Visualizer turns any phone into a document camera. Open it on the whiteboard and it shows a QR code and a join code — scan it on any phone, or type the code at sageteachers.com/join, and that phone becomes the camera. Point it at a book or an object and the picture appears live on the board in seconds. No app to install, no cables, and no dedicated visualiser to buy.
A visualiser is one of the most-used bits of kit in a primary classroom — for sharing a child’s work, modelling a method, or showing a small object to the whole class. The hardware is expensive and tethered to one board; this does the same job with the phone already in your pocket. Because pupils can join too, you can put a child’s own work on the board in seconds without carrying books to the front, then rotate, flip or zoom the picture to get it straight. Nothing is kept — photos live only for the session and are deleted when you close it.
How does Visualizer work?
Open Visualizer on the whiteboard and it shows a QR code and a join code. Scan it on any phone, or go to sageteachers.com/join and type the code, and that phone becomes the camera. Point it at a book and the page appears live on the board.
Do I need a document camera or special hardware?
No — any phone works as the camera. It connects over the web with a QR or join code, so there are no cables and no dedicated visualiser to buy.
Do pupils need an app or account?
No — they open the camera in a browser with a code, with no app to install and no login.
Is Visualizer free?
Yes — Visualizer is free to use. Sign in once and you can run it in any lesson.
Want children to mark their own photographed work? That’s Mark It. Like the pupils-on-devices format? Word Cloud and Scattergories both run the same way, with a join code on any phone.
