LexoLab
The vocabulary lab in your pocket

Build the kind of vocabulary
people notice.

It's pretty simple. You learn a word, hear it, use it, and get quizzed on it in a bunch of different ways. Then it comes back right when you're about to forget it. That last part is the whole trick, and it's why the words actually stick.

Real meanings, real sentences

Plain definitions, an example sentence that actually uses the word, and synonyms and antonyms to round it out.

04 / 05

Quizzed every which way

Pick the meaning, fill in the blank, type it from memory, or spot its synonyms on a board of ten. Every angle makes it stick.

Reviews right before you forget

Each word gets its own review schedule. Get it right and the gap grows, from days to weeks to months, until it's yours for good.

Every level is a path. Here's what you'll pick up along the way.

Smart reviews

LexoLab keeps a separate schedule for every word you've met, so each one comes back exactly when it needs to.

  • Get a word right on the first try three times in a row and it counts as mastered.
  • Mastered words come back after 3 days, then a week, and the gap keeps stretching as long as you keep getting them right.
  • Miss one and it comes back sooner, so the words you struggle with get the most practice.

Etymology

Every word has a backstory. The etymology browser tells it.

  • Search any word to see where it came from and how it changed along the way.
  • The languages it passed through, like Latin, Old French or Old English, are picked out so the trail is easy to follow.
  • Knowing where a word comes from makes its meaning easier to remember.

Leagues

Every week you're put in a league with up to 30 other learners.

  • Everything you study earns XP, and XP is what climbs the table.
  • When the week ends, roughly the top 30% move up a tier and the bottom 30% move down.
  • Everyone's week starts and ends at the same moment, so nobody gets a head start.
