Alpus is a dictionary viewer compatible with StarDict, XDXF, DSL, DICTD, and TSV/Plain dictionaries. All dictionaries are extracted, indexed, and optimized automatically using the "Import Dictionary" option of the "Options" menu. The profiles allow grouping of dictionaries without duplicating the storage space. You can edit and customize properties of a dictionary, such as the visible name. The application supports searching full-text of all dictionaries for exact matches.
