Trulia has rolled out deep learning and AI-based features on its site over the course of the last few years, with more advanced features coming online more recently. The most straightforward is its recommendation engine, which matches users with properties likely to fit their preferences. There is also a customer engagement model that assesses web data to determine the type and frequency of communication that users prefer. Then, there are the more complex models that are closer to AI. A natural language generation model automatically creates text for neighborhood descriptions on the site. One of the most advanced AI features is a computer vision model.
