Vocabulary,
reimagined.
Three steps to a bigger vocabulary.
Take the placement quiz
A quick check tunes the deck to words you actually need — no easy wins, no impossible jumps.
Swipe a few cards a day
Right if you know it, left if you don't. We surface the hard ones again until they stick.
Hit checkpoints, level up
Mini speaking & writing tests prove mastery and unlock XP, ranks, coins, and avatars.
Based on self-reported practice-section scores from 1,200+ beta users who used Lexiq at least 5 minutes a day.

Built like a game. Works like a tutor.
Personalized deck
A placement quiz tunes every card to your level — no wasted reps on words you already own.
Swipe to learn

AI checkpoints
Define it, use it in a sentence, or say it out loud. AI grades every dimension.
Streaks that stick
Daily streaks, gentle nudges, and freeze tokens so one bad day doesn't break you.
Ranks & XP
Climb from Novice to Wordsmith. Every word you master moves a real progress bar.
Coins & avatars
Spend coins on avatars, themes, and boosts. Make the grind feel like a reward.
