Learn Indonesian
the way people
actually use it.

A real-time speech coach that helps you move from textbook to natural conversation.

You said:

"saya ingin menggunakan itu"

πŸ””

Try this instead:

"Eh, gue mau pake itu!"

Courses teach formal.
Locals speak casual.

What you learned

"saya ingin menggunakan itu"

πŸ“š Textbook correct. Stiff. Formal.

What locals say

"gue mau pake itu"

πŸ—£οΈ Natural. Casual. Real.

Indonesian courses teach you "saya" and "anda" β€” words locals rarely use in everyday conversation. The result? You sound like a textbook, not a friend.

⚑ Layer 1

Feedback in
milliseconds.
Not minutes.

The app listens as you speak. Say a formal word, get the casual version instantly β€” a buzz and a voice cue before your sentence even ends.

Listening...

"saya mau..."

πŸ“³Instant correction

"Eh, gue!"

Before

"Saya ingin bekerja di sana."

After

"Gue mau kerja di sana."

Why it works: "Gue" is the casual Jakarta pronoun. "Kerja" drops the "be-" prefix β€” nobody uses it in daily speech. Sounds way more natural.

🧠 Layer 2

Speak.
Then learn
why.

After each sentence, the AI breaks down exactly why the casual phrasing sounds more natural β€” not just what to say, but how locals think about it.

Built for real conversation.
