Nikhil Gupta launches szn, an AI agent that operates within iMessage to browse, purchase, and communicate with merchants on behalf of users. Unlike traditional chatbots, szn performs actions using data from notes and iCloud, with each agent having unique contact details. Currently in early access with expansion planned for October, the service raises questions about its iMessage integration method and privacy permissions. Apple recently approved Poke for business messaging, while Siri gains new app action capabilities, highlighting the evolving landscape of AI agents interacting with Apple's ecosystem and user data.
