Instinct AI for Real Estate Agents: How to Get In, What It Does, What to Watch

Instinct is a free, invite-only personal assistant you text or call. It connects to Gmail and Google Calendar, drafts replies, follows up on threads you dropped and now makes calls in early access. It names no CRM, MLS or real estate feature, and early users reported privacy and reliability problems. Here's what an agent should know.

What Instinct is

Instinct is a personal assistant from a San Francisco startup that you use by texting or calling it, like a person.

Its homepage says it "understands what you're working on and what's important to you" and connects to your email, messaging, screen, audio and location. The company behind it is Spear Street Technology, doing business as Instinct.

Its founder, Noah Shinn, was a research scientist at Sierra.

Money followed fast. Instinct raised a $250 million Series B co-led by Index Ventures and Benchmark at a $2.5 billion valuation, about $350 million in total.

The Information reported talks to raise about $1 billion more at around $10 billion, and more than 100,000 users.

How to get an invite

You need an invite from a current user or a spot off the waitlist, plus a US phone number.

  1. 01Ask someone who has it. Current users can invite others; the app shows five invites per user.
  2. 02Join the waitlist at app.instinct.com. Its terms describe a welcome text when your spot opens.
  3. 03Use a US phone number. The sign-up screen says US numbers only.
  4. 04Expect a wait. Instinct has told users it is at full capacity and responses may be slower.
  5. 05Skip invite codes sold online. You'd be paying a stranger for something current users give away.

What it can do for an agent

In Instinct's words, it handles "following up on threads you've dropped, proactively calling or texting you" and booking things like a handyman.

What it doesn't say it does

Instinct names no Follow Up Boss, kvCORE, MLS or Zillow connection, and it doesn't describe texting your clients from your own number.

Outlook and Microsoft 365 are not named in any public Instinct document we could read. Group texts are not stated.

Instinct describes a number you text or call; it doesn't describe a business line your clients can text. The only real estate stories so far are from buyers: Shinn said some users have used it to buy homes and find rentals.

One early user, quoted by TechCrunch, listed "CRM management" among his uses. That is one person's setup, not a feature Instinct lists.

What early users ran into

Early users called Instinct "like magic," and early coverage also reported a few problems an agent should weigh.

5 tips if you get in

Treat week one as a trial with your personal accounts, not your business.

  1. 01Turn off training at app.instinct.com/settings. It is on by default, and the opt-out only covers data from then on.
  2. 02Start with a personal Gmail, not your brokerage inbox.
  3. 03Tell it to ask before it sends or books anything, and check that it does.
  4. 04When you leave, delete what it indexed from your apps at app.instinct.com/workspace. Disconnecting alone does not delete your data.
  5. 05Keep client financial documents and ID numbers out of it.

Where Sifta fits

Sifta is the business version of the same idea: an assistant you text, built only for real estate agents, that you can start today.

Instinct is trying to run your whole life. Sifta runs one thing, your real estate business, and any agent can start without an invite.

Sifta is an AI assistant built only for real estate agents. Here is what it does:

  • Connects to Gmail or Outlook and your calendar, and runs by text from the Messages app on your phone.
  • Drafts the reply to each portal lead in your voice, with real open times, and texts it to you to approve.
  • Tracks the deal dates it finds in your email.
  • Pulls comps on any address you text it.
  • Books showings from the group text with your client.
  • Briefs you every morning.

It does not make phone calls and it is not a CRM. Sifta Pro is $199 a month.

If Sifta doesn't catch something worth more than the price in week one, you don't pay.
