Turn the agent on, then press Greeting when a Spanish-speaking customer walks up.
The key stays on this phone only. It is sent to Anthropic and nowhere else. Set a monthly spend limit for it in the Anthropic console.
Privacy: the conversation is kept in memory only and cleared with End visit or after 15 quiet minutes. Phone numbers and emails are removed before anything is sent. The microphone uses Chrome's speech service (audio goes to Google); the typed or spoken text then goes to Anthropic with your key.
