Szn brings a former Siri engineer’s personal AI agent to iMessage

The agent is designed to act, not just answer

Bloomberg reports that szn will be able to browse websites, make purchases and coordinate vendors on a user’s behalf. It will receive its own name, email address and phone number so it can contact people and respond to messages while handling a task.

The company’s product site describes a similar workflow: send a text, voice note, photo or forwarded email, then let the agent make calls, send emails, follow up and return when a decision is needed. That positions szn closer to a remote personal assistant than a question-and-answer bot.

Gupta says each customer will have a dedicated model and that personal data will not be used for training. Those privacy claims come from the company and have not been independently audited in the material reviewed for this story.

Apple integrations are part of the appeal—and the risk

Szn is also designed to collaborate through shared Apple Notes, use Find My location data and work with files stored in iCloud, according to Bloomberg. Keeping those interactions inside iMessage could make the agent feel native to iPhone users even though it is not an Apple product.

That dependence creates an obvious constraint. Apple has previously restricted third-party services that rely on iMessage, and the company has not announced or endorsed szn. The agent’s long-term access could therefore depend on technical and policy decisions outside the startup’s control.

The October launch will provide the first meaningful test of whether the service can safely turn broad instructions into reliable real-world work. Until then, the promised integrations and task range remain company claims rather than independently demonstrated performance.
