Five kinds, launched in a moment: true or false, multiple choice, a rating scale, an open answer or a live word cloud. Answers arrive from every phone in the room as they come in, and every poll you launch stays in the session's history.

How Diaposi Session makes your presentation interactive
The deck you already present from, up to 50 MB, shown as it is. Nothing to rebuild, nothing to convert by hand and nothing to install.
Everyone joins from their own phone, tablet or laptop, in the browser. No app to install, no account to create and no name to give.
Diaposi prepares polls and quizzes from your own slides. You read every one before it reaches the room, and can rewrite it, remove it or write your own.
Run polls, questions and quizzes from the cockpit while everyone follows your slides on their own screen. When you end the session, the report is ready, slide by slide.
Built from your slides. Take the whole presentation or only the chapters you covered, choose the difficulty and the number of questions, or let the room vote on both. You check every question before it goes out, rewrite or remove any of them, or write the quiz yourself. The answers stay hidden until the end.
Participants ask from their own phone, on the slide in front of them, without giving their name. When several of them ask the same thing, it becomes one question with their number on it, so you see first what most of the room is asking. One tap takes you to the slide it came from, another marks it answered.
A live check on understanding, on the slide in front of the room: participants signal that they follow, need clarification or are struggling. You see how many have responded, how many want you to go over it again, and whether the room looks confident or split, while there is still time to act.
Draw or write on the slide, add a photo or open a whiteboard on the spot. A timer, with music if you want it. The history of every poll and quiz you ran. The join code, back on screen for whoever arrives late. And the session settings: the time between two comments, whether participants may browse ahead, and raised hands.
Test the room with a live quiz from your own slides
Diaposi writes the quiz from your own slides, on the spot. You pick the whole deck or only the chapters you covered, then set the difficulty, the number of questions and the time each one gets, or let the room vote on it. Every question is yours to read before it goes out, and you can rewrite, remove or add one. Then the room answers on their phones while you watch each question fill up, and nobody sees the right answers until the end.

Your slides, live on every screen
A code or a QR code
They scan the QR code on your screen or type its six-character code. No app, no account and no name to give.
Follow, go back, take notes
The slide you are showing opens on their screen. They can go back to an earlier slide, take notes and draw on it, and mark it Got it or Review.
Anonymous, on any device
A phone, a tablet or a laptop, in the browser they already have. What they send reaches you without their name, and their notes and drawings stay their own.
Post-session analytics
The session ends, the work goes on: Diaposi files it, measures it and keeps it ready for your next class.
Sorted into folders by AI
Diaposi reads each deck and files the session under its subject, so every subject gets a folder of its own: Biomedical engineering, Mobile development, Educational analytics. Each session keeps its date, its participation, its questions, its quiz and poll results and how far the room got through the deck, with its report one click away.
Compare two runs of the same lecture
Give the same lecture to two groups and Diaposi lines the two sessions up side by side: who took part, the engagement score, the “got it” votes, the questions asked and the time spent, then slide by slide, biggest gaps first. You see at once what your changes did.
Everything quantified and measurable
After every session you get a report: who took part, how attention held on each slide, what the room understood and which slides are worth teaching again. Download it as a PDF or a CSV.
Attention, slide by slide
Where the room held on and where it drifted, over the slides and over time.
Who stayed
How many were still with you at each slide, and where the biggest drop came.
Quiet signals
What participants did without pressing a button, like going back to re-read a slide, so the ones who never speak up count too.
Worth a second pass
The slides the room flagged, questioned or drifted away from.
Slide by slide
Every slide you presented, with its attention, its votes and its questions.
Participants
Each participant's activity, anonymous and numbered by the order they joined.
Polls and quizzes
What the room answered each time you asked.
Questions and comments
The whole discussion, in the order it happened.
Expectations
What the room hoped to take away at the start, and whether it did by the end.

Diaposi Session, answered.
What hosts ask most often before their first session.
Diaposi Session is part of Diaposi, the EdTech platform for interactive and measurable learning. Upload the PowerPoint, PDF or Word file you already have, up to 50 MB, and present it as it is, with nothing to rebuild and nothing to install. Your file is private by default: only the people who join your session see its slides. While you present, you run live polls, anonymous questions and quizzes on the same slides.
You can start a session from this page without an account, and creating an account to keep hosting is free. Participants never need an account: they join from their browser with a code or a QR code.
No account and no app. They scan the QR code on your screen or type its six-character code on a phone, a tablet or a laptop, in the browser they already have. There are no clickers or voting handsets to hand out: everyone uses their own device.
Yes. Nobody gives a name to join. Questions and reactions reach you without who sent them, and when several participants ask the same thing, it appears once with their number on it. Their notes and drawings stay private, and in your report each participant is a number, in the order they joined.
Yes. Diaposi writes the quiz from your slides, on the spot, for the chapters you choose and at the difficulty you set. You read every question before it goes out and can rewrite, remove or add any of them, or write the quiz yourself. Nobody sees the right answers until the end.
A report of the whole session, slide by slide: attention on each slide, who stayed, the slides worth a second pass, every poll and quiz, and the questions as they came in. You can save it, share it and export it as a PDF or a CSV, and a saved report is kept for 12 months after the session.
Each participant leaves with a report of their own, with what they answered next to what the room did, and their notes and drawings are saved for them.
