If a shared API key is configured on this site, Ask mode works for everyone with no setup.
Leave the field below blank to use it. Set your own key only if you want to use your own Anthropic billing.
Your API key is stored in your browser only (localStorage) and sent directly to Anthropic — it never leaves your machine except to call the API.
Get a key at console.anthropic.com.
