Top 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 include 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 the most notable options so far, from general-purpose personal assistants to agents designed for families, travel, and work.

Ask Proxy’s biggest differentiator is that it “thinks like a woman,” meaning it aims to anticipate your needs before you even ask, as explained on its website. It works like a chatbot you can text like a friend, whether you need gift ideas, help planning an event, or recommendations for things to do that weekend. You can ask it to add important dates to your calendar, set reminders, or help with everyday decisions. You can also send it photos, like an empty table, to figure out how to decorate the table for a dinner party. Unlike a typical chatbot, Ask Proxy also takes a proactive approach. It can reach out when it notices something you might forget or when it comes across a new activity, restaurant, or experience you might enjoy.

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 things 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.

Comma is designed to manage tasks across both work and everyday life. It carries tasks through to completion, checking its own work and determining when a task is finished. Completed work is surfaced for review when a decision or approval is needed. It also proactively notifies users and recommends the next steps. Comma can work across a user’s browser, computer, and files, while remaining accessible remotely through messaging apps such as Signal, Telegram, and WeChat. Comma maintains context and memory across devices and conversations, delivering daily briefings, flagging urgent matters, and summarizing recorded calls. Comma is free to start and open source.

Fambot is an AI-powered “chief of staff” for families, designed to bring together the many moving parts of family life, including school communications, sports activities, meal planning, calendars, and other day-to-day responsibilities. The service works across both an app and text messages. Fambot is available on iOS, Android, and the web, and families can interact with it directly over SMS. Every night, Fambot automatically sends a summary of the following day, including upcoming events, to-dos, and details such as school uniform or packing requirements. Parents can reply to those messages to ask questions, check information, or make changes to their calendar. Fambot currently connects to Gmail, Google Calendar, Outlook, and WhatsApp, with support for Apple Calendar planned for the future. The company launched in beta in early September 2026 and has raised $3.5 million in pre-seed funding. The service is currently free during the beta period, but Fambot expects to eventually charge roughly the equivalent of a Netflix subscription.
