The control console
A course started with one gesture. Everything else is automatic.
The tablet mounted in the classroom does it all: as soon as the teacher taps Join, capture starts, students receive the course live, and recording begins across all connected campuses. At the end of the session, one tap closes the course. The replay is available immediately.
Automated schedule
Courses appear with zero manual entry. As soon as a session is created, it’s visible to all learners concerned.
One click to join
Whether live from a campus or remote, the learner joins their session in one click, from any device.
Replay available immediately
The recording is chaptered and available on the LMS as soon as the course ends. No manual work required.
