Nam Hoc — Learn English Vocabulary While You Browse

Are you a Vietnamese learner trying to improve your English? Nam Hoc turns every webpage into a vocabulary lesson. Instead of switching between tabs or opening a dictionary, just double-click any English word and get an instant translation — right where you're reading.

How It Works

Whenever you come across an unfamiliar English word, simply double-click it (or highlight a phrase). A small popup appears near your selection with:

- A translation from Google Translate
- A second translation powered by DeepSeek AI for a more natural, context-aware result

Pick the meaning that makes the most sense, or type your own Vietnamese translation. Then hit Add to list — and that word is saved to your personal vocabulary collection. You also earn +5 points every time you add a new word, so building your list feels rewarding from the very first click.

You can also add words manually from the Add tab inside the extension, which is great for words you already know you want to study.

Practice With a Game

Saving words is just the beginning. Nam Hoc includes a built-in vocabulary game designed to help you actually remember what you've learned.

Each game session has two phases:
- Phase 1 — Multiple Choice: Pick the correct Vietnamese meaning from four options
- Phase 2 — Typing: Type the Vietnamese meaning from memory

The game is smart about which words it tests you on — it prioritizes the words you struggle with most, so your study time is always focused where it matters.

Track Your Progress

Stay motivated with a full progress dashboard:

- Today's stats — words added, points earned, and games played today
- 7-day chart — see your activity at a glance over the past week
- Streak counter — track how many days in a row you've studied
- All-time totals — total words saved, points earned, and games completed

Consistency is key to language learning, and Nam Hoc makes it easy to see your momentum building day by day.

Why Nam Hoc?

Most vocabulary apps ask you to study in isolation. Nam Hoc meets you where you already are — reading the news, browsing social media, watching content online — and turns those moments into learning opportunities. Every unfamiliar word becomes a chance to grow your vocabulary, earn points, and get one step closer to English fluency.

It's lightweight, fast, and requires no configuration. Install it, start browsing, and let the words come to you.
