System and method for document grouping and user interface

Systems and methods for grouping documents and/or displaying groupings are described herein. Documents may be grouped by their document character features. Document character features may include distinct character types, character counts, common character counts, character difference counts, missing character counts, and any combination thereof. Document matches may be based on a threshold value compared to a score and/or indicator based on document character features. The computing devices described herein may generate user interfaces for displaying clusters of documents. The clusters of documents may indicate matches between documents based on the document character features.
