How do I keep track of everything I create with AI?
Short answer
Build a simple second brain: one home you already open, with a three-line entry for every AI output worth keeping. Write what it is, where the file lives, and one sentence on what it is for. Start today by indexing your last five outputs, then add to it each time you finish something.
Three weeks ago I built something in a working session that I knew was good. Last Tuesday I went looking for it. I knew the idea. I could not find the file. The idea was right there in my head and completely out of reach.
That is the part nobody warns you about with AI. Producing good work stopped being the hard thing. Finding it again became the hard thing.
Why does AI work disappear?
The work you make with AI disappears unless you build the system that remembers it. A second brain is how you own your thinking instead of renting it one session at a time.
AI lets you generate ten strong things in a week, and the speed is exactly what buries them. The more you make, the deeper the good stuff sinks. The usual response is to make more. The real return comes from capturing what you already made so you can use it twice, then ten times.
What does a second brain look like in practice?
It is smaller than you expect. Pick one home: Apple Notes, a single Google Doc, Obsidian, whatever you will actually open. Every time you finish something worth keeping, you write three lines:
- What it is
- Where the file lives
- One sentence on what it is for
No tags to design. No app to learn.
Three lines is deliberate. It is short enough that you will write it when you are tired at the end of a session, and specific enough that a search for the idea brings back the file. Anything longer becomes a chore you skip. Anything shorter leaves you with a title and no idea where the work went.
Pick the home you already check every day. A plain note you open each morning will serve you better than a beautiful system you visit once a month, because the entry has to be there when you go looking.
Who gets the most out of this?
The best operators I work with can find what they made in February and use it again in June. Every piece of work you can find again is work you do not have to pay for twice.
That is the compounding part. Each entry makes the next search faster, and each reuse makes the original session worth more than the hour it took. The index you start today is the one you will be grateful for when you go looking in a few months.
Do this today
Ten minutes, one note.
- Open one note, title it "Second Brain Index," and add your last five AI outputs as three-line entries.
- Tomorrow, add to it.
When you finish, you will have a searchable spine for everything that used to vanish.
Meredith's rule
The work you make with AI disappears unless you build the system that remembers it.
Questions
What is a second brain for AI work?
It is one place where you log every AI output worth keeping, so you can find it later. Each entry has three lines: what it is, where the file lives, and what it is for. It needs no special app or tagging system.
What app should I use for a second brain?
Use whatever you will actually open: Apple Notes, a single Google Doc, or Obsidian. A plain note you check daily serves you better than an elaborate system you rarely visit. The habit of logging each output counts for more than the software.
How long does it take to set up a second brain?
About ten minutes to start. Open one note, title it Second Brain Index, and add your last five AI outputs as three-line entries. After that, you add one short entry whenever you finish something worth keeping.
