Abstract: A method for comparing documents using an AI model is disclosed herein. The method includes preprocessing a plurality of input documents into a structured, standardized format for comparison. Further, the method includes generating a layout of components in the plurality of input documents. Furthermore, the method includes generating a canonical representation indicating relationships between the components. Furthermore, the method includes determining sections within each of the plurality of input documents by segmenting the layout Furthermore, the method includes determining a textual difference matrix using the AI model, based on the comparison of the plurality of sections within each of the plurality of input documents, wherein the textual difference matrix indicates alterations in one or more expressions in each of the plurality of sections.
