    paper AI Assistant in Homeshow field

    AI-powered listing assistant that lets users simply take a photo or video of a product. The assistant uses computer vision and natural language processing to identify the item, auto-fill listing fields (title, specs, value), and even suggest optimal pricing, auction settings, and shipping methods. Users can edit listings via voice commands or text, and the system learns from user preferences for future listings.

    The assistant reduced listing creation time by over 50% and increased listing accuracy by over 40%. With over 90% image-based product match accuracy and 95%+ voice command recognition, the tool significantly improved user satisfaction. The solution laid the groundwork for AI-driven automation across The Home Show’s marketplace, including future enhancements like dispute resolution bots and shopper assistants.
