Cubi Estate is an AI-native property search engine for Europe. The plugin gives ChatGPT read-only access to a continuously updated corpus of over one million active sale and rental listings across Europe — Portugal, Spain, Italy, France, Germany and more — searchable in 7 languages. Tools cover natural-language search ("2-bed apartment in Porto under €400k with a balcony"), structured filtering, full listing details with source links, and day-by-day market statistics (new listings, deactivations, price drops, per country). Every result links back to its original source listing. All tools are read-only and annotated as such; nothing mutates data, and no user accounts are required.
