Our AI system cross-checks multiple data sources to give you a complete view of the property.

We detect easements, tax encumbrances, preventive annotations, and other rights affecting the property.
📐 Real vs advertised surface
We cross-check listing surface area with Registry and Cadastre data to detect discrepancies.
Cadastre Verification
We compare listing data with official Cadastre records: real area, cadastral value, and build year.
AI Visual Analysis
Our AI analyzes photos to detect humidity, cracks, old installations, and estimate renovation costs.
Area Context
