Best iMessage AI Assistants You Can Text

The best AI assistant is the one you'll actually use, and for most people that means the app that's already open more than any other: Messages. The agents here work over a plain text thread — no download, no new login, no tab to forget about. You text them the way you'd text a capable friend, and they text back.

We ranked these on how well they hold up as a daily driver: memory that persists between conversations, the range of things they can actually do (calendar, email, reminders, reservations, research), and how proactively they reach out versus waiting to be asked. Poke leads because it's genuinely proactive — it'll nudge you about a flight or a follow-up before you think to — and it works across iMessage, WhatsApp, and Telegram. Notis behaves like an eager intern you delegate to. Sidekicks and textmyagent.app get you running over SMS with nothing to install. iChatWithGPT, Olly, and Homer AI put a familiar chat model one text away, and folk leans toward the useful-friend errands.

None of these replace a laptop for heavy work. All of them beat opening an app when you just need something handled. Text two or three and see which one sticks.
