Top AI Agents Live in Text Messages to Complete Tasks

A new wave of consumer AI assistants is competing by entering conversations users already have, rather than asking them to install standalone apps. These agents operate through SMS, iMessage, RCS, WhatsApp, Telegram, Signal and email, connecting to calendars, inboxes, files and services to schedule appointments, manage reminders, research options, shop, make reservations, call businesses, track flights and complete multi-step tasks. Instinct is one of the most closely watched entrants. The company raised $1 billion in September 2026 at a $10 billion valuation after an earlier $350 million round at $2.5 billion. Its assistant can communicate by text or voice, integrate with email, calendar and Google Workspace, and began issuing dedicated email addresses so it can create accounts, contact businesses and follow up without using a user’s personal inbox. It is also rolling out calling support, though its autonomy has raised privacy and security concerns. Other general-purpose assistants take different approaches. Caddy works in iMessage and RCS, extracting actions from messages and calendars. Comma operates across browsers, computers, files and messaging apps while remaining open source. Martin provides daily summaries and can send messages or make calls from $21 per month. Maverick asks permission before acting and offers a Pro tier at €27 per month. Tab emerged from stealth in October with a $300 million valuation. Underdog launched an invite-only beta that runs locally on Mac and Windows to keep data on the user’s device. Family-focused agents consolidate school communications, activities, meals and chores. Fambot launched in beta in September 2026 after raising $3.5 million pre-seed and sends nightly summaries over SMS. Ollie, launched in June, is notable for achieving SOC 2 compliance among mainstream family assistants, with paid plans from $25 per month. Orbits, backed by a16z Speedrun fund, combines calendars, purchases, reservations and household coordination. Ohai charges from $9.99 per month, while Iris and Tomo offer group-chat and iMessage interfaces. Specialized assistants are also emerging. Miso combines iMessage trip planning with a human travel team. Town raised a $55 million Series A in June 2026 for an assistant aimed at recurring work tasks across email, documents and Slack. Ask Proxy markets a proactive personal agent at $1 per day and business plans from $15 per employee per month. Wajo’s Fo launched publicly in September 2026 with its own email, phone number and payment card, and can escalate tasks to humans. Poke was approved by Apple in June as the first AI agent on Apple Messages for Business and acquired a month later by Cognition in a low nine-figure deal. Skye raised $3.6 million to build an agentic homescreen, while Stanley targets content creators. The common pitch is simplicity: users text a request, and the agent remembers context, checks connected services and completes the job. The race is now defined by reliability, autonomy, privacy and how far assistants can act on a user’s behalf.
