CoStar Group Launches Apartments.com Ai, Redefining the Future of Apartment Search

Industry-leading rental marketplace introduces a conversational AI experience that acts as a trusted rental advisor, helping renters discover, compare and evaluate apartments with unprecedented intelligence and personalization

ARLINGTON, Va.--(BUSINESS WIRE)--CoStar Group (NASDAQ: CSGP), a leading provider of online real estate marketplaces, information and analytics, today announced the launch of Apartments.com Ai, a transformative new apartment search experience that fundamentally changes how renters discover, evaluate and lease their next home.

Powered by artificial intelligence and built on Apartments.com’s unmatched depth of multifamily data, Apartments.com Ai replaces traditional filters and keyword searches with natural, real-time conversations that feel less like navigating a website and more like working with a deeply knowledgeable rental advisor.

Available to every renter on every Apartments.com visit, Apartments.com Ai understands renter preferences, answers complex questions, compares communities, surfaces relevant recommendations and guides consumers through every stage of the apartment search journey.

Earlier this year, Apartments.com introduced the multifamily industry’s first AI-powered apartment smart search experience. Insights from that launch and extensive consumer testing helped shape the development of Apartments.com AI, creating a more intelligent, personalized and intuitive renter experience.

Renters can simply describe what matters most to them - whether it’s “a quiet apartment near great restaurants and my office,” “a pet-friendly community under $2,000 a month with easy subway access,” or “a luxury apartment with a gym and outdoor space near downtown” and receive highly personalized recommendations tailored to their lifestyle and priorities.

Beyond finding apartments, Apartments.com Ai helps renters evaluate options with greater confidence. The experience can answer detailed questions about properties and neighborhoods, compare similar communities, guide renters through immersive Matterport 3D Tours and rich media experiences, and assist renters with contacting the property.

“Finding an apartment is one of the most important decisions people make, yet the search process has remained largely unchanged for years,” said Andy Florance, Founder and Chief Executive Officer of CoStar Group. “Apartments.com Ai represents a fundamental shift from searching listings to having a conversation with a trusted rental advisor. By combining artificial intelligence with the most comprehensive multifamily data in the industry, we can understand what renters are truly looking for, guide them through their options and help them find a home that fits their lifestyle with far greater speed, confidence and precision.”

Powered by Apartments.com’s industry-leading property information, neighborhood intelligence, pricing insights, professional photography, videos and Matterport 3D Tours, Apartments.com Ai delivers a richer and more informed search experience than general-purpose AI tools.

A major evolution in apartment search, Apartments.com Ai moves beyond traditional listing discovery toward intelligent, conversational guidance that reflects how people actually make renting decisions. The platform continuously learns from renter interactions, building a deeper understanding of consumer preferences and delivering increasingly relevant recommendations over time.

The launch builds on CoStar Group’s broader investment in artificial intelligence-powered real estate experiences. Earlier this year, CoStar Group introduced Homes Ai, an interactive conversational search experience that helps consumers discover homes, explore neighborhoods and evaluate properties through natural dialogue. Together, these innovations reflect CoStar Group’s vision for a new generation of real estate experiences powered by proprietary data, advanced AI and deep consumer engagement.
