Three steps to start

1

Download & install

Open the downloaded .dmg file and drag Quiddy to your Applications folder. First launch may require right-click → Open to bypass Gatekeeper on first run.

2

Add an API key

Open Settings → API Providers and add your key from Anthropic, Google, or OpenAI. Keys are stored in the macOS Keychain — never in plain text. Or use Floodgate if on Apple internal network.

3

Complete first-run setup

The guided wizard asks your name, what you work on, and helps you pick a starting persona. Your context is injected into every conversation from that moment forward.
