Live slides for classes and workshops

Students squint at the projector, take photos of slides, and ask you to go back to the formula. Give them the slides, live, on their own screen.

The same lecture slide on a teacher's laptop and a student's phone
Your slide, on every student's screen.

Set up in a minute

  1. Upload your lecture slides (PDF or PowerPoint) on slidebyside.com.
  2. Share the link: on the board, in your course chat, or as a QR code on the first slide.
  3. Teach. Students follow your slide as you go.

Students don't need accounts or an app. They open the link and get a random name, like LunarPanda, which they can change to their own.

Let students look back

A student checks an earlier slide; one click takes them back to live.

Turn on Browse on their own and a student who missed the definition on slide 4 can go back and read it, while everyone else stays with you. One click brings them back to the live slide.

"Where exactly are you stuck?"

Ask a student to point. Their cursor carries their name, so you see exactly which line of the proof lost them. Or have them circle it with the highlighter. It works the same for a student in the room and one joining from home.

Keep the class in hand

Everything is set in People & permissions, for the whole class or for one student:

Workshops and study groups

In a workshop, leave drawing and browsing on and let people mark up the slides as they work through them. For a study group, anyone can upload a deck and hand everyone the clicker. It's free, so nobody has to ask the school for a licence.

Try it with your next deck

Free, no sign-up. Drop a PDF on the homepage, then open the link in a second window to see both cursors.
