The brain

Kids, that spreadsheet was a building with no blueprint. I split it into three tabs, and now it stands on its own.

— Ted

Settings › Brain decides where Ted's thinking runs. You can switch any time.

Claude CLI or Anthropic API

Option	How it works
Claude CLI	Ted uses the claude command-line tool you are signed in to, on your Claude subscription. No key to paste
Anthropic API	Ted calls the API with your key, and you pick the model. Billed to your key

The API key is kept in the macOS Keychain; the daemon gets a copy when it needs it.

Tools: ask first or auto-approve

Tools, in the Engine room section of Settings, decides whether Ted asks before using a tool (running a command, sending a message, clicking) or goes ahead. Ask first is the careful setting.

Personality

How much Ted Mosby goes into Ted's replies:

• The real Ted: architect, storyteller, hopeless romantic.
• Low-key: warm and precise, with a nod to the show once in a while.
• Off: straight answers.

Messages Ted sends as you, on WhatsApp or e-mail, never carry his personality. They sound like you.

The power bill

The Brain sheet also shows what Ted's thinking has used, by model.

Heads-ups

Ding when Ted replies plays a short sound when an answer lands while you are elsewhere.
