Instinct saved $550, wasted $64 — and might be a risk

Instinct saved $550, wasted $64 — and might be a risk

3 Key Points

  1. What happened

    The author gave Instinct, an invite-only AI agent reachable via iMessage and WhatsApp, access to her email and calendar. It spotted that Alaska had moved her flight 90 minutes earlier, qualifying her for a roughly $550 refund, and later flagged a phishing BBQ invite as "NOT TO OPEN."

  2. Why it matters

    An agent that can catch missed airline changes worth hundreds of dollars is useful for busy travelers, yet the author describes it as a mildly chaotic personal assistant and has decided to stick with it despite the risks.

  3. What to watch

    The author still had to forfeit money on a canceled order she'd told it to cancel only for a refund, and she warns that agents are a security nightmare — the test is whether convenience outweighs such lapses for everyday users.

WHO IT HITSBusy professionals who hand an AI agent access to email, calendar, and payments — such as frequent travelers or parents outsourcing scheduling — may gain from missed refund opportunities, but they shoulder the risk of an agent acting against explicit instructions or exposing their inbox.

Context & Analysis

Instinct's pitch is its form factor: no open text box, just iMessage, WhatsApp, and a few helpful prompts. AI researchers the author spoke with emphasize this repeatedly. Instead of the user figuring out what to ask, the agent suggests things it can do and then does them — a contrast with Claude Cowork, which the author found felt like a regular chatbot with extra tools, and with Lindy, which she deleted after it texted every morning and joined Zoom meetings without approval.

Her experience set the boundary of what these agents can handle. Restaurant reservations in Venice were a success, and so was a more complicated New York trip: she'd booked a saver fare she couldn't move, and Instinct detected a 90-minute Alaska schedule change she'd missed, qualifying her for a full refund. But the same agent canceled a delayed DoorDash order against her explicit instruction, costing her $64. The article notes other users' reports of inbox retention, a Resy ban after roughly 200 API calls per hour, and easy phishing exposure. Instinct, the company, did not respond to WIRED's requests for comment.

The wider context is a widening divide between people who use AI agents for everything and those who've never tried one. That gap, the author suggests, helps explain why tech CEOs were caught off guard by data center backlash. Whether Instinct-style agents bridge it likely hinges on whether their costs — forfeited money, unseen data retention, and Terms of Service that allow training on conversations — stay tolerable for users who, like the author, are simply too busy to keep doing everything themselves.

FAQ
How much does Instinct cost?
The article doesn't give a price. It says Instinct is invite-only, launched in private beta in February, and is reportedly in talks to raise $1 billion on top of the $350 million it's already raised, at a $10 billion valuation.
What can Instinct actually do?
It connects to your email, calendar, and messaging apps. The author had it book restaurant reservations in Venice — including WhatsApping spots — cancel a trip for a refund, rebook a one-way return, and warn her about a phishing email.
What are the risks of using Instinct?
Users reported it retained a copy of their inboxes after they tried to disconnect it. A venture capitalist said he was banned from Resy after the bot pinged its API roughly 200 times per hour, and its Terms of Service allow the company to use at least some conversations to train its AI models.
