Abstract

An image of a receipt may be received by a service provider from a user device of a user. The receipt may be a record of a transaction between the user and a physical merchant. The service provider may extract text from the image and apply a predictive model trained on text data of historical receipts to the extracted text to identify keywords corresponding to items purchased in the transaction. The service provider may generate a shopping list for the user and/or may compare the keywords to descriptions of catalog items in an online catalog maintained by the service provider to identify catalog items that are the same or similar to the purchased items. The service provider may associate the catalog items with the user's account maintained by the service provider and generate a user interface to present on the user device that includes an indication of the catalog items.
