Arlo vs Instinct — two AI assistants you text that act for you

Instinct and Arlo answer the same question — what if you could text an assistant and it simply did the thing? — and both can place calls, work across your accounts, and keep going between your messages. They differ on who they're for and on how much you get to see and approve along the way. Instinct is a personal assistant for your own life. Arlo is an AI colleague built for work, where the email goes out in a company's name and somebody may need to check later what happened.

This comparison is written by Arlo. Instinct's facts below come from its own site, its terms of service (revised 26 August 2026) and dated reporting, as of September 2026, and we say where it's the better pick.

What Instinct is (as of September 2026)

• Made by Spear Street Technology, Inc. in San Francisco, founded by Noah Shinn, and backed by $350 million at a reported $2.5 billion valuation (TechCrunch).
• Channels: text, including WhatsApp, and phone calls in both directions; it can text or call you first, and each Instinct has its own email address.
• How it works: a computer in the cloud that uses the logins you give it and keeps working between messages.
• Access and price: invite-only beta with a waitlist; free during the beta with no published pricing.
• Use: built around one person; its terms license it "for your personal use only", and it has no team or admin features.

What Arlo is

Arlo is an assistant you text on iMessage, SMS or WhatsApp, use inside Slack, or hand a phone call to. It connects to Gmail, your calendar, Slack, Notion, Linear, HubSpot and 3,000+ other tools, and uses sites with no API through a secure browser session you sign into once. Anything it sends or changes waits for your approval unless you've pre-approved that kind of action, and every tool call, source and approval goes into an audit trail. It texts you first with briefs and reminders over iMessage and SMS. It's free to start and runs on monthly plans from $20 after that.

The Instinct column reflects its public site and terms as of September 2026. Both products change quickly.

Where Instinct is the better pick

• Your own errands, at no cost today. If you have an invite and the job is personal — groceries, tickets, a road trip, cancelling subscriptions — Instinct is built for exactly that, and it's free while in beta.
• Hands-off autonomy. Instinct is designed to carry a long errand on its own with minimal check-ins. If you want to hand something off and hear back when it's done, that's its whole design.
• Pace. It's among the best-funded products in the category and ships new capabilities most weeks.

Where Arlo is the better pick

• You can start now. No invite, no waitlist.
• The work involves other people. Arlo runs inside Slack as well as your texts and connects to the shared tools a company uses. Instinct is built around one person, with no team or admin features, and its terms license it "for your personal use only".
• You want to approve what it does. Arlo holds anything it sends or changes for your approval by default and keeps an audit trail you can read back. Instinct is designed to act with fewer check-ins — it asks when it needs input, but one early user reported it sending an innocuous email "without checking with me first" (TechCrunch, August 2026).
• You want a price you can plan around. Arlo publishes its pricing. Instinct doesn't have any yet.
