Stop memorizing. Start mastering.

Lexora uses spaced repetition - the same science behind medical school flashcards, to help you learn 3,400+ SAT words and actually remember them. It figures out exactly when you're about to forget a word and quizzes you at the perfect moment.

Quick sessions, lasting results.

HOW IT WORKS

Lexora schedules your reviews automatically. New words are introduced gradually, and struggling words come back more often. You just show up, the algorithm handles the rest.

Four ways to practice: type the answer, fill in the blank, or pick from multiple choice. A built-in hint system nudges you without giving it away, and typo detection means one wrong letter won't ruin your streak.

WHAT'S INSIDE • 3,400+ curated SAT words across 4 difficulty packs • Every word comes with definition, example sentence, etymology, and a memory tip you can edit • Search by meaning - type "feeling happy" to find "elated" and "jubilant" • Text-to-speech pronunciation for every word

KEEP THE STREAK ALIVE Daily streaks keep you accountable. Miss a day? A one-day freeze has your back. Earn 14 badges along the way and share them with friends.

PRACTICE YOUR WAY Beyond the daily session, a practice hub offers four modes: drill all studied words, target your weakest vocabulary, preview new words, or take a random 5-word quiz. Practice sessions don't affect your schedule experiment freely.
