Instinct is a personal AI agent that works through texts and phone calls. No new app to learn. It handles everyday tasks the way a human assistant would: ordering groceries, booking trains, sending flowers, finding a court for the weekend. The company launched in private beta in February 2026. Shinn says it has spent $0 on marketing.
That is worth pausing on. Zero marketing spend. Growth ran on invites, five per user. By the time the company raised $1 billion in a September Series C, users were selling invitations on eBay.
The product is made by Spear Street Technology, Inc., operating as Instinct. The founder is Noah Shinn, 23, a former research scientist at Sierra who left to start the company. Sierra was co-founded by Bret Taylor, OpenAI’s board chair. Shinn left Northeastern University in 2023 to join Sierra as one of its first employees.
What Instinct does
The homepage puts it plainly: “Instinct is a personal assistant that understands what you’re working on and what’s important to you.” The differentiator is what it doesn’t require. “There are no new interfaces,” the homepage says. You text it or call it. It carries out tasks using its own computer and phone, the way a human assistant would.
The task list is real-world. Book a train home. Order groceries. Send flowers. Find a court for the weekend. Those are the examples on the homepage, and they reflect where the volume actually is: travel represents roughly half of Instinct’s nearly $1 billion in annualized transaction volume.
Three features extend what you’d expect from a simple concierge bot.
Concierge handles voice calls on your behalf for appointments and reservations. It launched in early access in September 2026.
Trusted Person network lets your Instinct agent coordinate with the agents of your contacts. If you’re trying to organize plans that involve other people, the agents coordinate with each other.
Files lets Instinct build private or public interactive pages to compare options or lay out a plan. Rather than just responding in a text thread, it can structure an output you can share or return to.
The interface
The core interaction model is a text thread and a phone call option. This is not a limitation the company is working around. It’s the design.
The implication is that there is no learning curve. You don’t need to find a feature buried in a menu. You say what you want. Instinct figures out the steps.
The product runs on web, Mac OS, and mobile apps in addition to SMS. Google Workspace integrations are available: Calendar, Gmail, Drive, Docs, Sheets, Slides, and Tasks. Microsoft 365 is not listed.
How you get access
Instinct is invite-only. Each user gets five invites to share. The company has not announced a public launch date.
If you don’t know someone with an invite, the waitlist at instinct.com is the path in. The terms of service mention “a welcome text when your spot becomes available, waitlist updates” (Source). It gives no date.
Demand has outrun supply. By September 2026, invites were showing up on eBay.
Pricing
Instinct is free. There is no pricing page. There is no announced pricing model.
For now: free to use if you can get in.
Shop Pay
As of Shopify’s Fall ‘26 Edition, announced October 28, 2026, Instinct supports Shop Pay. The scope is wider than you might expect. Shopify says shoppers can buy from any brand on or off Shopify through Claude Duet, Grok Bot, and Instinct.
The payment flow is built around keeping your card out of the agent’s hands. By default, Instinct prepares a checkout for your review and you approve it before anything is charged. You can optionally enable auto-pay with a budget cap.
At stores without Shop Pay, Shop can use a limited-use payment credential, such as a token or one-time virtual card.
Personal Agent Protocol
On October 6, 2026, Sierra and Meta announced the Personal Agent Protocol, an open standard for how personal agents interact with businesses. Instinct is a named industry partner alongside Genesys, Rocket, Shopify, Stripe, and Walmart.
The protocol addresses a practical friction: most personal agents today use websites and apps the way people do, loading pages and clicking through forms. The standard is designed to give businesses a way to serve agents directly. It’s open for anyone to implement.
For Instinct users, I read this as a signal about where the product sits in the broader category.
Privacy
This is the section that needs to be read carefully.
Instinct’s privacy policy and terms of service were both last revised on August 26, 2026. That revision followed a backlash from early testers. According to TechCrunch, the original terms granted the company a “perpetual and irrevocable” license to user-provided material. The company revised the terms after the criticism.
What the current policy says:
Training. AI model training on your data is on by default. You can opt out at app.instinct.com/settings. If data has been flagged for safety review, it may still be used for training even after you opt out.
Google Workspace. The policy explicitly carves out Google Workspace data: “We do not use information received from Google Workspace APIs to evaluate, fine-tune, train, or improve AI models.” There is no equivalent carve-out for audio and voice data or precise location, which the policy says it may collect if you enable or share them.
Data selling. The policy states: “We do not sell your information or disclose your information to registered data brokers or third parties who resell your information to others.”
Risk disclosure. The policy acknowledges that autonomous agent features “may present additional privacy and security considerations because these features can perform tasks or take actions independently on your behalf.” It names the risks: unintended payments or communications to outside parties, incorrect or incomplete outputs, and third parties who may include misleading instructions meant to influence the agent.
Children. The service is not intended for children.
The fact that the company revised its terms once already matters for evaluating the current policy. The current language is better than the original. It is still opt-out training, not opt-in.
Who Instinct is for
The clearest profile: someone who wants to offload practical logistics and doesn’t want another app to manage. Book dinner, order the groceries for the week, follow up on a purchase, coordinate a weekend plan with friends whose agents can talk to yours. That’s the pitch.
The other profile: someone who makes enough phone calls that Concierge would actually save time. Appointment-heavy schedules, businesses that don’t take online bookings, any situation where “I’ll have my assistant call” is a real thing to say.
The limiting factor is access. You need an invite or a spot on the waitlist. The product is worth requesting if the task profile above matches your life. If you need something today, most of the alternatives below are live.
Alternatives
The always-on personal agent category is filling in quickly. These are the options TechSifted has covered.
ChatGPT Dots is OpenAI’s always-on agent, running on GPT-6 Astra with its own cloud computer. It’s included in Pro (from $100/month) and Business Premium plans. The access gate is high but the product is live.
Claude Duet is Anthropic’s proactive agent, running on Opus 5.5. It’s on a waitlist in the US for Claude Pro ($17/month billed annually, $20 monthly), Max ($100/month), and Ultra subscribers. It has 6,000+ connectors and asks before sending messages or making payments.
Grok Bot is SpaceX Super Intelligence’s persistent agent inside The X Subscription, starting at $30/month (Source). It bundles Grok, Grok Bot, Cursor, and X Premium into one plan.
Meta’s Muse, covered in our September overview, is a competing personal agent you message in the Muse app or directly in WhatsApp. It has a free version with a usage limit, and it climbed to No. 1 on the U.S. App Store after launch.
The Instinct difference: it costs nothing, has no paid plan, and works through texts and calls rather than inside another platform.
The honest read
Instinct earns its reputation. Free access, a text-and-call interface with nothing new to learn, transaction volume approaching $1 billion a year, and a Shop Pay integration that works at any store.
The case against it is specific. Training is opt-out, the privacy terms had to be rewritten once, and the business model is undeclared. If you have personal data you would not want used to train a model, read the privacy policy before connecting your accounts. The opt-out is there, but training stays on until you use it.
I expect the access problem to be temporary. The company is not a closed research lab. It is building a consumer product that ships Shop Pay through Shopify, and is a named partner in Sierra and Meta’s Personal Agent Protocol. The waitlist looks to me like a launch constraint, not an endpoint.
If you have an invite: set it up. The task list is practical, the interface is the simplest in the category, and it’s free. If you’re waiting: Dots, Grok Bot, and Muse are available now, though Duet has its own waitlist and only Muse has a free version.
