RealtyRadar: Real Estate Listing Checker

Buying or renting in a fast-moving marketplace is a race against bad information. Listings on Avito, Cian, and Domclick often stay online for months, get re-posted to look fresh, or appear in several versions across accounts. RealtyRadar was built to compress that noise into a few signals you can read at a glance while you browse, instead of leaving you to open a dozen tabs and guess.

The extension works as an overlay on top of the portals you already use. It reconstructs the first-publication date of an ad from historical listing data, cross-checks the description against other listings to estimate originality, and sends the ad text through ChatGPT to assess whether the language reads like a private owner or a professional agent. The result is a compact verdict you can weigh alongside photos, price, and location.

It is installed from the Chrome Web Store, runs in Russian, and is offered at no cost by an independent developer. Because it depends on third-party data and an external model call, treat its output as a shortcut for your own due diligence rather than a guarantee: verify documents, ownership, and payment terms through official channels before committing.
