Abstract: A system and method for automatically extracting product information from email receipts for resale purposes. The disclosure simplifies the resale process by automatically identifying purchase receipts in a user's email account, extracting relevant product details, and facilitating easy listing of items for resale. Where no email is present, image recognition applied to images of paper receipts and/or physical products themselves further supplements a user's digital inventory. This automation reduces manual entry errors and significantly improves efficiency for users looking to sell previously purchased items.

Abstract: A system and method for dynamically determining and presenting resale values through a browser extension interface on retail platforms. The browser extension injects a floating interface element into a host web page of a retail product to display real-time resale valuations while users shop online. In particular, the browser extension generates resale estimates and/or projected costs of temporary ownership of an identified product on the host web page. The browser extension progressively displays information where, in response to detecting user interaction with the floating interface element, the browser extension expands to present further valuation metrics and/or secondary sale listings through dynamically generated overlay windows.

Abstract: A recommendation system identifies resale goods corresponding to retail goods being viewed by a user on a retail goods website. Retail goods metadata and images are extracted from the retail goods website using heuristics and LLM-based methods. The extracted retail goods data undergoes ML model-based product category classification, intelligent image cropping, and color detection. Vector embeddings are generated for images and text using ML models and compared to resale goods vector embeddings stored in a vector database. Multiple result sets are retrieved, fused, and re-ranked using LLM-based and preference-aware re-ranking. A data pipeline continuously loads, cleans, and processes resale goods inventory from resale goods websites.

Abstract: A system and method for an integrated subsystem that identifies resale consumer goods available for sale whereby picture or text descriptions of items of firsthand consumer goods may be used as an input or search query where a user may enter size, style, and color parameters for clothing and fashion items. The plug-in uses a web crawler to maintain a database of resale consumer goods for sale and may isolate a single clothing item from a clothed person to perform a search query for resale versions of that item as well as provided improved specifically tailored results based on what the user is looking for at that specific time.
