Semantle is a daily word-guessing game built around meaning rather than spelling. Players try to identify a hidden word by entering single-word guesses, then use similarity feedback to judge how closely each guess relates semantically to the answer. The game uses artificial intelligence, specifically word2vec technology, to measure relationships between words. A proximity indicator appears when a guess is among the thousand words nearest to the secret word, and players can make unlimited guesses.

A new puzzle is released each day at 8 p.m. New York time. For more opportunities to play, Semantle offers an archive of previous games, as well as Semantle Junior for players seeking a different level of challenge. The site also includes statistics, team play, and tools for creating games, alongside account and settings features. Semantle was created by David Turner and is now part of The Word Finder, which also provides word games and solving tools, including an anagram solver and a Wordle solver.
