Your listings, found by ChatGPT, Claude and Perplexity — on your terms
Buyers are starting their property search inside AI assistants. CUBI puts your inventory in those answers — with attribution and a link back — and gives your brokers the same search power in the Cubi web app.
API access is available on request and depends on approval and integration scope.
Semantic search
Match listings to buyer intent, not just filters.
API ingestion
Connect your CRM inventory to the property index.
Instant reports
Generate property insights and comparisons in chat.
Listing → agent
Buyers reach your agents with listing context attached.
Buyers already ask AI assistants. Your listings can be the answer.
Our connector is published in Anthropic's official Claude directory and is queried by ChatGPT and Perplexity. When a buyer asks for exactly what you are selling, your listing comes back — with a direct link to the source.
- Published in Anthropic's official Claude connector directory
- Queried live by ChatGPT and Perplexity
- Every result cites and links back to the original listing
ChatGPT answers via the Cubi connector where it's installed; otherwise it falls back to its own web search.
What a licence adds
- Your feed becomes the source of record — exact prices, no scrape lag, delisted properties disappear the moment you delist them
- Attribution and a link to your site on every result — the inquiry comes to you, not to a portal
- Buyer inquiries routed to your team through Cubi Connect — by email or webhook
- Monthly analytics: queries matched, results served, inquiries routed
- Correction and withdrawal rights, opt-out at any time
Your first 3 qualified buyer leads are free — lead routing live from day one. No card, no commitment; a paid plan starts from the fourth lead.
No paid placement — ever
Ranking is determined by relevance to the query only, a commitment published in our directory listing. A licence buys accuracy and leads, not prominence.
Information for agents and agencies whose listings we index (GDPR Art. 14)
Search the whole index from inside your AI assistant
Cubi publishes a free, read-only connector. Add it once, then ask for property in plain language — your assistant answers from the live index of verified listings instead of piecing together old portal pages. It returns no agent or agency contact details.
1 — Add the connector
Settings → Security and login → turn on Developer mode, then add this URL at chatgpt.com/plugins with the + button.
https://mcp.cubi.estate/mcp2 — Then just ask
Find 3-bedroom apartments for sale in Lisbon under €500,000 with a balcony. Give me the price, the size and the listing link for each — using Cubi Estate.
Opens ChatGPT with the prompt typed in — you press send. Adding the URL needs Developer mode, a developer feature on paid plans (Plus, Pro, Business, Enterprise, Edu) and web only.
1 — Add the connector
Customize → Connectors → Add custom connector, then paste this URL.
https://mcp.cubi.estate/mcp2 — Then just ask
Find villas with a private pool near Málaga under €900,000, then compare the best three on price per square metre — using Cubi Estate.
Opens Claude with the prompt typed in — you press send. Works on the free plan too, which allows one custom connector.
1 — Add the connector
Settings → Connectors → Custom connector → Remote, then paste this URL.
https://mcp.cubi.estate/mcp2 — Then just ask
Find 2-bedroom apartments in Milan within walking distance of a metro station under €350,000, and show the price per square metre — using Cubi Estate.
Perplexity runs the search the moment it opens. Custom connectors need a paid Perplexity plan.
Connectors are added per account — free on Claude (one connector), a paid-plan feature on ChatGPT and Perplexity. Without the Cubi connector installed, each assistant falls back to its own web search — slower, and drawn from portal pages rather than the live index.
Everything agents need to search, analyze and act faster
CUBI combines indexed listings, semantic search, instant reports, comparisons and chat-based workflows in the Cubi web app.

Semantic search + exact filters
Search by buyer intent, then narrow results by country, city, price, area, bedrooms, property type, features and amenities.
Instant property reports
Generate property insights with feature analysis, similar listings, location context and map view.
Compare properties and areas
Compare listings side by side. City and region comparison is currently in beta.
Listing → Agent chat

Not just listings. A property index.

That makes it easier to search, compare and recommend properties using natural language.

Deeper context for serious property decisions
CUBI can enrich property analysis with external context such as nearby listings, transport access, travel time to airports, beaches and schools, noise and safety context, and AI-assisted visual quality signals from property photos.
External data provides context and signals, not guarantees. Safety and noise context are area-level indicators where data is available. Photo-based quality signals are AI-assisted and should be verified independently.
