Install the software you’ll need

Two apps. Both are free to download; Claude Code needs a paid Claude plan to actually use it.

The page stands alone — every click is in the text. A short screencast of the install will pair with it when recorded.

This page is written from a Mac perspective. Simon’s whole setup is Mac-based, so the steps below name Mac-specific clicks. If you’re on Windows or Linux: Claude Desktop is available for your platform too — same claude.com/download page. Once you have it installed, paste the URL of this page into Claude Code on your machine and say “walk me through this.” The AI will adapt the steps for you.

What you need

Step 1 — Claude Desktop

  1. Go to claude.com/download and run the installer.
  2. Drag Claude to your Applications folder.
  3. Launch Claude. Sign in with your Anthropic account.
  4. Check which account you’re signed in to. A common slip: many people already have a free personal Claude account and also an MMF account through work. Make sure you’re signed in with your MMF email, not a personal Gmail — otherwise nothing in this course will be billed correctly and your usage limits will be much tighter. You can switch accounts from the avatar menu in the top-right.
  5. You’ll see three tabs at the top: Chat, Cowork, Code. Click Code.

If Code prompts you to upgrade, you’re either signed in to the wrong account (see step 4) or that account isn’t on a paid plan yet. DM Simon if you’re stuck.

Why “Code” if you’re not coding?

The name is misleading. Code is the only tab that can read and edit files on your Mac, regardless of whether those files are code, prose, transcripts, spreadsheets, or anything else. The other tabs:

For this course you live in Code.

Step 2 — Obsidian

  1. Go to obsidian.md and download the Mac version.
  2. Drag Obsidian to your Applications folder.
  3. Launch it. On first run it asks you to either open an existing vault or create a new one. Create a new vault. Call it whatever you want — your name, “Notes”, “Vault”, whatever.
  4. Where to put it: pick an iCloud folder. When the file picker comes up, navigate to iCloud Drive (in the sidebar) and create your vault inside there — something like iCloud Drive/Notes/. This means your vault is automatically backed up to iCloud and will sync between your Macs and iOS devices for free. If you put it in Documents or Desktop it’ll work but won’t be backed up unless you’ve explicitly turned that on.

That’s it. The vault is just a folder of .md files; you can move it later if you want to.

ChatGPT (OpenAI’s chatbot) isn’t the main AI in this course — Claude Code is — but it’s a really useful companion for two specific reasons:

Not everyone will need this — if you’re not doing voice-heavy work or AI-assisted coding/analysis, you can skip it for now and pick it up later. Most of us probably will, though.

Plan

Steps

  1. Go to chatgpt.com, sign up (or sign in if you already have a free account), upgrade to Plus.
  2. On the web app: look for the microphone icon in the message bar to dictate. On mobile: the same icon plus a separate voice-mode wave icon for full conversation mode.
  3. Keep ChatGPT in a window next to Claude Code. Dictate into ChatGPT → copy the transcribed text → paste into Claude Code. (A screenshot of Simon’s actual workspace setup will land here when he gets a chance to drop one in.)

Sanity check

These apps run quietly in the background; you’ll be in them most days.

What’s next

The two apps don’t know about each other yet — that’s the next short page. Head to Connect Claude to your notes folder.

If something breaks

  • Desktop app won’t launch (“unidentified developer”): System Settings → Privacy & Security → “Open Anyway”.
  • Code tab shows 403 or asks you to upgrade: you’re either signed in to a free personal account by mistake (check the avatar menu, switch to your MMF account) or that account isn’t on a paid plan yet. Ask Simon.
  • Sign-in loop: make sure your browser isn’t blocking redirects from auth.anthropic.com.
  • Anything else: message Simon on Slack with the exact error text (a screenshot is fine).
