Teaches every subject the same way: shows the thing first and names it after, uses real numbers and real examples, and never moves on while you are still lost.
One teacher for every subject, with one way of explaining things: show it before naming it, and never move on while you are still lost.

Your teacher
Teaches every subject the same way: shows the thing first and names it after, uses real numbers and real examples, and never moves on while you are still lost.
Grouped by area. Open one to see its subjects.
Listen to each one, then pick the voice you like. Every lesson on this device will use it.
The same four things happen in every subject, at every age.
Each idea is shown before it is named: on a board, with a picture, a diagram or a real example.
Short questions along the way. When an answer shows a gap, Lessi goes back and explains it another way.
A preschooler, a high-school student and a university student each meet the subject at their own level, in Hebrew or in English.
After the lesson: a worksheet to practise with, and progress saved on your learning path.
No. Lessi is a computer-generated character, an AI teacher. He is patient, never in a hurry, and checks that the learner understands before moving on, at whatever age.
Your first 60 minutes with the teacher are free, and no card is needed. The written lessons are free to read for everyone.
Every stage of learning: the early years (about ages 3 to 5, with a grown-up beside them), primary school, middle and high school including Bagrut preparation, and university-level courses such as calculus, linear algebra and statistics. For a child under 13, a parent opens the account.
Maths, reading and language (Hebrew, English and Arabic), science, history, computing, arts and more: over 190 subjects, from first numbers and letters to Bagrut exams and university courses.
Lessi is a computer-generated character, not a real person.
