132 daily lessons from complete beginner to elementary (A1 to A2), written and recorded by a native Indonesian teacher, built on the Indonesian people actually speak. The first 6 lesson days are free.
Most Indonesian classes teach the language of the textbook: tidak, sudah, bagaimana. Most Indonesians say nggak, udah, gimana. Learners who finish a standard course can read a newspaper and still cannot follow a conversation at a warung. JADI's course is built to close that gap: every lesson teaches the standard form and the spoken form together, with Yohana's audio for every sentence.
It is a course, not a collection of exercises. The 132 lesson days run in order through 22 themes, each theme ending in a review day with a dialogue and a video. You start with a placement test, do one lesson day at a time, and the review system brings back what you learned before you forget it.
| Level | Lesson days | What you can do at the end |
|---|---|---|
| A1 Beginner 12 themes |
71 days: 58 lessons and 13 review days | Greet people and introduce yourself, order food, ask for and give directions, make requests, talk about your day, family and plans in simple sentences, and understand the spoken forms people use back. |
| A2 Elementary 10 themes |
61 days: 51 lessons and 10 review days | Describe people, feelings and relationships, talk about hobbies, entertainment, health, nature and past experiences, make plans, and hold an everyday conversation with a patient speaker. |
| Intermediate | In development | Longer dialogues, stories and the podcast carry you past A2 while the next level is being written. |
Not sure how long that is for you? Our guide on how long it takes to learn Indonesian gives hours by level, and is Indonesian hard to learn explains why the start is quick.
Every 5 or 6 days a review day ties the theme together with a dialogue and a video of Indonesians using it. A lesson day takes 15 to 30 minutes.
Every lesson in the course is written and recorded by Yohana, a native Indonesian teacher with more than 3,400 five-star reviews on iTalki. She writes the way she teaches in her one-to-one classes: around the sentences her students actually needed, with the spoken forms included from the first day rather than saved for "advanced". You can hear her in the JADI podcast, which is free.

The honest version: a course gives you the language, a person gives you the conversation. We recommend doing both, and our comparison of the best apps to learn Indonesian says where each one fits.
Is JADI an online Indonesian course or an app?
Both. It is a structured course of 132 daily lessons, delivered through the JADI app on iOS, Android and the web. You follow it in order, one lesson day at a time, like a class with a syllabus.
What level does the Indonesian course go up to?
From complete beginner to elementary: A1 (71 lesson days) and A2 (61 lesson days) on the CEFR scale. Intermediate material is in development. After A2 you can hold everyday conversations and follow most of what people say to you.
How long does the course take?
One lesson day takes 15 to 30 minutes. At one a day, A1 takes about ten weeks and A1 plus A2 about four and a half months. Review days are built in, so you do not need to plan your own revision.
Who teaches the course?
Every lesson is written and recorded by Yohana, a native Indonesian teacher with more than 3,400 five-star reviews on iTalki. There is no machine-generated content in the lessons.
Does the course teach formal or spoken Indonesian?
Both, side by side. You learn the standard form you will read and the spoken form you will hear, such as tidak and nggak, sudah and udah, so that conversations do not stall at the first reply.
How much does the Indonesian course cost?
The first 6 lesson days are free with no credit card. After that it is $7.99 a month or $59.99 a year, with everything included: all lesson days, reviews, stories, videos and the podcast.
Can I start at my level?
Yes. A placement test at the start puts you at the right lesson day, so a learner who already knows the basics does not sit through them again.
Your first 6 lesson days are free. No credit card required. Then $7.99/month or $59.99/year; see pricing.
