For the tutor
Exercises from your material
Paste a text, upload a PDF or a photo of a textbook, or name a topic — the AI suggests exercises for the student's level: gaps, multiple choice, matching, sorting sentences into groups. You review the draft and save the lesson.
Live lesson
You and the student open the same lesson. The student's answers appear on your screen at once, pages turn together, audio and video play for both. Video call and chat are right in the lesson.
Homework in one click
Send any exercise of the lesson as homework. The student does it on their phone and hands it in; you see what is right and what is not, and can allow another try.
Students without sign-up
Add a student by name and send them a link — they are in the lesson straight away. If they sign up later, everything they have done stays with them.
English placement test
Five parts from A1 to C1, checked by fixed rules. After the test you see the student's level — overall and by skill.
Everything for lessons, together
Lesson schedule, students' word lists, word games, voiced dialogues and AI pictures for exercises.
For the student
