All the AI agents that can live in your text messages

Rather than downloading another app, a growing number of agents can simply be texted like an ordinary person. You text it what you need, and it can remember context, connect to the apps and services you already use, and complete tasks on your behalf. This can mean scheduling an appointment, organizing a calendar, researching a trip, sending an email, making a reservation, shopping online, or reminding you about something days later.

While Instinct is one of the buzziest AI agents at present, thanks to its $10 billion valuation after its latest funding round of $1 billion, there are many others also making a play for this space. Below are some of the most notable options so far, from general-purpose personal assistants to agents designed for families, travel, and work.

Caddy is an AI assistant that turns the information scattered across your phone into actionable items. It lives in iMessage for iPhone users and RCS for Android users, so there’s no separate app or inbox to constantly check. For instance, if an email contains an appointment that needs to be added to your calendar or a friend sends a list of things to pick up, Caddy connects to your calendars and conversations, identifying items that may require action. It can add events to your calendar, set reminders, keep track of follow-ups, and even do research for you. Caddy has been available in public beta since April 2026.

Fambot is an AI-powered “chief of staff” for families, designed to organize various aspects of family life, including school communications, sports activities, meal planning, and other day-to-day responsibilities. The service works across both an app and text messages. Fambot automatically sends a summary of the following day every night, including upcoming events and to-dos. Parents can reply to those messages to ask questions or make changes. Currently, Fambot connects to Gmail and Google Calendar, with support for Outlook and Apple Calendar planned for the future. Launched in beta in early September 2026, it has raised $3.5 million in pre-seed funding and is free during the beta period.
