ULU - Ultimate Lookup Utility

ULU is a word-lookup and tournament adjudication tool useful for a variety of word games, including Scrabble®, Words With Friends®, and crossword puzzles.

ULU comes equipped with both of the lexicons used in English-language Scrabble: the NWL2023 lexicon for North America, and the CSW2022 lexicon for the rest of the world.

ULU's Search page enables you to find words that match letter combinations, with or without blanks and wildcards. It also finds words matching any pattern you name, words that contain only a subset of letters you name, words of a certain length, or any combination of these things at once. You can also limit search results to show only the number of matches or to show which blanks make matches. Tapping a word brings up a page of more detailed information about that word.

ULU's Judge page lets you see whether or not words you type are all valid, as you would need when playing tournament Scrabble.

ULU also includes a customizable timer for use in tournament Scrabble or in other games
