How it works

How does BahasaSystem.com work?

BahasaSystem.com is free and works without an account. Below you'll see briefly what each feature does and how you use them together to learn Indonesian and Malay fast.

What can you do?

Words Flashcards with 1,500 words in three levels and 41 themes: greetings, numbers, food, travel, verbs with me- and ber-, work, society and the formal register. Choose the direction (English → Indonesian or the other way round) and how many cards you want. Every word shows the Indonesian word, the Malay equivalent when it differs, the translation and audio. Indonesian vs Malay Bahasa Indonesia and Bahasa Melayu share most words, but hundreds of everyday words differ. This list shows exactly those, side by side, so you learn one language and understand both. Quiz Multiple-choice questions with instant feedback. A quick way to test what you already know and where the gaps are. Time & dates Interactive trainers for telling the time (pukul, lewat, kurang, setengah) and saying the date (tanggal, hari, bulan, tahun) in Indonesian — with the Malay differences pointed out. Articles Short conversations and news items to read and listen to. Toggle Indonesian, Malay, a word-for-word literal layer and English separately, play the whole text, and tap any word to add it straight to your deck. Interval Study Your own smart practice deck. The FSRS system schedules every word exactly when you're about to forget it, so you repeat efficiently. Free decks hold up to 200 cards; Premium is unlimited.

Remembering: favourites, pipeline and Interval Study

While you practise, you automatically build up your own study material:

♡ Favourites — mark words you want to save to practise separately.
✚ Personal Deck — tap any word in an article or in the word popup to save it, even before it has its own flashcard. Add your own words too.
🚚 Pipeline — words you got right three times in a row move on automatically. Ready to move into your Interval Study deck.
📚 Interval Study — your main deck with smart repetition (FSRS). View your cards in the list and track your progress in the statistics.
💾 Saved decks — save your mistakes or a selection as a temporary deck and practise it again later. They're available straight from the homepage.

The smartest way to learn

Start with the beginner lists — greetings, numbers, everyday verbs. Those are the words you need most often.
Do 10 minutes every day rather than an hour once a week. Short, regular sessions stick better.
Press 📚 on words you really want to remember. They go into Interval Study and are repeated at the right moment.
Open Interval Study every day and finish whatever is due. That way you make the most of the smart repetition.
Practise in both directions: Indonesian → English trains recognition, English → Indonesian trains active knowledge.
Once the beginner words stick, move on to the intermediate lists: the me-/ber- verbs and the pe-/ke-an nouns show you how Indonesian builds words, which makes the rest much easier.
Going to Malaysia too? Run through the Indonesian vs Malay list so the differences don't catch you out.
