The questions students ask
What it is like from the seat, answered plainly.
No. There are no student accounts in Diaposi at all. You join with a QR code or a six-character code your lecturer shows on screen, and that is the whole process — no sign-up, no email address, no password to forget before next week's lecture.
No. Diaposi runs in the browser on any phone, tablet or laptop. Nothing to download, nothing to update and nothing taking up space on your phone.
No. Diaposi is free to use, with no participant cap, so there is nothing to pay and nothing that runs out halfway through a semester.
You can join at any point and you are put straight onto the slide the room is on. If you drop out and come back, you are resynced to the live slide with everything you had already marked still there.
It is a web page, not a video call. Any browser on any phone, tablet or laptop, and nothing to install on either side.
There are no student accounts or student emails. Your activity is attached to a random identifier that exists only for that session, not to your name. The presenter sees classroom activity and pseudonymous contributions; your private note text stays on your device.
They see the questions in the queue, because that is the point of a shared queue — but with no name on them. What you marked on each slide and what you wrote in your notes is yours alone.
It cannot. No student records are collected, and nothing you do in a session is attached to you in the first place, so there is nothing that could be graded, exported to a university system or held against you.
None that identifies you. No accounts, no email addresses, no cookies, no tracking and no student records. There is nothing to leak and nothing for you to consent to, and the platform is built and hosted in Europe under GDPR.
Yes. Notes are written on the slide they belong to, and nobody else can see them — not other students and not the person presenting. They come back to you, and only to you, in your end-of-session report.
They land against the exact slide the room is on, so the person presenting can see the moment something stopped landing rather than finding out in the exam. One tap says understood, lost, interesting, or that you have a question — which is a much lower bar than putting a hand up in a room of two hundred.
It goes in the queue like any other. The queue is sorted by up-votes, so questions the room shares rise first, but nothing is deleted for being asked by one person — and the person presenting can see the whole queue.
No, deliberately. Nothing is ranked, scored or shown publicly. The students who most need to say “I did not follow that” are the least likely to do it in front of the room, and a leaderboard is exactly what stops them.
Your screen shows the slide the lecturer is on and the controls under it, nothing else. It is the one honest answer to a phone already being out: a reason to look at the lecture on it rather than away from the lecture.
Your own report: every slide presented, what you marked on each one, the notes you wrote against them, the slides you flagged to revisit, and the questions the room asked. It is ready when the session ends, not the following week.
Yes, it exports as a PDF, so it goes wherever the rest of your revision already lives. It is a document you keep rather than something you have to log back in to read.
Please do — that is how most courses start using it. Send them the lecturer's page: it takes the .pptx or .pdf they already teach from, so there is nothing for them to rebuild and no reason for the answer to be “not this semester”.
Every seat gets a voice.
No account, no app, nothing to install. Just the code on the screen.
