AddressImmo is a browser extension designed to help users identify candidate addresses for real estate listings on platforms such as Leboncoin, SeLoger, and Bienici. By analyzing public information from the listing page—including surface area, energy performance (DPE), and postal code—the extension cross-references these details with official French public registers like ADEME and IGN. Users are presented with up to five possible addresses, each ranked by a confidence score, directly within the listing page via a "Trouver l'adresse" button.
The extension operates entirely on the user's device, ensuring that no listing data is sent to AddressImmo's servers. Instead, it accesses government APIs (ADEME, IGN, BAN) directly, and includes a feature that detects inconsistencies between the listing's stated surface or DPE and the official ADEME registry, alerting users before they proceed with an offer. 50+), Arc, and Opera (version 100+)—through the Chrome Web Store or respective extension stores.

The extension does not support Safari or mobile browsers due to platform limitations, but a manual search form is available on the AddressImmo website for mobile users, providing similar results by entering the required property details.
