Second Brain

Your notes are not the problem. You already write things down — meeting notes, half-finished thoughts, screenshots, voice memos, a Notion page you abandoned. The problem is that nothing ever *reads* them back to you. They pile up. They go cold.

A second brain is one place that reads everything you've ever put in, connects it, and answers questions you didn't know you could ask. You don't organize it. It organizes itself. [Make this to wiki. Overview page must contain all this seque]

Follow these steps to get your second brain running. See How to Set Up Your Second Brain (6 Steps) for the full detail.

1. 1.Sign up. Go to the site and create an account. Free to start.
2. 2.Create a wiki. Give it a name — your whole life (My Brain), or one slice (Work, Grad school, Q3). Start with one and let it get messy.
3. 3.Click Templates.
4. 4.Choose "Second Brain." This gives you a starting structure. You don't have to follow it — it bends around whatever you put in.
5. 5.Drop your files in. Not the clean ones — *all* of them. See What to Feed Your Second Brain below.
6. 6.Ask it something. This is the part people rush. See Part 3.

The mess is the signal.

Most people's first instinct is to clean up their notes before uploading. Don't. Half-finished sentences, the same worry written three times, a thought you crossed out — that's the texture a second brain actually reads. A tidy note tells it what you *decided*. A messy note tells it what you're *still deciding*.

Good things to feed it that people forget:

• Meeting recordings — upload the audio; it transcribes and separates who said what
• Your junk-drawer note — the one with groceries, a book quote, and a 2am thought all in a row
• Old projects you gave up on — they connect to new ones more often than you'd think
• Other people's documents — reports, specs, a contract you don't fully understand

The mistake is asking for a summary. Every AI does summaries. A second brain's whole value is that it can see across your sources — connecting things you wrote months apart, in different files, and never put side by side yourself.

Ask it questions only something that read *everything* could answer:

Rule of thumb: if a question could be answered by one document, you're wasting it.

See Second Brain: Tips That Make It Work for the full detail. A summary:

1. 1.Don't clean first. Upload the raw thing.
2. 2.Keep adding. It compounds. The value curve is not linear — it bends when sources start referring to each other.
3. 3.Name speakers before you compile. When you upload a recording, rename Speaker 1 / Speaker 2 to real names *before* compiling. Renaming afterwards won't rewrite pages already built.
4. 4.Ask across everything, not just one wiki. Your best insights live *between* your wikis.
5. 5.Every claim is traceable. When it tells you something, it cites the source file. Click it. Read the original. Never trust a second brain you can't audit.
6. 6.Turn an answer into a thing. A good answer shouldn't die in a chat window — export it as a slide deck, document, or PDF.
7. 7.Re-ask the same question in a month. Same question, more sources, different answer. That's the whole point.

See Second Brain: Frequently Asked Questions for the full list. Key answers at a glance:

• Do I have to organize it? No. You dump, it builds.
• What if my notes are embarrassing? Then they're good notes. Private by default.
• How long does setup take? Minutes. Dropping files is the only work you do.
• What if I already use Notion / Obsidian / Apple Notes? Keep using them. Pull them in here. This isn't a replacement for where you write — it's the thing that finally reads.
• Is it just search? No. Search finds the file you already remember. This tells you the thing you forgot you knew.
