# Vocabulary Builder

> Grow a Focus Set of words you want to use, discover new ones, and watch your vocabulary grow over time.

**Vocabulary Builder** tracks the words you actually use when you speak — in lessons *and* in AI practice — and helps you deliberately grow. It's available on both the web app and the AI app, sharing the same data.

It has three tabs: **Focus**, **Discover**, and **Progress**.

## Focus

Your active practice list.

* **Vocabulary Capacity** — total words you've stabilized through focus practice.
* **Weekly Focus Target** — focus points earned this week (resets every Monday).
* **Focus Set** — up to 5 words that earn progress when you use them in speech. Each dot shows how close a word is to being acquired.
* **All Goals** — words you want to learn. Tap **+** to move one into your Focus Set and start tracking it.

<Tip>
  You earn progress on a Focus Set word by actually *saying* it — in a lesson or to an AI character. Pick words you can realistically work into conversation this week.

## Discover

Find new words to learn.

* **Search** any word to look it up.
* **Recommended for You** — AI-suggested words based on your goals, level, and activity, each with its part of speech, CEFR level, and a reason it's useful. Tap **Add** to send it to your goals.
* Browse **curated sets** organized by CEFR level and theme.

## Progress

See the long view.

* **Total / Unique / In Progress / Acquired** word counts.
* **Vocabulary Growth Over Time** — a chart of how your vocabulary has grown, with metric and date-range selectors.

This is the same vocabulary overview you see on your dashboard — it just adds the history and goal-management tools.
