About Javu: Learn words your way
What Is Javu
Javu is a language learning app built around a simple idea: you study the words you actually meet. Instead of working through a fixed deck someone else assembled, you add your own words, plus the images and example sentences that give them context. Javu then turns that raw material into interactive quizzes.
The app layers two things on top of your personal word list. One is AI driven personalization, which reads your entries and shapes the question formats around them. The other is spaced repetition, a scheduling method that brings tricky words back more often and lets easy ones fade into the background. Together they aim at the same complaint most learners have: you study a lot and still forget.
The catch is that Javu is only as useful as the material you feed it. It won't hand you a ready made beginner course or a full grammar syllabus, so it works best for people who already have words to collect, from a class, a book, a job, or daily life. It runs as a mobile app on iOS and Android, and the official site and stores don't spell out a public API.
Getting Started
- Download Javu from the App Store or Google Play and create an account.
- Add words you want to learn, and attach an image or an example sentence so each entry carries context.
- Let Javu build quizzes from your entries, mixing formats like gap fills and puzzles.
- Study your daily set, and let spaced repetition decide which words come back and when.
- Keep adding new words as you meet them, since your list is the engine behind every quiz.

Key features
Personalized quizzes from your own words
The core of Javu is that you supply the vocabulary and it supplies the questions. You add words together with images and sentences, and the app turns them into interactive quizzes rather than static flashcards. That means the quiz reflects what you actually need to learn, not a generic word list.
AI driven personalization
Javu reads the entries you add and adapts the quiz around them. The app uses your words, along with their images and sentences, to shape how questions are built, so the practice stays tied to your context. For anyone who has tried a one size fits all vocab practice app, or treated a flashcard alternative as just a nicer looking deck, this is the feature that makes the drills feel less random.
Spaced repetition scheduling
Javu spaces your quizzes so that words you get wrong come back sooner and words you know well show up less often. The goal is to hit the sweet spot between forgetting and overstudying, which is why the app claims you can study less and still remember more. It's the same principle behind established flashcard systems, applied automatically.
Game style question formats
Questions change shape as you go, from gap fills to puzzles, so a review session doesn't feel like the same drill on repeat. Varying the format keeps you from memorizing the question instead of the word, and it makes a daily session easier to sit through.
iOS and Android apps
Javu is a mobile first product, with apps on both the App Store and Google Play. You add and review words from your phone, which fits the way most people collect vocabulary during the day. There's no desktop client or public API documented, so the phone is the main place you use it.
Context you control
Because you attach your own images and sentences, every word arrives with meaning already attached. That context is what separates a word you recognize on a card from a word you can actually use, and Javu keeps it at the center of each quiz.
Pros and cons
Pros
- Builds quizzes from your own words, images, and sentences, so practice matches what you actually need to learn.
- Spaced repetition scheduling brings weak words back automatically, which targets retention rather than raw volume.
- Varied question formats, from gap fills to puzzles, keep review sessions from feeling repetitive.
- Mobile apps on both iOS and Android make it easy to add and review words during the day.
Cons
- You have to supply your own vocabulary, so there's no ready made beginner course or grammar syllabus to follow.
- No public API is documented, which limits it for anyone who wants to plug vocab practice into another tool.
- No desktop client, so learners who prefer a keyboard and a big screen have to work from their phone.
