot, get bought on a trip he wasn't planning to make.
→ A spontaneous five-minute detour clears a batch of errands that would otherwise have needed a dedicated trip.
Forte says musicians keep what they call hook books: individual words, turns of phrase, little sentences, and scenes from everyday life — 'I saw someone in red pants get into a red cab.' When it's time to write a song, instead of facing the pressure of inventing something brilliant and original on demand, they open the hook book, piece a few fragments together, find an evocative snippet, and often build the entire song around it.
→ The hardest creative moment — inventing the hook on demand — is replaced by selecting from material already collected.
Common mistakes
Collecting apps instead of creating
Abdaal admits he falls into trying one note-taking app after another and becomes a collector of tools rather than someone who writes and publishes. The tool is a means to an output; if the output never appears, the system is decoration.
Doing all four stages at once
Capturing, organising, distilling and expressing simultaneously is what makes creative work feel overwhelming. Forte's point is that CODE is a set of constraints — designated times for different kinds of thinking — not four things to juggle in one sitting.
Saving where you don't trust it
If you aren't confident the note will still be there and findable later, you stop capturing. Scattering notes across apps, chats and paper destroys the compounding value of one central store.
From the transcript
“And I boiled that down. It's it's amazing how long this took into four steps, capture, organize, distill and express.”
“Things have to be captured, they have to be recorded in some way, shape or form. They have to be organized in some way, categorized,…”
“You centralize it all in one single central place”
