How Glotalot works

Glotalot grows your vocabulary in a language you’re learning by finding the words just beyond what you already know and training you on them a few minutes a day.

1. A two-minute placement test

You start with a short adaptive test. Pick the correct meaning, or tap “I don’t know” — being honest is what makes it accurate (some words are deliberately fake, to catch over-claiming). After the first handful of words Glotalot already estimates your vocabulary size and level; you can keep going to sharpen it.

2. Your frontier

From that estimate Glotalot locates your frontier — the band of words right at the edge of what you know. Those are the words worth learning next: not too easy, not hopelessly hard.

3. Daily training

Each day you study a small batch of new frontier words — with their full definition and example sentences — then a quick quiz. Words you get right are spaced out for review; words you miss come back sooner. Don’t want to learn a particular word? “I don’t want to learn this word” removes it for good.
