Redfin's Conversational AI Search Drives 2x Listing Views and 47% More Tour Requests
Technology-powered real estate brokerage (Rocket Companies subsidiary), serving millions of homebuyers and sellers nationwide
The Challenge
For decades, online home search has forced buyers to think like database administrators — selecting from dropdown menus, setting exact square footage ranges, and drawing rigid map boundaries. This one-size-fits-all approach created enormous friction: buyers struggled to articulate nuanced preferences like 'good natural light' or 'cottage-like feel' through static filters, and agents had no way to understand the full context of what a buyer truly wanted. Redfin, serving millions of homebuyers across the U.S., recognized that this filter-based paradigm was leaving enormous value on the table — buyers were missing homes that matched their real preferences, and Redfin was missing opportunities to connect them with agents and services.
The Solution
In November 2025, Redfin launched a first-of-its-kind conversational AI home search experience, built in partnership with Sierra — an AI platform co-founded by Bret Taylor and Clay Bavor. The system replaces traditional filters entirely: the conversation itself becomes the interface. Buyers describe what they want in their own words, and the AI engages in a back-and-forth dialogue to refine results across millions of listings in real time. The AI understands fuzzy, human concepts — 'I want a modern kitchen,' 'I care more about overall space than bedroom count,' 'show me something with a cottage-like feel' — and translates them into precise property matches. When a buyer's criteria can't be met (e.g., a $300k home in a premium neighborhood with a long wish list), the AI proactively suggests adjustments like expanding the search radius or relaxing specific requirements. The system supports multilingual queries, integrates with Redfin's existing tools including Redfin Estimate, Ask Redfin, and Buying Power, and learns from real conversations daily to continuously improve its understanding of buyer intent. The platform launched on Redfin.com and mobile web, with iOS app support added in December 2025.
The Results
Conversational search users view nearly twice as many listings compared to traditional filter-based search users
Users are 47% more likely to request home tours or other Redfin services after using conversational search
Redfin reported $1.04 billion in annual revenue in 2024, a 7% increase over 2023
Lead agent counts grew 32% year-over-year in Q1 2025, supported by AI-driven lead quality improvements
“When you're buying a home, the options can be overwhelming. Conversational search lets us look across many more haystacks with far more detailed information about the type of needle each user is looking for.”
Key Takeaways
Replacing static filters with conversational AI dramatically increases buyer engagement — users explore more listings and convert to tours at a significantly higher rate
Partnering with a specialized AI platform (Sierra) allowed Redfin to deploy a sophisticated conversational agent faster than building in-house from scratch
AI that understands nuanced, human language ('cottage-like feel,' 'good natural light') unlocks preferences that traditional filter systems can never capture
Proactive AI guidance — suggesting search adjustments when criteria can't be met — builds trust and keeps buyers engaged rather than frustrated
Continuous learning from real user conversations creates a compounding improvement loop that makes the AI more accurate and useful over time
Integrating conversational AI with existing tools (valuation, buying power, agent services) creates a seamless end-to-end homebuying experience
