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

The best interface for an AI assistant turned out to be the one you've used every day for twenty years: a text thread. You don't install anything or remember to open a tab. You text it 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 of these are a chatbot behind a phone number, fun to talk to and not much else. The useful ones connect to your email and calendar and come back with finished work. A lot changed this summer, too. Cognition bought Poke's maker, Lindy relaunched as a Slack teammate, Catch launched, Instinct went viral with a waitlist, and OpenAI shipped a way for ChatGPT to send iMessages from a Mac. Then the autumn moved faster: Meta launched its Muse agent, Instinct raised $1 billion, Pally made every feature free, and Hark Pro launched as an app. This is where things stand in October 2026. We make one of these products (Arlo), so read our section with that in mind. We also asked ChatGPT's model which assistants it names; here's what it said.

We compared four things: which apps you can actually text it from, whether it does anything in your tools or only chats, whether it can handle a phone call, and whether it's built for your personal life or your work. Every claim about another product comes from that product's own site and dated reporting. Pally, Instinct, Muse and Hark Pro were checked as of October 2026; the rest as of September 2026. We mostly describe pricing by structure instead of dollar amounts, because prices change faster than this page will.

Arlo: for when the texts are about work

Arlo is an AI colleague you text from iMessage, SMS or WhatsApp the way you'd text a capable teammate. "Chase the Hendricks invoice." "Move my 2pm to Thursday." "What changed overnight?" It looks in the tools behind the request (Gmail, Slack, Notion, Linear, your CRM, and about 3,000 others, plus sites with no API through a browser session you sign into once), does the work, and tells you what it did. It asks first when a request is unclear, would spend your money, or can't be undone.

A typical exchange is short. You text "the Hendricks invoice is two weeks late, can you nudge them?" Arlo finds the invoice in your inbox, drafts a polite follow-up to the right person, shows it to you, and sends it when you reply "send". It also makes live phone calls, and it texts you first with the briefs and reminders you ask for. One memory carries across your texts, Slack and calls, so context doesn't reset when you switch channels, and every run lands in an audit trail.

It's free to start with no card, then runs on monthly plans from $20. Pricing has the details.

The caveat: Arlo is built for work. If what you want is help with errands, family logistics or a nudge to drink water, Pally, Poke and Martin are built for that.

Pally: a personal assistant with the widest channel list

Pally is the closest product to Arlo on this list and the one most worth comparing directly. It works over iMessage, Android RCS and SMS through Google Messages, and Telegram, can read your WhatsApp inbox and send replies there, connects to Gmail, Outlook, Google Calendar, Notion, Linear, Slack, GitHub and Jira, books flights, hotels and restaurants, and checks out with your approval. Since 6 October 2026 every feature is free for everyone, with one usage limit that refills through the week; calls, its own phone number and its own email address are included, and the old paid tiers are gone apart from an invitation-only VIP plan (Pally's terms). It pitches itself at both personal and professional use. The difference is emphasis: Pally is organised around one person's loose threads; Arlo is organised around work that other people depend on, with approval gates on sends and writes and an audit trail you can hand to someone else. Full breakdown: Arlo vs Pally.

Poke: the personal pick, now part of Cognition

Poke lives in iMessage, SMS and Telegram, with WhatsApp in some markets, connects to your email, calendar and 30-plus personal apps, and runs life admin through one-tap "Recipes." Its texting experience is polished. On 23 July 2026 Cognition, the lab behind the Devin coding agent, acquired The Interaction Company, Poke's maker; Poke keeps running, and reporting at the time said nothing would change immediately. It's built around one person, with a free tier and paid plans. For personal use it's a strong pick; for team work it isn't trying to compete. More: Arlo vs Poke and what the acquisition means.

Martin: the Jarvis pitch, over SMS and calls

Martin markets itself as a personal AI like Jarvis: it texts over SMS and WhatsApp, now also works in Slack and email, manages your calendar and inbox, sets reminders, and makes calls for you. It's aimed at busy individuals, like professionals, students, and anyone who wants life logistics handled from a thread, and it's a subscription with a free trial. Of everything here it's the most direct personal analog to Arlo's texting surface, without the team, governance, or deep tool layer. Full breakdown: Arlo vs Martin.

Catch: the executive assistant that calls

Catch, covered at launch in early September 2026, is an assistant for executives and leaders at mid-sized companies. Its homepage still shows a waitlist, so check availability. It runs over iMessage, WhatsApp, Slack and email, handles scheduling, inbox, travel booking and forms, places outbound calls, and is proactive by default. It sells one flat subscription with a trial. If you're an executive who wants a single assistant that reaches out first, it's a serious option. Full breakdown: Arlo vs Catch.

alfred_: for people who bill their time

alfred_ is a texting assistant over iMessage, SMS and RCS for founders, lawyers, agents and accountants. It works across Gmail or Outlook, your calendar, tasks and notes, and asks you to approve every send. It offers an individual plan and a per-seat team plan. It doesn't list phone calls or WhatsApp.

Lindy: now a Slack teammate you can also text

Lindy relaunched in August 2026 as a teammate that lives in Slack first, and is also reachable over iMessage and email. It connects to over 1,000 tools, asks for approval before anything with outside impact, and joins Meet, Zoom and Teams calls. It's sold per seat on credit-based plans. If your team already lives in Slack and wants a per-seat agent, it's a real alternative; if you mostly want to text an assistant from your phone, it's Slack-shaped. Full comparison: Arlo vs Lindy.

Instinct: invite-only for now

Instinct went viral in late August 2026: an assistant you text over iMessage, SMS or WhatsApp, or call, that runs a computer in the cloud to carry errands through. On 28 September it raised $1 billion at a $10 billion valuation (TechCrunch), and it now joins group chats in early access. As of October 2026 it's still invite-only, with five invites per member and a waitlist for everyone else, free while in early access, and licensed for personal use by its terms. If you're waiting on an invite, see Instinct alternatives you can use today, or how it stacks up against Meta's agent in Instinct vs Muse.

Muse: Meta's agent, textable on WhatsApp

Muse is Meta's AI agent, launched on 8 September 2026 and separate from the Meta AI assistant built into its apps. You use it in its own app on iPhone, iPad, Android, the Mac and the web, or connect it to WhatsApp and text it there. As of October 2026 it's available only in the US and Canada, to adults. It runs errands on a cloud computer with a browser you can watch, connects to email, calendar and shopping sites, and is free with a weekly usage limit, with Power ($20 a month) and Max ($100 a month) plans for more (Meta). By default it asks before some actions, not all of them. It passed five million downloads within a month, and it has also drawn the most privacy reporting of anything here. More: Muse alternatives.

Sidekicks and Tomo: the consumer iMessage field

Two smaller products worth knowing. Sidekicks works over iMessage and SMS, including group chats, with switchable personas (assistant, health coach, companion) and a limited free allowance before its paid plan. It's the easiest pure-chat experience and light on real tool actions. Tomo is a proactive iMessage assistant with a companion app, pitched around personal goals and accountability; it connects to your calendar, email and the web, on a paid subscription. Both are credible for personal texting; neither is built for a team's tools, approvals, or phone lines.

ChatGPT and the bridges: AI inside your Messages app

Since 20 August 2026 the ChatGPT desktop app can read, search, draft and send iMessages from an Apple silicon Mac, asking before each send by default. That's useful, but it's a different thing from everything above. You can't text ChatGPT from your phone. It works on your existing threads, from your Mac, with Full Disk Access. We break down exactly what it does in Can you use ChatGPT in iMessage?. OpenAI's always-on agent, Dots, launched inside ChatGPT on 29 September 2026 for Pro and Business Premium subscribers, and texting it is still a limited US beta; see ChatGPT Dots alternatives.

Separately, small bridge services still relay a phone number to a chat model: text a number, get model answers back. They're the quickest way to try AI by text, but most can't touch your calendar, inbox or tools, so nothing actually gets done.

Hark Pro: app only

Hark Pro, from Brett Adcock's AI lab Hark, launched on 6 October 2026 as a free iOS, Android and web app, with $20 and $100 monthly tiers for more usage. It runs errands through its own browser agent and suggests tasks on a home screen. You use it in its app. As of October 2026 there's no number to text it on, and it doesn't place phone calls. If you came here weighing it up, see Hark Pro alternatives and Arlo vs Hark Pro.

How to choose

One question does most of the work: is the job personal or professional? For life admin, try Pally, Poke or Martin; if you're in the US or Canada and live in WhatsApp, Muse is worth a look. An executive who wants one proactive assistant should look at Catch. A Slack-first team buying per seat should look at Lindy. If the work touches your tools, your customers and your phone lines, and you want approvals and a record of what happened, that's Arlo. And if you only want help with the messages already on your Mac, ChatGPT's plugin does that. Details reflect each product's public site as of September 2026, and as of October 2026 for Pally, Instinct, Muse and Hark Pro; check them for the current state.

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, SMS or WhatsApp thread, places phone calls, asks first on money or anything unclear, and keeps an audit trail. For personal life admin, Pally, Poke and Martin are the strongest picks.

Can I text an AI assistant without installing an app? Yes. Texting-first assistants like Arlo, Pally and Poke give you a number you text like a person, from the Messages app or WhatsApp. There's no download and no new interface to learn.

Is there an AI assistant I can text on WhatsApp? Yes. Arlo, Martin and Catch all work over WhatsApp, Instinct does for people with an invite, Meta's Muse does in the US and Canada, and Poke does in some markets; Pally reads your WhatsApp inbox but you chat with it elsewhere. ChatGPT is no longer available on WhatsApp in the US; 1-800-ChatGPT stopped working there on 15 January 2026, and is available only in the European Economic Area and Brazil (what happened).

Do any texting AI assistants also make phone calls? Yes. Arlo, Pally, Martin and Catch all place calls; Instinct and Muse call businesses in early access or beta. Arlo places calls for work (confirming appointments, chasing vendors, answering questions) and keeps the transcript, so you can ask how it went.

Can I text ChatGPT in iMessage? Not from your phone. OpenAI's Messages plugin runs in the ChatGPT desktop app on Apple silicon Macs and works on your existing conversations; it isn't a contact you can text.

Are AI texting assistants safe to connect to email and calendar? Look for explicit governance: scoped access, a check with you before anything unclear or costly, and an audit trail. Arlo has all three, and shows you its own drafts before they go to someone you know; alfred_ and Pally also ask before sending, so check each product's security page for the rest.
