-- Anthropic (Claude)
-- Google (Gemini)
-- Configuration: Update `.env` with appropriate API keys
+The application uses a simple API key management system:

+- Configure via Settings > API Keys in the app
+- Falls back to `.env` OPENAI_API_KEY if not configured
+- Realtime Agent checks for API key on startup
