How your teacher teaches you English

  • Explains in your language

    Explanations and corrections come in the language you speak; the phrases, the model scene and the practice are in English. As you advance, you hear more English.

  • Short spoken lessons

    Each lesson has a clear goal: a short model scene, new phrases on the board one at a time, then you use them yourself. The teacher waits for your answer and gives a hint before the answer.

  • Hears and remembers

    When you speak, the teacher helps with the sounds that need work, at your level. It remembers the mistakes you keep making and brings them back in your reviews.

  • Practice and Words

    Real-life situations and free talk in English, and the words from your lessons collected in Words for short daily reviews.

The English course, level by level

Try free for 7 days
  • The first 7 days of the first plan you buy are free. A payment method is needed to start, and the plan renews monthly unless you cancel; cancel before the free week ends and you pay nothing. On the web it is once per account and once per card: a card that has already had a free week, or a prepaid card, is charged from the first day.
  • Prices are in US dollars. The checkout or the store shows your local price and any tax before you pay.
  • Live voice minutes count while a lesson or practice session is open, whether you speak or type. A minute in which nobody speaks or types isn't counted, and the four tools never use minutes.
  • Monthly plans only, with no free plan. The Terms of Service have the details.

Frequently asked questions

Do I need to know any English to start?

No. The A1 course starts from your first words, and the teacher explains in the language you speak while the phrases you learn are in English. The app works in 12 languages, and the teacher can explain in any of them.

Where does the English course start?

The English course begins with first words: greetings, the alphabet, numbers and the days of the week. Its first module is “First words”, with the lessons “Hello”, “The alphabet”, “Numbers and age”, “Days and classroom words”.

How long are the lessons?

Lessons take from 15 minutes at A1 to 30 minutes at C2. The course has 292 lessons in 73 modules across six levels. Time alone completes nothing: a lesson is done when you have done its steps.

I already know some English. Can I skip ahead?

Yes. Take the level check, about 10 to 15 minutes with your teacher, or choose your level yourself. You can change it later; your place in the old course and your words are kept.

Can I practise speaking English?

Yes. Lessons are spoken by default, and Situations and Free talk let you hold real conversations in English. The teacher helps with your pronunciation at your level and never treats your accent as a mistake. You can always type instead.

How much does it cost to learn English?

Every plan includes every course: Tools at US$9.99, Classroom at US$19.99 and Classroom Plus at US$29.99 a month, with 30, 180 or 300 minutes of live voice. The first 7 days of the first plan you buy are free.

Is the teacher a real person?

No. The teacher is an AI, and the app always says so. No person reviews your lessons.
