Busuu vs Wordie: A Full Language Course or a Vocabulary Tool for the Web?

Busuu and Wordie are not really competitors. Busuu is a complete language course that takes you from your first words through grammar, listening and speaking, with feedback from native speakers. Wordie is a small Chrome extension that does one job: it captures the English words you meet while browsing and keeps them in front of you until they stick. If you are starting a language, Busuu is the better tool. If you already read English online and keep meeting words you half-know, Wordie fits better.

Quick verdict

• Pick Busuu if you are a beginner or lower-intermediate learner, want a clear path from level to level, need grammar explained, or are learning a language other than English.
• Pick Wordie if you are intermediate to advanced in English, read a lot on the web, and want to save and review the exact words you encounter, with no account and your data kept in your browser.
• Use both if you are taking a course but also read real English material: the course covers the core, the extension covers everything the course never mentions.

What is Busuu?

Busuu is a language-learning platform available in the browser and as iOS and Android apps. It offers courses in over a dozen languages, including English, Spanish, French, German, Japanese and Korean. Lessons are organized by level and mix vocabulary, grammar, dialogues, listening and short exercises.

Its best-known feature is the community: you can submit written or spoken exercises and native speakers of that language correct them, while you correct learners of your own native language. Reviewers consistently praise this, though the quality of corrections varies from person to person.

Busuu uses a freemium model. The free tier gives access to core course content and community feedback. Paid plans add tools such as vocabulary and grammar review, offline lessons, an ad-free experience and, on the top tier, AI conversation practice and pronunciation feedback. Prices vary by country, plan and billing period, and discounts are frequent, so check the current price in the app before subscribing.

What is Wordie?

Wordie is a browser extension for Chrome and other Chromium browsers (Edge, Brave, Arc). You select a word on any web page and a card shows its definition, part of speech, synonyms and related words, with a Save button. From then on, that word is highlighted whenever it appears on any page you visit, which is what we call contextual highlighting.

A recall mode turns saved words into flashcards: you try to remember the meaning, reveal it, and rate yourself Forgot, Hard or Easy, which updates a 0 to 100% mastery score per word. The dashboard lists your words, lets you add words manually, shows the last seven days of activity and exports to CSV or JSON. Everything is stored locally in your browser; there is no account and no Wordie server receives your word list.

Wordie is free for up to 20 saved words. Pro is a $12.99 one-time purchase for an unlimited vault, full recall mode and analytics, and a Student plan costs $0.99 per month.

Busuu vs Wordie at a glance

How each one teaches vocabulary

Busuu: words chosen for you

In Busuu, the course decides which words you learn and in what order. That is a strength at the start. The first two or three thousand word families cover most everyday language (see how many words you need to be fluent), and a curriculum makes sure you meet the high-frequency words first, with grammar and audio around them. The paid vocabulary review tool then quizzes you on words from your lessons and brings back the ones you struggle with.

Wordie: words chosen by your reading

Wordie has no curriculum at all. Your word list is whatever you selected while reading: mitigate in a news article, idempotent in API documentation, perfunctory in a novel excerpt. That makes it a poor tool for a beginner, who does not yet read enough English to find useful words, and a good one for someone past the intermediate plateau, where the remaining words are too rare and too personal for any course to predict.

The highlighting matters here. Research on incidental vocabulary learning suggests a word usually needs several meaningful encounters before it sticks. Seeing a saved word marked on a new page, in a new sentence, turns those encounters into deliberate ones.

Review and memory

Both tools use some form of active recall. Busuu's review quizzes present words from your course and adjust which ones come up based on how you did. Wordie's recall mode is a simple flashcard loop with a mastery score; it is not a full spaced repetition scheduler like Anki's, and we do not claim it is. If you want precise interval scheduling, you can export your Wordie list to CSV and import it into Anki (see how to import words into Anki).

Where Wordie adds something different is outside the review session: because saved words are highlighted everywhere, your normal browsing becomes extra, spaced exposure without scheduling anything.

Privacy and accounts

Busuu needs an account, which is what lets your progress follow you between phone and laptop and lets community members correct your work. That is a fair trade for a course.

Wordie takes the opposite approach. There is no sign-up, and your vault lives in your browser's local storage. The downside is real: there is no sync, so words saved on your work laptop do not appear on your home computer unless you export and re-import them.

Where Busuu is clearly better

• Starting from zero. Busuu gives you a learning path, grammar explanations and audio. Wordie assumes you can already read the page.
• Languages other than English. Busuu teaches over a dozen languages. Wordie's dictionary is English only.
• Speaking and writing. Native-speaker corrections and, on higher plans, AI conversation practice train production, which Wordie does not touch.
• Mobile. Busuu has full phone apps. Wordie has no mobile version.
• Certificates and structure. If you want visible levels and a sense of completing a course, Busuu provides it.

Where Wordie is the better fit

• Words from your own reading. Industry jargon, academic vocabulary and literary words appear in Wordie because you met them, not because a course writer guessed you might.
• Zero friction while browsing. Select, read the definition, save, keep reading. No switching apps.
• Privacy. No account and no server copy of your word list.
• Cost over time. One payment instead of an ongoing subscription.

Can you use Busuu and Wordie together?

Yes, and for an English learner around B1 to B2 it is a sensible combination. A realistic week might look like this:

1. Do Busuu lessons on your phone during your commute for grammar, listening and structured vocabulary.
2. On your computer, read one or two real English articles a day on topics you care about. Save five to ten unknown words with Wordie.
3. Spend five minutes in Wordie's recall mode in the evening, and let highlighting catch the words when they reappear.
4. Use Busuu's community to write a short paragraph that uses three of your saved words, and get it corrected.

That last step closes the gap between receptive and productive knowledge, which neither tool solves alone.

Conclusion

Busuu is a course; Wordie is a vocabulary habit for the web. Beginners and anyone learning a language other than English should pick Busuu. Intermediate and advanced English readers who want to keep the words they meet online, privately and with a one-time price, will get more from Wordie. If you are somewhere in between, the two complement each other well. For a broader view, see our roundup of the best vocabulary apps.
