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

Caddy

Caddy is an AI assistant that turns the information scattered across your phone into things you can actually act on. 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, an email contains an appointment that needs to be added to your calendar or a friend sends a list of things to pick up. Instead of worrying about all the details getting buried, Caddy connects to your calendars and conversations, then identifies 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

Comma is designed to manage tasks across both work and everyday life. Comma 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.

It 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, and can deliver daily briefings, flag urgent matters, and summarize recorded calls.

Comma is free to start and open source.

Fambot

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, and turn them into an organized plan.

The service is designed to work across both an app and text messages. Fambot is available on iOS devices, Android devices, and the web, and families can also 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.

Folk

Folk is designed to be an AI assistant you can reach through iMessage, WhatsApp, and Telegram. It can remember personal context, manage reminders, research topics, track flights, handle email, and perform real-world tasks such as restaurant reservations.

One distinction is that Folk runs on its own private cloud computer. It can also run code and execute multi-step tasks rather than merely responding conversationally.

Folk launched its beta in May 2026, and it’s available for free but also offers a Pro subscription for $8.33/month if you want unlimited tasks running in the background.

Instinct

Instinct first made headlines after raising $350 million at a $2.5 billion valuation. In September 2026, it raised $1 billion, valuing it at $10 billion.
