HeroKit vs Instinct: the Instinct AI alternative you can use today

Instinct is the AI assistant Silicon Valley spent the autumn talking about: you text it, it books, buys and replies for you. It is also invite-only, free for now with its business model still open, and it has drawn questions about privacy and reliability. HeroKit does the same everyday work from WhatsApp and Telegram, is open to anyone today, and is built so that your hero, your data and your phone number belong to you.

This page compares the two on the things people search for most: privacy, safety, WhatsApp bans, invites, price, groups and personalization. Every statement about Instinct comes from the sources listed at the end, with dates. Instinct is a trademark of its owner and is named here only to compare the two products.

What is Instinct AI?

Instinct is a personal AI assistant operated by Spear Street Technology, a San Francisco company. Its founder, Noah Shinn, is a former research scientist at Sierra. Instinct’s homepage describes it as “a personal assistant that understands what you’re working on”, with “no new interfaces”: you text or call it, and it can use a phone and a computer the way you do.

Users connect it to WhatsApp, iMessage, text messages and their email, and it handles tasks such as replies, calendars, travel, home services, shopping and bookings. Reporters have used it to book a cabin, order groceries, cancel forgotten subscriptions and deal with customer service.

Instinct raised money fast. Quartz reported on August 27, 2026 that it was raising a $250 million Series B at a $2.5 billion valuation, bringing its total funding to $350 million, and that the product was in private beta and not available to the public.

HeroKit vs Instinct at a glance

Privacy: is Instinct AI safe?

Privacy is the first thing people ask about an assistant that reads their email, so this is where the two products differ most.

How HeroKit is built. Every HeroKit customer gets their own dedicated server, their own hero and their own phone number, set up the moment they pay. Your hero’s conversations, files, memory and the access to your connected accounts live on that private machine. Other customers’ heroes run on their own machines, and no customer can reach another customer’s hero or data. HeroKit’s central account system keeps only what it needs to run your subscription: your email, your plan and payment status, your verified phone number, and your hero’s name and photo.

To write replies, your hero uses the AI processing service named in our privacy policy, under a contract that limits it to running HeroKit for you. We do not sell your data and we do not use it for advertising. Passwords and keys your hero uses are kept in an encrypted vault, and you can disconnect any app, export your data or delete your account from your dashboard.

What has been reported about Instinct. Instinct’s terms and privacy policy were revised on August 26, 2026. According to a summary of those documents by AI Wiki:

• Instinct may access, copy, collect and index data from the services you connect, and act through them.
• It may use your inputs and outputs to improve its products, including training models, unless you opt out. The opt-out applies going forward.
• Disconnecting a service does not by itself delete data already indexed. Deletion is a separate request.
• The terms appoint the service as your agent for agreements and transactions made on your behalf.

TechCrunch reported on August 24, 2026 that early testers found Instinct still summarizing email after access was removed, could not at first delete indexed Gmail records, and in one case saw an email sent without confirmation. One tester said the team later added a control to delete external data. Instinct told The Wall Street Journal it was taking the concerns seriously.

On the business model, Quartz reported, citing Forbes, that the app is free for now and that the models under consideration include a paid tier or an advertising approach drawing on the app’s visibility into users’ communications and financial activity. No decision had been announced as of November 5, 2026.

Reliability: Instinct WhatsApp bans and outages

Account bans. NDTV Profit reported that several WhatsApp users complained Instinct stopped replying, and that one user posted on October 31, 2026 that his WhatsApp account was banned right after he signed up, with no way to appeal. NDTV Profit added that WhatsApp’s terms restrict unauthorized automated use of its service, but that nothing so far showed those rules were applied to Instinct’s users.

Outages. On November 2, 2026, Instinct’s founder posted that for part of the morning it could not reply to WhatsApp users because a configuration issue had interrupted payments to one of its service providers, and that the issue was fixed. A tester also noted outages on September 22 and 23.

How HeroKit avoids putting your account at risk. Your hero has its own dedicated phone number on WhatsApp and Telegram. You message your hero from your personal account, the same way you message a colleague, and your personal account is never the one HeroKit connects or automates. If something ever happens to your hero’s number, HeroKit replaces it for you, and your own WhatsApp is untouched.

Personalization: your hero, your name, your face

This is what HeroKit is known for. You create a hero and decide who they are: the name people see, the profile photo, the about line and the personality, from short and formal to warm and chatty. You can pick one of our heroes, like Leo or Sveta, or upload your own picture. One edit updates WhatsApp and Telegram together, so it is the same person on both apps, in your private chats and in your groups.

Instinct’s public materials describe an assistant you text, but we found no documentation of choosing its name, photo or persona.

Availability: Instinct invite code and waitlist

Instinct was introduced on August 26, 2026 as a private beta. Access comes through its waitlist or an invitation from an existing member, and testers reported a limited number of invites per member. Guides warn that invite codes sold by strangers are a scam risk.

HeroKit has no waitlist and no invite codes. You enter your name and email, pay for your first month, and your dedicated server, your hero and their phone number are set up for you. You check your phone, create your hero in your dashboard and start messaging.

Pricing: is Instinct AI free?

Instinct is free during its beta. Its terms leave room for fees later, and its business model was still under consideration in the latest reporting.

HeroKit is one plan, the Hero plan, at $99 a month with every feature included: your own server, your hero’s phone number, WhatsApp and Telegram, groups, voice notes, Smart Tutor, reports and the live dashboard. It is monthly, you can cancel any time, and there are no ads.

Groups: can Instinct work in WhatsApp groups?

HeroKit heroes work inside WhatsApp and Telegram groups. Add your hero to a team, family or class group; tag your hero with an @mention and they answer in the group, pull numbers, track requests as tasks and tag the right people. Private items stay private.

We found no documentation of Instinct working inside group chats as of November 5, 2026, so we list it as not documented rather than not possible.

Everything else HeroKit does

• Telegram as well as WhatsApp, with the same hero and number.
• Voice notes in and out, in any language, so you can talk from the car and hear the answer back.
• Smart Tutor: a private tutor for languages, math, exam prep or coding, with voice-note lessons, quizzes, homework checks and a weekly progress summary.
• Reports and business intelligence from your dashboards and databases, by brand, campaign or client, on demand or on a schedule.
• Routines: a morning brief, daily digests, weekly reports and “tell me when X happens” watches that run while you sleep.
• A live dashboard that shows what your hero is doing, with a weekly usage report.
• A referral program with credit for every friend who joins.
• Multilingual from the first message: write or speak in your language and your hero answers in it.

Switching from Instinct, or can’t get an invite?

You do not need to give anything up to try HeroKit. Your hero has its own number, so it runs alongside any other assistant while you compare. Connect the same Gmail and calendar, forward your hero the chats that matter, and add them to one busy group for a week. If you are on the Instinct waitlist, you can start with HeroKit today and decide later.

Create your hero or see how HeroKit works.

Instinct AI review: the bottom line

Instinct has impressed many early users with what it can get done from a text message, and it is backed by some of the best-known investors in Silicon Valley. It is also a young, free, invite-only beta whose terms, business model and reliability are still settling.

HeroKit is for people who want that kind of help now, on WhatsApp and Telegram, with a clear monthly price, their own private server, an assistant with its own number and a personality they designed themselves.
