A new category of AI agents is bypassing standalone apps entirely, working instead through the text-messaging interfaces people already use. According to TechCrunch's roundup, these assistants can remember context, connect to existing apps, and complete tasks such as scheduling appointments, sending emails, or making reservations. The space is attracting significant capital: Instinct, one of the buzziest names, raised $1 billion in September 2026 at a $10 billion valuation, after an earlier round that valued it at $2.5 billion.

The article profiles several notable entrants. Caddy, in public beta since April 2026, lives in iMessage and RCS, turning scattered phone data into calendar events and reminders. Comma is an open-source option that works across browsers and files, reachable through Signal, Telegram, and WeChat. Fambot targets families, sending nightly summaries of the next day's schedule and connecting to Gmail, Google Calendar, Outlook, and WhatsApp. Folk, available via iMessage, WhatsApp, and Telegram, runs on a private cloud computer and can execute multi-step tasks.

Pricing varies widely. Folk offers a free tier and a Pro subscription at $8.33 per month, while Martin, a general-purpose assistant, starts at $21 per month. Fambot is free during its beta but expects to charge roughly the equivalent of a Netflix subscription later. Instinct remains in private beta, though it has begun giving users dedicated email addresses and rolling out call support. The article also notes that such autonomy raises privacy and security concerns, a caveat that applies across the category.
