Lex Vocabulary

Lex turns SAT vocabulary from a chore into something you'll actually open every day. Every word is taught the way it's really tested: not just a definition, but the nuance, the roots, the traps, and a short reading passage that puts the word in context — the same way the SAT does. WHY LEX • A structured curriculum organized into Worlds — Foundations, Rhetoric & Reasoning, Character & Temperament, and more — that build on each other, with new Worlds added in regular free updates. • Multiple ways to practice every word: match the meaning, fill the blank, read it in context, and mini SAT passages that reuse words you've already learned. • Spaced repetition that brings words back right before you'd forget them. • A calm, encouraging design — no leaderboards, no shame. It's you vs. yesterday's you. MAKE IT YOURS • Earn credits by completing quests and hitting daily goals. • Spend them in the shop to dress up Lex, your study companion — hats, glasses, auras, and more. BUILT TO RESPECT YOU • Works fully offline. No account required. • No ads. No selling your data. No dark patterns. Whether you're aiming for a 1400 or a perfect 1600, Lex meets you where you are and grows the vocabulary that moves your Reading & Writing score. Lex launches with five Worlds of carefully crafted vocabulary, and we're adding more in free updates — so your word list keeps growing right alongside you.
