Diagnil is a GUI application to help solvers of diagramless crossword puzzles. It accommodates puzzles distributed electronically using several file formats (puz, jpz, xpf, and ipuz) as well as those distributed in print form. Although software for conventional crosswords has existed for years, the diagramless variant has received little attention. Diagnil attempts to fill that void. It lets you solve puzzles by entering words, placing them on a grid, and moving them around the screen until the final shape is achieved.
