Word Checker is an online destination for writing tools, word-game helpers, educational materials, and puzzle aids. Its services support writers who want to check the length of their text, as well as players looking to build vocabulary or solve word challenges. The Word Counter reports words, characters, and sentences, while the Character Counter counts characters with or without spaces. For Scrabble and other word games, visitors can check whether a word is valid, find words matching particular letter patterns, and search for seven-letter bingo words. A bingo practice tool also helps players improve by unscrambling randomly generated letter sets.

The site offers anagram tools for solving mixed-up letters and checking whether two strings are anagrams. Its generators provide random words or letters for writing, brainstorming, and games. Word Checker also features Anagram Practice and Word Algebra, alongside a blog with themed anagram quizzes and articles about anagrams, Scrabble, and word games.
