fillmein, the crossword constructor that scores its fill
A browser-based crossword builder with scored word lists, grid-aware autofill, clue management, and export to .puz, .ipuz, and .jpz.
Field notes
The constructor separates grid work, clue management, and export into distinct tabs. Its autofill draws from more than half a million scored words, showing both the words that fit an entry and which candidates remain compatible with the rest of the grid. Existing .puz, .ipuz, and .jpz files can be imported, while finished puzzles can be printed with an answer key or shared through an account-free solving link. A published-puzzle browsing feature is listed as forthcoming.
