🎥Joining class & classroom features

No need to install Zoom or Meet: the classroom runs in your browser (Chrome, Edge, Safari) on a computer or phone. A computer with a headset is best for comfortable screen sharing and whiteboard writing.

Joining class

1. 1

   Step 1

   Click Join class on the Tutor hub (or open the lesson from a reminder notification)

   The room opens 5 minutes before the lesson. If you arrive earlier, the lesson page tells you when the room opens — come back on time and the room appears by itself.

   Step 2

   The room connects automatically — turn on your mic and camera in the control bar

   When you join, your mic and camera are both off. When the browser asks for camera / microphone permission, click Allow. If the browser blocks sound, click Tap to enable sound.

   Dropping off or reloading the page for under 2 minutes still counts as present. If you leave the class by mistake, click Rejoin class.

Main features

1. 1

   Step 1

   Learner controls: click ⋯ on the learner's video tile

   Choose 🔇 Mute student, 📷 Turn off student's camera, 🎙️ Ask to unmute or ✋ Lower student's hand (when the learner has their hand up). You can't turn their mic on for them — you can only ask, and the learner turns it on.

2. 2

   Step 2

   Whiteboard: click Board

   Tools: select / move, freehand pen, straight line, arrow, rectangle, circle, T for typing text, eraser, insert image (up to 12 images). 5 colours, 3 line sizes. Add up to 20 pages; the ⬇️ button downloads the current page to your device as a PNG image.

   Both of you can draw. Each person can erase their own strokes; the tutor can erase any stroke, and only the tutor has the clear-page button. The board is not saved on the server — to keep it, download the image before the lesson ends.

3. 3

   Step 3

   Chat & files: click Chat, send files with the 📎 button

   Files up to 5 MB, kept for 7 days: images, PDF, Word, Excel, PowerPoint, TXT, CSV. After the lesson, the files are on the lesson page.

   With a new learner, file sharing unlocks after your first paid lesson together. Messages containing phone numbers, emails, Zalo and the like are blocked — all communication needs to stay on Zasu.

4. 4

   Step 4

   Lesson notes: click Notes, type while you teach, click Save & send to student

   Your typing is kept as a draft as you go; the learner only receives it when you click save or when you leave the class (it saves automatically). Attach homework files in the form right below the classroom — see Lesson notes & homework.

   Step 5

   Camera background: click Background

   Choose Light blur, Strong blur, a built-in image or Your image. Processing happens on your device; your video isn't sent anywhere.

Room opening / closing times & attendance

• The room opens 5 minutes before the lesson. Below the room it always says until what time the room is open.
• Joining late: the room extends automatically so you get the full lesson length, up to 30 minutes after the end time (15 minutes for a free trial lesson), and never overlaps your next lesson.
• Free extra time: if you are both still in the room when time is up, it extends by 5 minutes at a time, up to 60 minutes. In the last 5 minutes a yellow bar counts down “The room will close in about … min.”
• Automatic attendance: the system records when each side joins / leaves (the 🕒 Room attendance section below the room) and uses it to settle the result automatically 24 hours after the lesson — tutors have no “confirm completed” button.
