Built for how people search now.
Most listing sites were designed when people typed addresses into Google. Trellistate is designed for what’s happening today — people asking AI assistants for property recommendations.
How a Trellistate listing actually reaches an AI buyer
Walking through what happens after you click Publish.
- 1
You post a listing
Describe your property, upload photos, set the price. About five minutes. The same as anywhere else.
- 2
Trellistate makes it AI-readable automatically
Behind the scenes, your listing is attached to structured data that AI assistants can understand. You don’t do anything extra — it happens whether you know about it or not.
- 3
An AI buyer-agent finds your listing
When someone asks Claude, ChatGPT, or another AI assistant “find me 3-bedroom homes in Austin under $400k,” your listing can show up in the answer — with a link back to your page.
- 4
The agent or its user contacts you
Inquiries arrive in your dashboard and in your email inbox. You see exactly who reached out, including whether it was a person or an AI agent acting on someone’s behalf.
- 5
You stay in control
You decide whether to respond. Trellistate never represents you, never negotiates on your behalf, and never takes a commission. You can pause or delete the listing any time.
What “AI-readable” actually means
Three things happen on every listing — explained without jargon.
Every listing is a clean data sheet
When an AI assistant looks at one of your listings, it doesn't see a jumble of HTML. It sees a labeled record — price, address, beds, baths, photos. That's why it can answer questions about your property accurately.
AI tools can plug straight in
Trellistate publishes a Model Context Protocol server. AI tools like Claude, ChatGPT, and Cursor can connect to it the same way they connect to a calculator or calendar. One click for the AI; nothing extra for you.
A public rulebook AI agents have to follow
We publish a file called agents.txt that tells AI bots how they're allowed to use listings — rate limits, attribution requirements, no spam. Bots that respect the rules get access; bots that don't get blocked.
Why this matters — by who you are
Property owners
Your listing reaches AI buyer-agents that are increasingly how people shop. You're early, ahead of MLS holdouts and walled-garden portals.
Real estate professionals
A free public layer where you can list properties without an MLS membership — for FSBO clients, off-market deals, builder inventory, or non-MLS commercial.
Buyers and renters
Ask any AI assistant about properties on Trellistate. Get real, structured answers — not just a list of links to click through.
AI tool builders
A public, ethical, well-documented data source. No scraping required. Attribute back to the listing and your users get real value with full provenance.
How we keep AI agents accountable
Every AI agent that interacts with Trellistate has to follow rules we set. You stay in control.
- ✓
Registered identity
Agents create an account with their developer's email and a website before they can write anything. We log every action they take.
- ✓
Rate limits
We cap how often any one agent can query the site, so a runaway bot can't hammer your listing.
- ✓
Attribution required
When an agent shows your listing in its results, it has to link back to your listing's page. You get the visit.
- ✓
No spam inquiries
Inquiries pass through the same spam protection (Cloudflare Turnstile) as human signups. Suspicious bots get blocked.
- ✓
You can hide your exact address
Check that box when posting and AI agents — and humans — get only your city, state, and approximate area. Your full address stays private.
- ✓
You see who reached out
Inquiries from people and inquiries from AI agents appear in separate sections of your dashboard. You always know which channel drove the lead.
Try it yourself in 30 seconds
Copy this prompt and paste it into Claude or ChatGPT. The AI will use the tools we built and answer with real Trellistate data, with links back to listings.
Using the Trellistate MCP server at https://trellistate.com/api/mcp, what are the three most expensive commercial properties for sale right now? Link to each one.
What you’ll see: the AI assistant reaching out to Trellistate, fetching the current top-priced commercial listings, and presenting them with prices, cities, and direct links back to each listing’s page on this site.
Why this matters: this is the same experience a real buyer is going to have when they ask their AI assistant for property recommendations — and your listing can be in that answer.
Plain-English FAQ
- Is my data being used to train AI models?
No. We don’t sell or license listing data to AI training companies. Listings are public so anyone — human or AI — can read them, but you can take a listing down at any time and we don’t bundle data into training datasets.
- Will robots flood me with fake inquiries?
No. Every inquiry is rate-limited and traceable to a registered agent. If one misbehaves we can suspend them, and you can see exactly which agent reached out from your dashboard.
- Do I need any technical skills to benefit from this?
No. You post a listing the same way you would on any listing site. The AI-readability is automatic — you don’t configure anything.
- What does it cost?
Free to post. Free to search. Free for AI developers to access the read endpoints. One day we may add optional paid tiers — featured listings, broker tools, higher API quotas — but the public listing layer stays free.
- Is this a Multiple Listing Service (MLS)?
No, and we don’t claim to be one. Trellistate is a separate open layer for listings that aren’t on the MLS — off-market deals, FSBO, builder inventory, non-MLS commercial — and also welcomes listings that are. We’re not affiliated with any MLS.
- What's the catch?
None today. We’re early. The platform is free so we can build the network. When we add paid features later they’ll be additive — the core "post your listing for free" promise doesn’t change. Read the Poster Agreement for the full terms.
Ready to put your property where AI can find it?
Free to post. Listings are public and AI-readable the moment they go live.
