Signal runs entirely in your browser and calls Claude directly using your own API key — no account, no backend, nothing stored anywhere but this browser.
Claude API key
Stored only in this browser's local storage. It's sent straight to Anthropic when you use the tool — never to us, never anywhere else.
Don't have a key yet? Get one at console.anthropic.com — API usage is billed separately from any Claude.ai subscription.
