Build Better Vocabulary for Real Life

English may not be your first language, but you use it in many parts of your life. And building your vocabulary gives you more words to understand, express your ideas, and communicate with confidence.

Have more ways to say what you mean.

Sometimes you know exactly what you want to say, but the right word doesn't come quickly. Build vocabulary that helps you explain ideas, contribute in meetings, write clearer emails, and communicate naturally at work.

English Can Open More Doors in Life

English is more than a language. It can connect you to opportunities, people, knowledge, and experiences around the world.

Nearly 30% of people worldwide speak English. That's more than 2.3 billion people who use English to communicate across countries and cultures.

English can help you:

  • Grow your career and access more opportunities
  • Work with people around the world
  • Study and learn from more resources
  • Travel and connect with people more easily

Why games outperform studying for vocabulary.

Four findings, in the order they build on each other.

  1. 01

    Spacing beats cramming

    Memory for new material decays within days unless it is revisited. A short daily round is spacing, whether or not it feels like study.

    Ebbinghaus, 1885
  2. 02

    Being tested beats re-reading

    Retrieving an answer builds memory faster than reviewing it. Every round asks you to produce the word, not just recognise it.

    Roediger & Karpicke, 2006
  3. 03

    Recognising a word is not knowing it

    Understanding a word you meet is not the same as reaching for it yourself. That gap is where most learners stall.

    Nation, 2001
  4. 04

    Effortful recall is what sticks

    Recall that takes a little effort lasts longer. Hence the timer, and a hint you have to ask for.

    Bjork & Bjork, 2011

Create an account. Own your progress.

Optional, but it lets the site remember which words keep catching you out and aim the next session at those.

Daily Streaks

Log in and play every day to keep your streak alive. Miss a day and it resets. Simple, and harder to ignore than you'd expect.

Points and Milestones

Correct answers add up, and milestones unlock as your vocabulary grows. Enough structure to keep you coming back on the days you would rather not.

Weak Word Tracking

WordSensei tracks the words you keep missing so you can focus where it matters, not drill words you already know cold.

Multilingual Interface

The games are in English. The interface is coming in more languages so you can navigate in your own language while you learn.

Sign in with Google or X, no passwords to remember.

Repetition builds vocabulary.
Games make you repeat.

When you're chasing a streak or racing a timer, you drill vocabulary without thinking about it. That's when retention actually sticks, not during a study session, but during play.

Common questions.

If something's still unclear, reach out. We're building this for real learners and the feedback helps shape what gets built next.

Yes, all three games and your progress dashboard are free to play. WordSensei is supported by the ads shown on the site, which cover our servers and development. We may add optional paid features for advanced analytics in the future, but the core will always be free.
Yes, and it is worth saying that most people who ask this are further along than they think. If you can read this page, comprehension is not your problem. What is missing is usually production: recalling the right word quickly enough to use it. Start with the easier word sets and work up.
Duolingo teaches a language from the ground up: listening, grammar, reading, the lot. WordSensei assumes you already have the language and are stuck on range, which is the usual position for someone who works or studies in English but did not grow up in it. Different problem, different tool. Using both is perfectly reasonable.
No. WordSensei runs entirely in your browser on desktop or mobile. Nothing to install, nothing to update.
English vocabulary is our focus for now. However, we're expanding the interface to support more native languages so learners can navigate the platform in their own language.

Tell us what you are stuck on

If a word set is missing something you need for your work or your studies, we would rather hear it than guess. Questions about the site are welcome too.
