What is Instinct? The personal AI assistant you text or call

Instinct is a hosted personal assistant from Spear Street Technology that you use by texting or calling it, with no app to install. Its homepage describes it as "a personal assistant that understands what you're working on and what's important to you" and says it "can use a phone and computer in the same way that you do", which is the whole proposition: you send a message, it goes and does the errand. Before you connect anything to it, read its terms, because they appoint the service as your agent to enter into agreements and transactions on your behalf, and they let the company train AI models on what you give it unless you opt out.

One note on the name before anything else. Instinct is an ordinary English word, so most search results for it are about something other than this product. The company behind this one is Spear Street Technology, its founder is Noah Shinn, and its site is instinct.com.

#What is Instinct, and who makes it?

Instinct is a consumer assistant rather than a developer tool. The product is offered by Spear Street Technology, which TechCrunch reported on 26 August 2026 is "helmed by a 23-year-old", founder Noah Shinn.

The pitch on instinct.com is deliberately minimal: "The interface is simple: there are no new interfaces." There is no application to download and no dashboard you are expected to live in. You text or call the assistant, and the examples the homepage gives are ordinary household errands: ordering recipe ingredients, booking a train home for the weekend, ordering groceries, sending flowers to a friend, and finding a court for the weekend.

That framing matters for what follows. A tool with no interface of its own has to reach into the accounts and devices you already use, and that is exactly what its terms and privacy policy describe.

#How do you reach it, and what can it do?

Text and phone calls are the core. Everything else has arrived since August 2026 and each piece has its own rollout state, which is worth checking before you plan around a feature.

Capability	What it does	Status as reported	Source and date
Text and phone calls	The two channels you use to reach the assistant	The core product on instinct.com	instinct.com, read 26 Oct 2026
Email address at mail.instinct.com	The agent gets its own address, which it uses to create and manage accounts, contact businesses and follow up on tasks	TechCrunch reported Instinct was "giving everyone Instinct email addresses", with some reserved for its earliest users	TechCrunch, 9 Sept 2026
Outbound phone calls, and Instinct Concierge	Shinn announced "Your Instinct can now handle phone calls"; Concierge is "a white glove service meant to handle high-touch cases, such as making phone calls, high-end service booking, and more"	"rolling out in early access to some users, with plans to expand to all users in time"	TechCrunch, 17 Sept 2026
Assistant-to-assistant contact	Your assistant can contact other people's assistants for some tasks, once you are added to a trusted network	Reported as live for users in the trusted network	TechCrunch, 17 Sept 2026
Group chats	The agent joins a group thread: "A new Instinct joins and works for the whole group", and it works even if your friends have not joined Instinct	Rolling out to early access users first, expanding to all users "soon"; you can ask your agent to add you to the waitlist	TechCrunch, 5 Oct 2026

The group chat design is the one place the company has described a permission boundary in public. TechCrunch reported on 5 October 2026 that the group's agent is siloed from members' personal accounts, which it cannot access, that a personal agent must ask permission before connecting to the group agent, and that "the personal agent will always ask the user's permission before sharing information or taking any action". Users choose which groups to trust and can revoke that trust.

#Can you sign up, or do you need an invitation?

The vendor does not answer this on the pages we read. As of 26 October 2026 instinct.com carries a "Try Instinct" link to a login page, a "Log in" link and an "Invite a friend" link, and it states no eligibility rules, no waitlist and no invitation process. The pages we checked for that are the homepage, the terms and the privacy policy.

What there is comes from the press, and it is consistent across two outlets without being current:

• TechCrunch reported on 26 August 2026 that Instinct "is currently in private beta".
• PYMNTS reported on 16 September 2026 that a post by Noah Shinn described it as "an invite-only beta program", and called it "the invitation-only agent".
• TechCrunch reported on 5 October 2026 that users can ask their Instinct agent to add them to the waitlist for group chats, which is a waitlist for that feature rather than for the product.

So the honest answer in late October 2026 is that the most recent reporting we could find describes a gated beta, and the company publishes nothing about how to get in. If you are not already a user, the only route the vendor's own site offers is an invitation from someone who is.

One eligibility rule is published, in the terms rather than on the homepage: "You must be 18 years of age or older to use the Services." The terms also say that "those who choose to access the Services from locations outside the United States do so at their own initiative", and that they are governed by the laws of the State of California.

#What do Instinct's terms let it do?

This is the section to read twice. The terms of service, last revised on 26 August 2026, contain a clause most consumer software does not:

You hereby appoint the Services as your agent to enter into agreements, commitments or transactions on your behalf

An assistant that books a train and orders groceries needs some version of that authority to function. It is still a broader grant than a conventional terms-of-service acceptance, and it is the clause to weigh before you connect a payment method or a bank-linked account.

TechCrunch reported on 26 August 2026 that users had raised concerns about "the overly generous permissions that the app requires", and that some were disturbed by the terms of use for their "invasive potential". That is press characterising user reaction, not a vendor statement, but the clause above is the vendor's own wording and you can read it yourself.

#What does Instinct do with your data?

The privacy policy, also last revised on 26 August 2026, is specific, and it is the document that tells you how much reach the assistant has.

On training, the default is opt-out rather than opt-in. The terms say "you agree that we may use Materials to develop, provide, maintain and improve the Services", and the privacy policy says usage data and information from the services is used "to evaluate, fine-tune, and train the AI models that power our products and technology". Three documented limits apply:

• The Vault. For materials you add to the Vault feature, the terms say "we will only use such Materials to provide the Services to you and will not use such Materials to train AI models."
• Google Workspace. The privacy policy says "we do not use information received from Google Workspace APIs to evaluate, fine-tune, train, or improve AI models", and that Workspace data is not given to third-party business partners for their own purposes.
• The opt-out. You can opt out of AI training at app.instinct.com/settings. Two caveats are in the policy itself: safety-flagged information may still be used for training, and "we may still use AI models previously trained, fine-tuned or improved on your information prior to your opting out."

On collection, the policy lists contact details, payment information and the messages you send, plus content from connected apps including messages, emails and documents. It states plainly that the assistant may access sensitive information such as payment details or login credentials. Audio and voice data are collected if you enable those features, and precise geolocation if you choose to share it. For Google Workspace it names file metadata, message metadata and calendar event details.

On sharing, the policy says "we do not sell your information" to data brokers or resellers. It does share with vendors, service providers, affiliates, professional advisors and "third-party AI model providers who help support the Services", as well as with third parties the assistant contacts on your behalf.

Two operational details are easy to miss and worth acting on. The policy sets no specific retention periods; it describes deletion instead. And disconnecting an integration does not automatically delete the data already collected from it, so revoking access is not the same as cleaning up. Deleting your account in Instinct's Workspace removes data collected from Google Workspace, and externally indexed data is deleted at app.instinct.com/workspace. Privacy questions go to privacy@instinct.com.

If you want the general version of this question rather than Instinct's, is Meta Muse safe? works through the same problem for a rival consumer agent, where the vendor publishes a documented permission model.

#How much does Instinct cost?

No published price, and two sources that pull in different directions.

The terms say both that "you may be required to pay us fees to access or use certain features of our Services" and that "the Company may, at any time, revise or change the pricing for the Services, or any portion thereof." That is the vendor's own document reserving the right to charge.

PYMNTS reported on 16 September 2026 that chief executive Noah Shinn does not want to charge users, and suggested the company could pursue other revenue such as advertising. Treat that as reported intent. It is not a price, not a commitment, and it sits beside terms that explicitly allow fees to appear and change.

We found no published pricing page, and no plan tiers we could cite from the vendor or from reputable reporting.

#What has Instinct raised, and at what valuation?

The funding is reported rather than announced on instinct.com, and the two outlets we read disagree on one number.

• The round. TechCrunch reported on 26 August 2026 that Instinct raised a $250 million Series B "co-led by Index Ventures and Benchmark", which "brings the company's total funding to $350 million". TechCrunch says the company told The Wall Street Journal about the round.
• The valuation, which conflicts. TechCrunch reported that the round "gives the startup a valuation of $2.5 billion". PYMNTS, on 16 September 2026, put the same August round at "a $2.25 billion valuation". This article follows TechCrunch's $2.5 billion as the figure closer to the round's announcement, and notes that PYMNTS reports $2.25 billion. Neither number is published by the company.
• Reported talks, not a closed round. PYMNTS reported that Spear Street was in talks to raise $1 billion at a $10 billion valuation, citing The Information, and attributed the valuation figure to an unnamed source. We treat that as a rumour: it is a report of talks, sourced anonymously, and we found nothing from the company confirming it.
• Users. PYMNTS reported that the user base had passed 100,000. It names no source for the figure, and the company publishes no user count, so it is a secondhand number.

#How does it compare with other personal agents?

Instinct sits at the hosted and gated end of the spectrum: the company runs it, access appears to be gated, and there is no developer surface. As of 26 October 2026 instinct.com publishes no developer documentation and describes no skills, plugins, MCP servers or API, so what Instinct can reach is whatever accounts and devices you connect, not what you can extend it with.

That is the opposite trade from a self-hosted agent, where you supply the machine and the keys and keep the extension points. For the side-by-side on price, where each one runs, who can sign up and whether you can write your own skills, see personal AI agents compared. Meta's Muse is the closest rival in the consumer category, and note the name collision there too: Muse the agent is not Muse Spark, Meta's model family. TechCrunch covered both Instinct and Muse adding call handling on the same day, 17 September 2026.

The platform facts we keep current for this product, including what its terms and privacy policy say at each check, live on the Instinct hub.

#What we could not confirm

We did not use Instinct. Nothing here reports behaviour we observed: the product description comes from instinct.com, the permissions and data handling from the terms and privacy policy, and everything about funding, access and feature rollouts from the dated press reports named above.

Several figures circulating about Instinct are not in this article because we could not trace them to the company or to reporting we would cite. Specifically: monthly subscription tiers in the low hundreds of dollars, a count of invitations per user, a daily growth rate, a share of tasks that are travel bookings, and named customer-service partnerships. Each appears only on aggregator sites with no primary source behind it.

We also could not confirm the current access state from the vendor. The pages we checked, the homepage, the terms and the privacy policy, say nothing about invitations, waitlists or eligibility beyond the 18-and-over rule, so the gated-beta description here rests on press reports from August and September 2026 rather than on anything the company publishes today.
