The AI assistant you can text on WhatsApp
Arlo is an AI assistant you text on WhatsApp — free to start, with no app to install. Message it like a contact and it answers, researches, drafts, schedules, and takes real actions in Gmail, your calendar, Slack, Notion and 3,000+ other tools, asking before anything is sent. It understands voice notes, photos and documents, and it can place phone calls for you.
Most AI on WhatsApp answers your question and leaves the work to you. Arlo is an AI colleague that sits in your chat list like any other contact and does the job. It reads the email thread, books the time, updates the record, and makes the call. It's the same assistant you can text in iMessage, use in Slack, or hand a phone call to, and it remembers what you told it in any of them.
What you can do from WhatsApp
- Ask anything. Research a question, compare options, and get an answer with its sources.
- Send a voice note. Talk instead of typing. Arlo transcribes it and gets on with it.
- Send a photo or a document. A receipt, a contract, a screenshot. It reads the contents. Send one file per message.
- Act in your tools. Draft the Gmail reply, move the meeting, update HubSpot or Notion, file the Linear issue.
- Get a call made. Confirm the appointment or chase the supplier, then ask how it went.
What's different on WhatsApp
WhatsApp only lets a business message you within 24 hours of your last message. So on WhatsApp, Arlo answers the conversations you start. Scheduled briefs and reminders, the ones that text you first, are an iMessage and SMS feature. Everything else works the same.
Arlo vs. other AI on WhatsApp
Meta AI is built into WhatsApp and free, and since September 2026 Meta's Muse agent works inside WhatsApp too. It connects to your email and calendar and can book and buy things for you. For personal errands, that's a strong free place to start. Arlo is built for work instead: it reaches the tools a company runs on (Slack, HubSpot, Notion, Linear and about 3,000 others), holds anything it sends or changes for your approval, keeps an audit trail of every action, and is the same assistant in iMessage, Slack and on phone calls.
Other texting assistants work over WhatsApp too, including Martin, Catch, and Poke in some markets. The best AI assistants you can text compares them, including where each one is the better pick.
Governed by default
An assistant that can act has to be safe to trust. Every connection resolves through policy before a run, anything that sends or writes waits for your approval, and every tool call, source, and approval lands in a full audit trace. On WhatsApp, Arlo only sees the messages you send it.

Questions about Arlo on WhatsApp
Is there an AI assistant I can use on WhatsApp?
Yes. Arlo works on WhatsApp: you message it like a contact and it answers, researches, drafts, schedules, and takes real actions in your email, calendar, and work tools. There is no app to install and nothing to set up beyond connecting your number.
Is ChatGPT still on WhatsApp?
Not in the US. 1-800-ChatGPT stopped working on WhatsApp in most countries on 15 January 2026, after Meta restricted general-purpose AI chatbots on its business platform. It stayed available in Brazil and returned for users in the European Economic Area in July 2026.
Can an AI on WhatsApp actually do things, not just chat?
Arlo can. It connects to Gmail, Google Calendar, Slack, Notion, Linear, HubSpot and 3,000+ other tools, so a message like "move my 3pm and tell the team" gets done rather than explained. Anything that sends or writes waits for your approval, and every action lands in an audit trail.
Does it understand voice notes, photos, and documents?
Yes. Send a voice note and Arlo transcribes it and acts on it; send a photo, a PDF, or a document and it reads the contents. Send one file per message — several attachments in a single message aren't read.
Is it free?
Arlo is free to start: a new account begins with $25 in credits (10,000), with no card and no expiry. Paid plans come in only once you've used it.
Can it text me first on WhatsApp?
Not on WhatsApp. WhatsApp only lets a business reply within 24 hours of your last message, so there Arlo answers what you send it. Scheduled briefs and reminders that text you first are an iMessage and SMS feature.
Can Arlo read my other WhatsApp chats?
No. Arlo only receives the messages you send to it. It can't see, read, or monitor your conversations with anyone else.
How is this different from Meta AI in WhatsApp?
Meta AI is built into WhatsApp and free, and Meta's Muse agent, launched in September 2026, connects to your email and calendar and can book and buy things — a strong option for personal errands. Arlo is built for work: it reaches Slack, HubSpot, Notion, Linear and 3,000+ other tools, holds anything it sends for your approval, keeps an audit trail, and is the same assistant across WhatsApp, iMessage, Slack, and phone calls.
