The classroom
An online classroom board your class can turn, label and write on.
Put a 3D model on the board and every student sees it move with you — live. Try it below.

Attendance that tells the truth
Know who stopped listening — and for how long.
A red ring on a student’s tile the moment the class leaves their screen — and their not-listening time in the register afterwards.
How it works
- During class, the student’s tile gets a red ring and the People panel shows their status.
- After class, the register sums it up: “5 of 6 joined · 1 joined late · 1 had time not listening”.
- You can filter the register by joined late, left early, not listening or didn’t join.
Honest by design: Jaber only knows whether the classroom page was visible. It never claims what the student was doing instead.
Reach them in seconds
Ring a student from the room. It rings on their laptop and their phone.
Someone missing? Ring them from the room, like a WhatsApp call — no phone numbers shared. One tap and they’re in.
How it works
- Ring every absent student at once with “Ring all absent” in the People panel.
- The call rings on every device the student is signed in on.
- A missed call appears in the student’s messages, with a link to the class.
Calls run on the same infrastructure as the classroom — nothing leaves Jaber.

A frog on the left, your handwriting on the right — and the class sees both, live.
Place a model from Jaber’s library on the board, turn it, label it and write beside it — every student sees it live. This one is real: turn it.
How it works
- Turn, slide, label and reset a model right on the board — no separate app.
- Place two or more models side by side, and resize each one.
- Write your own labels, such as Eye or Hind leg; edit or delete them, and students see every change.

New · Group discussions
Split the class into groups. Hear every one of them.
Set a question and a timer; students talk in groups that hear only each other. Listen in, message a group, speak to all — then bring everyone back.
“Three conversations, one classroom — and the teacher can hear every one.”
Listen in“The quiet ones talk in a group of three. Then a speaker tells the whole class.”
Every voice“One tap brings everyone back, mid-sentence if it has to.”
Bring everyone back
PDFs students write on
Import a PDF. Write on it. Let students write too — and see who wrote what.
Open a worksheet on the board, hand the pen to the class, and see each student’s answer in their own colour.
How it works
- Any PDF becomes pages on the board: notes, past papers or textbook scans.
- Each student writes in their own colour, and only the teacher sees who wrote what.
- Lock a page so nobody can scribble over the worksheet.
Paper that matches the subject
English four-rule for handwriting. Graph paper for maths. Tamil four-rule too.
Four-rule for handwriting, graph paper for maths, in three sizes — on a light board or the blackboard.
How it works
- Graph paper has a darker line every five squares, so counting is quick.
- Every page starts on a darker line, so a graph that crosses a page break has no gap.
- The lines are fainter than any pen, so an axis you draw always stands out.
