What Is REX? The Real Estate AI Assistant From Blok, Explained
REX is a name more than one real estate company has used, which is exactly why the question deserves a precise answer. This post explains what REX from Blok is, what it does, who it is built for, what it costs, and how it differs from both a general AI chatbot and the other companies that share the name.
The short answer
REX is an AI workspace built by Blok for real estate agents, teams, and brokerages. It handles sales and negotiation coaching, marketing content, client communication, real estate questions, and deal workflows in one place, and it can connect to a live MLS feed for ranked comparable sales and client-ready CMA reports. Individual plans start at $29 per month at the current launch price, with a 30-day free trial. Team and brokerage plans are priced by seat.
REX from Blok is not Rex Software, the Australian real estate CRM, and it is not REX Real Estate, the discount brokerage that wound down in 2022. More on that below.
What REX does
REX is organized around the work that fills an agent’s week, not around a blank prompt box. There are five core jobs, plus an optional MLS connection.
1. Sales and negotiation coaching
Live role-play, objection handling, and call-by-call coaching grounded in proven scripts. An agent can rehearse a listing presentation, a price reduction conversation, or a buyer who is hesitating at the offer stage before the real conversation happens. We cover how to set this up in using AI role-play for objections and price reductions.
2. Marketing and content
Listing descriptions, social posts, email campaigns, and farming content written in the agent’s voice. The quality of AI listing copy depends almost entirely on what the tool is given, which is the subject of why AI listing descriptions sound generic.
3. Client communication
Replies, follow-ups, and client updates drafted in seconds rather than at the end of a long day, in the agent’s voice rather than a template’s.
4. Real estate questions
Fast, defensible answers on contracts, financing, disclosures, process, and market context. These are the questions agents would otherwise wait on a broker or a colleague to answer.
5. Workflows and playbooks
A repeatable playbook for each stage of a deal, from the buyer consultation to the closing table, so the process a top producer follows is available to every agent using it.
Plus: MLS connectivity (optional add-on)
With a live MLS connection, REX turns listing data into ranked comparable sales, market snapshots, full property history, and one-click CMA exports. This is the difference between an AI that formats a CMA and one that can source it, which we explain in can ChatGPT do a CMA. MLS connectivity is live today for Realtracs in Tennessee, with other MLSs on a waitlist.
How REX differs from ChatGPT
Most agents who use AI started with a general chatbot. In the National Association of Realtors 2025 Technology Survey, published in September 2025, ChatGPT was the most used AI tool among Realtors at 58%, followed by Gemini at 20% and Copilot at 15%. General tools are capable. The difference is how much of the business an agent has to explain before the tool becomes useful, and what data it can reach.
| Question | General AI chatbot | REX |
|---|---|---|
| Does it know real estate work by default? | Only what the agent explains in each prompt | Built around agent workflows from day one |
| Where do comps come from? | Pasted data or public sources that lag the MLS | A licensed live MLS feed, where connected |
| Does output sound like the agent? | Generic unless heavily prompted | Written in the agent’s voice |
| Can a team share playbooks? | Not as a managed capability | Team knowledge base on Business and Enterprise plans |
| Can a brokerage govern it? | Limited visibility into what agents share | Audit records, guardrails, and escalation rules on Enterprise |

Who REX is built for
- Individual agents who want coaching, content, and client communication handled in one workspace instead of across several subscriptions.
- Teams that want shared playbooks, consistent client-facing output, and one bill.
- Brokerages that want to give every agent the same level of support without hiring at the same rate as they recruit, and to govern how AI is used across the roster. That case is covered in how brokerages can give every agent an AI assistant.
REX plans and pricing
| Plan | Who it is for | What it includes |
|---|---|---|
| Individual | Single agents | $29 per month launch price. Sales and negotiation coaching, marketing and content, client communications, real estate Q&A. 30-day free trial. |
| Business | Teams | Everything in Individual, three seats included and $49 per additional seat, a team knowledge base, white-label exports, and centralized billing. |
| Enterprise | Brokerages and high-volume teams | Everything in Business, seats priced in contract, single sign-on and advanced administration, priority support, and custom integrations. |
Two add-ons are available. MLS Connectivity can be added from inside the app on any plan. Founder Voice Training, which calibrates REX to how a team leader or broker-owner actually coaches and negotiates, is available on Business and Enterprise. Current pricing is always on the REX page, and what drives per-seat pricing in this category is explained in real estate AI pricing explained.
REX from Blok is not Rex Software or REX Real Estate
At least three real estate companies have used the REX name. If you are researching REX, it helps to know which one you are reading about.
- REX from Blok is the AI assistant described in this post, built for real estate agents, teams, and brokerages in the United States. It is available at blok.co/rex.
- Rex Software is a separate company based in Australia that makes a real estate CRM and property management software used by agencies in Australia, New Zealand, and the United Kingdom.
- REX Real Estate, sometimes called REX Homes, was an Austin-based discount brokerage. It closed its offices and wound down its brokerage operations in 2022.
Blok has no affiliation with either of the other two companies.
Frequently Asked Questions
What is REX in real estate?
REX is an AI workspace built by Blok for real estate agents, teams, and brokerages. It provides sales and negotiation coaching, marketing content, client communication, answers to real estate questions, and deal workflows, with an optional live MLS connection for ranked comparable sales and CMA reports.
Who makes REX?
REX is built by Blok, a real estate marketing and technology company. It is not made by Rex Software, the Australian CRM company, and it is not related to REX Real Estate, the discount brokerage that wound down in 2022.
How much does REX cost?
The Individual plan is $29 per month at the current launch price and includes a 30-day free trial. Business plans include three seats with additional seats at $49 per seat. Enterprise plans for brokerages are priced by contract. MLS Connectivity and Founder Voice Training are optional add-ons.
Does REX connect to the MLS?
Yes, as an optional add-on available on any plan. MLS connectivity is delivered through MLS Grid and requires the agent, the broker, and the MLS to approve the data license before the feed activates. It is live today for Realtracs in Tennessee, and agents in other MLSs can join a waitlist.
Is REX better than ChatGPT for real estate agents?
For real estate work, REX starts with more context. It is built around agent workflows, writes in the agent’s voice, can share playbooks across a team, and can work from licensed live MLS data. ChatGPT is a capable general assistant, but it has no direct MLS access and needs the business explained in each conversation. Many agents use both, with a general tool for general tasks and REX for real estate work.
Is there a free trial of REX?
Yes. The Individual plan includes a 30-day free trial, which is long enough to run REX against real listings, real client conversations, and a real pricing conversation before paying anything.
The takeaway
REX is a real estate AI workspace, not a general chatbot pointed at real estate and not any of the other companies that share the name. It is built for the work that fills an agent’s week, it can work from live MLS data where connected, and it scales from one agent to a full brokerage on the same platform.
