Best AI assistants you can text in 2026 (iMessage and SMS)

The best interface for an AI assistant turns out to be the one you've used every day for twenty years: a text thread. No new app to install, no tab to remember to open, no prompt-engineering ritual. You text the assistant like a person, it answers like a person, and — if it's any good — it goes off and does the thing.

"Any good" is where the field splits. Some texting assistants are a chatbot behind a phone number: fun, but all talk. The interesting ones connect to your email, calendar, and tools, and come back with finished work. Here's the honest map of the category in July 2026, including where our own product sits.

How we judged: four things separate these products — the channels they truly live in (iMessage vs SMS vs both), whether they take real actions in your tools or just chat, whether they can touch a phone call, and who they're built for (you personally, or your team's work). Every claim below comes from each product's own public materials, checked July 2026.

Arlo — text it like a colleague, not a chatbot

Arlo is an AI colleague for work that treats texting as a first-class surface, not a gimmick. You text it from iMessage or SMS the way you'd text a capable teammate: "chase the Hendricks invoice," "move my 2pm," "what changed overnight?" It reads the tools behind the request — Gmail, Slack, Notion, Linear, your CRM among 3,000+ integrations — does the work, and asks approval before anything consequential goes out. It also makes and takes live phone calls, which no pure-text assistant does, and it carries one persistent memory across your texts, Slack, Teams, and calls, so context never resets when you switch channels. Governance is on by default: approval gates, policy checks, and a full audit trail per run. It starts free, with usage tiers at $20, $100, and $200 a month.

The honest caveat: Arlo is built for work. If you want an assistant purely for your personal life, the next two entries are shaped for that.

Poke — the personal pick for iMessage

Poke lives in iMessage, WhatsApp, and Telegram, connects to your email, calendar, and around 30 personal apps, and runs your life admin with one-tap "recipes." Its tagline — that it fits into your life, not the other way around — is accurate, and its texting UX is genuinely polished. It's built around one person, with Free, Pro, and Ultra tiers. For personal use it's a strong pick; for team work it isn't trying to compete. Full breakdown: Arlo vs Poke.

Martin — the Jarvis pitch, over SMS and calls

Martin markets itself as a personal AI like Jarvis: it texts over SMS and WhatsApp, manages your calendar and inbox, sets reminders, and can make calls. It leans consumer — busy professionals, students, anyone who wants life logistics handled from a thread. It's the most direct personal-assistant analog to Arlo's texting surface, without the team, governance, or deep tool layer. Full breakdown: Arlo vs Martin.

Catch — proactive, across your channels

Catch reaches you over Slack, email, text, and phone, and is deliberately proactive — nudging you about what needs attention rather than waiting to be asked. It's aimed at one person's workload. If "assistant that texts first" is the feature you want most, Catch does that well. Full breakdown: Arlo vs Catch.

Lindy — automation you can reach by text

Lindy comes at texting from the workflow side: it's a build-your-own-agents platform for business automation (inbox triage, scheduling, multi-step processes) that you can also reach over iMessage and email. If you want to design repeatable flows and then talk to them, it's a strong pick; if you want to delegate messy one-off work in plain language, the builder mindset is overhead. Full comparison: Arlo vs Lindy.

Sidekicks and Tomo — the iMessage-native field

Two smaller products worth knowing, per their public materials as of July 2026. Sidekicks works over both iMessage and SMS with group-chat support and switchable personas (assistant, health coach, companion) — the easiest pure-chat experience, lighter on real tool actions. Tomo is a proactive iMessage assistant that joins group chats and connects to your calendar, email, and Notion — closer to Poke's personal-life lane than to a work tool. Both are credible if the job is personal texting; neither is built for a team's tools, approvals, or phone lines.

The bridges — ChatGPT in your Messages app

A cluster of small products wires ChatGPT-style models into iMessage: text a number, get model answers back. They're the easiest way to try AI-by-text and some support group chats. The limitation is structural: they're chat interfaces, not assistants — most can't touch your calendar, inbox, or tools, so nothing gets done. Good for questions; not a colleague.

How to choose

One question does most of the work: is the job personal or professional? Life admin — Poke or Martin. One person's proactive workload — Catch. Work that touches a team's tools, customers, and phone lines — Arlo. And if you just want answers in iMessage, a bridge app is free-ish and instant.

Frequently asked questions

What is the best AI assistant you can text? For work, Arlo — it handles real tasks across 3,000+ tools from an iMessage or SMS thread, with approvals and an audit trail. For personal life admin, Poke and Martin are the strongest picks.

Can I text an AI assistant without installing an app? Yes. Texting-first assistants like Arlo work over iMessage and SMS directly — you text a number like a person. No download, no new interface to learn.

Do any texting AI assistants also make phone calls? Arlo and Martin both place calls. Arlo places and takes live calls for work — confirming, chasing, fielding — then summarizes the call and updates your records.

Are AI texting assistants safe to connect to email and calendar? Look for explicit governance: scoped access, approval before sends, and an audit trail. Arlo ships all three on by default; personal assistants vary, so check each product's security page.

What's the difference between a texting chatbot and a texting assistant? A chatbot answers in the thread. An assistant leaves the thread — reads your tools, takes the action, and reports back. If it can't touch your calendar, inbox, or apps, it's a chatbot with a phone number.
