LandOnEarth uses ChatGPT to power search

Also taking advantage of AI tech is home search platform LandOnEarth, which has integrated ChatGPT into its HomeMatch technology.

The search portal, which describes itself as "like a dating app, but for homes," allows buyers to enter information about their needs and wants and then matches properties to the buyer's profile. The integration of ChatGPT into the company's proprietary tech "supercharges the advanced AI algorithms to analyze these data points against the full MLS inventory of homes," according to a news release.

The free search tool analyzes for-sale data as well as information on local features — such as restaurants, walking trails and demographics — to find properties that fit a buyer's profile, and then provides a match score for each home.

"At LandOnEarth, we are on the pulse of technology trends, and very much involved in leading the transitional shift happening with AI in proptech. By combining our innovative HomeMatch Technology with ChatGPT's powerful AI capabilities we can now provide an even more accurate and efficient home match experience for our agents and home buyers changing the antiquated home search experience for good," said Mario Corona, CEO of LandOnEarth.
