Abstract: A system that utilizes an AI image generator, a search engine, and an item design system is disclosed. A text description of an item is provided to an AI image generator, which creates an image based on the text description. In some embodiments, the image is updated based on a further text description of the item. The image may be provided to the search engine and the item design system. The search engine selects, from an item catalog, an item to recommend to a user based on a similarity of the image to items in the item catalog. For example, the search engine may apply a machine learning model to compare embeddings of the item image to embeddings of images of items in an item catalog. The item design system may recommend an item design based in part on the image generated by the AI image generator.

Abstract: Generating records of a tangible object in blockchain may be performed by a non-transitory computer-readable storage medium comprising instructions. The instructions, when executed cause a computing device to associate a unique physical tag with a tag identifier. The unique physical tag includes a substrate having a plurality of optically readable indicia disposed at random positions and having a fixed positional relationship within the substrate. The instructions, when executed cause the computing device to associate the tangible object with the unique physical tag including the tag identifier, by generating a record of the tangible object as a block in a blockchain uniquely associated with the tag identifier, where the blockchain is managed by one or more devices on a decentralized network.
