Tab

Pros: What I like most is how little friction there is. I can just text Tab the same way I would text an assistant and ask it to actually get something done instead of giving me a list of instructions. The computer-use side is where it gets really useful. Tab can open websites, work with connected accounts, create files, make phone calls, and keep working after I leave the conversation. That makes it useful for things like reservations, travel changes, purchases, research, and random admin tasks that normally eat up time. I also like the payment approval flow. Tab can prepare a purchase or booking, but I still see the exact amount and recipient before anything gets paid.

Cons: The main downside is that I would still be careful about how much access I give it. Tab has clearly thought about security — credentials and payment details are kept outside the normal AI context, and uncertain actions are supposed to stop rather than repeat automatically — but an agent this capable still deserves supervision.

Overall: Overall, Tab feels much closer to a real personal assistant than a traditional chatbot. The combination of texting, computer use, phone calls, memory, payments, and background task execution makes it one of the more practical agent products I have tried.
