Instinct: a personal agent you text, by invitation
A personal AI agent from Spear Street Technology: you text it or call it, and it acts with a phone number and a computer of its own — invite-only, and not a coding agent.
Instinct is a personal AI agent from Spear Street Technology, opened as an invite-only beta in August 2026. You text it or call it; it connects to your email, messages and accounts and acts with a phone number and a computer of its own. No price is published and the press calls it free, but getting in takes an invitation or the waitlist. It trains on your data unless you opt out, and we have not run it.
What Instinct is.
Instinct is an agent you never open. There is no new interface to learn, in its maker's words: you send it a text or call it, and it does the errand. It connects to the services you allow — email and messaging, and, if you let it, your screen, audio and location — and its homepage lists the sort of thing it is for: following up on threads you have dropped, texting or calling you first, arranging a ride to the airport, booking a handyman. When it acts it uses a phone number and a computer of its own, TechCrunch reported on 28 September, and two recent additions widen that: a concierge that makes phone calls for you to places with no online booking, and a trusted-person network through which one member's agent arranges plans with a friend's. Members also get a web workspace at app.instinct.com and a Mac app; there is no phone app.
Instinct says it has a core model of its own, trained for the personal side of everyday life; its privacy policy also lists third-party AI model providers among those that receive your data, without naming them. The company behind it is Spear Street Technology, Inc., founded by Noah Shinn. It opened the invite-only beta in August 2026 and announced a funding round on 28 September from investors including Sequoia Capital, Benchmark and Coatue, a month after the one before. It is not a coding agent, and none of its documents mentions code.
The terms are the part to read slowly, because the agent is meant to hold the keys. The privacy policy says you may give it your passwords for other services and your card details so it can sign in and pay as you, and that it may handle health information when it books an appointment; the terms appoint it your agent for agreements it makes, binding on you as if you had made them. Training on what it sees is on until you opt out — and even then, material flagged for safety review can still be used, and models already trained may still be used. Disconnecting a service does not delete what was indexed from it; that takes a separate request. TechCrunch reported that Instinct's first privacy policy drew criticism for overreach and was rewritten; the version read here is dated 26 August 2026.
We have not run it. There is no way in without an invitation or a turn on the waitlist, and asking for either to review a product is not something this desk does. Everything here is documented evidence read on the date at the top: Instinct's homepage, its terms of service, privacy policy and SMS terms, the public code of its sign-in app, and two press reports — TechCrunch's of 28 September and Fortune's of 30 September — each named where it is used.
Nothing is published. The two rows below are doors rather than plans — an invitation, or the waitlist — and the price column carries what Instinct says about money, which is nothing beyond a clause reserving the right to charge.
| Route | Bought as | Price |
|---|---|---|
| Invitation from a member | Early access | None published |
| Waitlist | Early access | None published |
When it is the wrong tool.
Structural reasons, not complaints about output quality. Each is a property of how Instinct lets people in, how its data terms are set or how little it says about money, and none will change with the next model it ships.
People pass on Instinct for four reasons — the gate, the data defaults, a price that may arrive later, or the discovery that they wanted a coding agent — and each one leads to a different shortlist.
