Leverage AI to reinvent how home buyers find the house of their dreams.

Zefir wanted to open a new vertical: a platform for home buyers. I designed its AI search in natural language, the first step toward an assistant that covers buying a home end to end.

Buyer search

The problem

We had to stand out from the traditional portals. In interviews, buyers described problems that came up across the market. They wanted to see every home that could fit, for fear of missing one, yet they were tired of seeing homes that weren't relevant to them.

The bet

“Let AI go through all the listings for buyers, and say why each result fits.”

What I did

01

Searching in your own words

Buyers describe what they want. The assistant separates fixed from soft criteria and asks qualifying questions. Tags on each home card, drawn from its description, say why it fits. Photos are reordered when it helps.
