A text-based personal agent on iMessage, RCS and WhatsApp — with its own computer, browser and persistent memory
Sundae, from London-listed Sundae Bar AI, is a personal agent you reach by text — iMessage, RCS or WhatsApp. Behind the chat it has its own computer and browser plus a persistent memory, so it can research, book and organise across the web and remember the context next time.
Sundae also watches things for you and sends proactive alerts when something changes. It launched in beta in October 2026, with a waitlist to follow; pricing has not been announced.

Personal agents go further than chatbots: they keep working in the background, use tools, and complete multi-step tasks on your behalf. Choosing one starts with trust and control. Look for clear permission systems — what the agent may do on its own, what needs your approval, and how you revoke access — because an agent connected to your email, calendar and files is powerful in both directions. Channels matter: an agent you can reach by text, call or inside your chat apps fits real life better than another dashboard. Check memory and continuity (does it remember your preferences and past tasks?), the models it can use, and whether it is hosted for you or self-hosted on your own infrastructure. Start any agent on low-stakes tasks, review its work, and widen its permissions only as it earns trust.
