About
Lexicon is an ad-free English thesaurus. It makes no third-party requests, sets no cookies and does not log what you look up. Words you have looked up keep working offline.
When you click from word to word, Lexicon uses the path you took to put the closest meanings first. The path stays in this browser tab and is forgotten when you close it.
