CoStar Group has launched Apartments.com Ai, a conversational artificial intelligence experience designed to transform how renters discover, evaluate, and lease apartments. The new tool replaces traditional search filters and keyword inputs with real-time, natural language conversations, aiming to function as a trusted rental advisor. By leveraging Apartments.com's extensive multifamily data, the platform offers personalized recommendations and guidance throughout the rental search journey.
AI-Powered Search Capabilities
Apartments.com Ai is available to every visitor on the Apartments.com platform. It understands renter preferences, answers complex questions, compares communities, and surfaces relevant recommendations. The system allows users to describe their ideal living situation in natural language, such as requesting a quiet apartment near restaurants or a pet-friendly community under a specific price range, to receive tailored suggestions.
Enhanced Property Evaluation
Beyond listing discovery, the AI assists renters in evaluating options with greater confidence. It can answer detailed questions about properties and neighborhoods, compare similar communities, and guide users through immersive Matterport 3D Tours and rich media experiences. The platform also facilitates direct contact with properties, streamlining the leasing process.
Strategic Development and Context
The development of Apartments.com Ai was informed by insights from an earlier AI-powered smart search experience and extensive consumer testing. This launch builds on CoStar Group's broader investment in artificial intelligence, following the introduction of Homes Ai earlier this year. Together, these innovations reflect CoStar's vision for a new generation of real estate experiences powered by proprietary data and advanced AI.
