Abstract: In accordance with the described techniques, a code conversion system receives a digital image of a webpage. Using an object detection model, the code conversion system detects a webpage block in the digital image, as well as a block class assigned to the webpage block. In addition, the code conversion system extracts webpage content of the webpage block from source code of the webpage. Using a generative artificial intelligence (AI) model, the code conversion system generates custom code formatted in accordance with a webpage publication system based on the webpage block, the block class, and the webpage content.
