Install Otto
Your key, one line, done.
Your confirmation email has the two things you need: your product key and the install line. Here is the whole install, start to finish.
On a Mac
Three steps in Terminal
Open Terminal
Press ⌘ Command + Space, type Terminal, and press Return.
Paste the install line and press Return
Paste your product key, then pick a name
When it asks for your product key, paste the key from your email. Dashes or no dashes, it reads it either way. Then press Return to keep the name Otto, or type a name you like.
On Windows
Same steps, in PowerShell
Open PowerShell
Open Start, type PowerShell, and press Enter.
Paste this line and press Enter
Paste your product key, then pick a name
The same two questions as on a Mac: your key, then a name. Enter keeps the name Otto.
What you will see
Otto checks his own setup
Ready. Otto joined your Claude Code team, got a browser to work in, and proved it with a first small win.
Optional extras, like GoHighLevel, Zapier or Make. The line under each one says how to turn it on when you want it.
If your key includes n8n, you may see FIX next to the n8n key. That is only your n8n API key: Otto asks for it the first time you give him an n8n job.
The last line says Installed. That is it.
After install
Tell Otto what you want done
Open Claude Code (or Codex) and ask in plain words. He finds a way to do it.
To update Otto later, run the same install line again. Your key is saved on your computer in ~/.jtl/product.key (on Windows, .jtl\product.key in your user folder).
Help
Something not green?
The installer prints the one fix on the line under any item that needs you. Run that, then run the install line again.
