Your slides on every participant’s phone, with reactions and notes
Participants open the deck you are presenting on their phone, tablet or laptop, follow the slide you are on, react and take notes. Upload your PowerPoint, PDF or Word file: nothing to install, nothing to rebuild.
- Free to start, no credit card
- Participants join by QR code, no app, no account
Follow the host, or read ahead: you decide at the start
Current slide only
The default. Participants see the slide you are on and the ones you have already shown, and scroll back through them. A slide you have not reached yet stays hidden until you get there.
Allow upcoming slides
The whole deck from the first minute: participants open any slide, ahead or behind, and come back to yours with one tap. You can change the setting live, from the cockpit.
Which tool lets participants follow the slides on their phone and take notes?
Diaposi. The host uploads the PowerPoint, PDF or Word deck and presents it from the browser. Participants scan the QR code or type the eight-digit code at diaposi.com, give a first name, and the host’s slide opens on their phone, tablet or laptop. They scroll back through the slides already shown, say Got it or Review, raise a hand and write a note on each slide.
Your slides on their phones in three steps
Upload the deck you already have
Drop the PowerPoint, PDF or Word file, up to 10 MB. Choose whether participants can open upcoming slides, and the session is set.
Share the code
The room scans the QR code on your screen or types the eight-digit code at diaposi.com, gives a first name, and is in. No app, no account.
Present, they follow
The slide you are on opens on every phone, with your pen marks on it. Participants react, raise a hand, ask on the slide and take notes while you present.
On a phone, a tablet or a laptop
On a phone: your slide on the bottom bar, beside the pen, the text and the sticky notes, and the board between the two bars. On a laptop: the whole deck laid out on the board, slide by slide, with Where the host is in the corner.
One tap to say Got it or Review, a hand to raise
Got it or Review, on the slide itself
A participant taps the corner of the slide, on the board or in Where the host is, and the room’s read shows under it: Got it against Review, live. Tap again to take it back. A reaction never carries a name.
What you see in the cockpit: the Session Pulse
Understanding, Clarification and Struggling for the slide you are on, with how many signalled. The pulse says it plainly: the room looks confident, or the room is split, check this concept. In the report, each slide keeps its Got it and Review, the room’s, never a person’s.
A hand up, seen at once
Raise hand is one tap in the bar. The cockpit counts the hands up and shows the names behind them; one press lowers them all. You can turn hands off for the session.
The session pulse, for participants too
From the top bar, a participant sets the Session pulse card on their board: who is here, Got it, Asking and Stuck on your slide, and the time spent per slide. The same beat you see, on their side.
Notes on the slides, private to the one who writes them
A note per slide, or one for the whole session
My notes opens beside the slides: a framed note for each slide, a new one as you move on, or one note for the whole session. A participant can also add a note on any slide you have shown, and pin it on the board under its slide.
Draw, write and stick on the board around the slides
The slides sit on a board. Participants draw and highlight with the pen, add text and sticky notes, and arrange them around the slide. A guest has the pen and a few colours; signing in opens more pens, more colours and the board’s files.
You see that notes were taken, never what they say
Notes and drawings stay on the participant’s device. The session only counts them: how many notes, which slides were drawn on. Nothing can reconstruct a note or a stroke.
AI notes, chapter by chapter
When you prepared the deck with Diaposi AI, a signed-in participant on a laptop also gets the notes Diaposi AI wrote, chapter by chapter, as you reach each chapter.
Present the file you already have
PowerPoint, PDF or Word, up to 10 MB. The deck opens as it is, from the browser, on any computer: no add-in, nothing to rebuild.
- PowerPointA .pptx, as you made it
- PDFAny deck exported to PDF, Keynote or Google Slides included
- WordA .docx, opened as slides
Beside the slides: polls, questions, quizzes and surveys on the same deck
What a participant keeps after the session
Signed in: kept in My learning
A participant who signs in keeps the board and the notes in their account, with the slides you showed as a file of that board, grown as you went on. They reopen it from the dashboard, and Diaposi AI can explain a slide, write a quiz or flashcards from it.
A guest: on the device, and still saved later
Without an account, the board and the notes stay on the phone or laptop that took them. Signing in during the session moves them into the account; once the session has ended, the room hands a key that still saves it, for up to a day.
More on the same slides
Each of these runs in the same session, on the deck you uploaded once.
Anonymous questions on the slide in view
Participants ask from the slide they are looking at, anonymously by default, and the room votes the shared questions up.
Anonymous Q&AA poll on any slide
Launch a multiple choice, a rating, a ranking, a free answer or a word cloud on the slide you are on; the results show under it.
Live pollsA survey before they leave
Ratings and free answers at the end of the session, nothing marked.
Live surveyThe session kept as a learning space
A signed-in participant keeps the slides, the board and the notes, and studies them with Diaposi AI.
Augmented learningFor learners, on their own files too
What a participant does in your session, they can do on their own course files: notes, boards, quizzes and mock exams.
For learners
Where slides on phones change the room
Every slide you showed, with the room’s Got it and Review and its questions, is kept in your session report.
Frequently asked questions
How do participants follow my slides on their phones?
They scan the QR code on your screen or type the eight-digit code at diaposi.com, give a first name, and the slide you are on opens in their browser. Nothing to install, no account. On a phone the slide stands on the bottom bar; on a laptop the whole deck is laid out on a board.
Can participants look back at a slide I already showed, or read ahead?
Looking back, always: the slides you have shown stay open, and one tap brings them back to yours. Reading ahead is your choice at the start, Current slide only or Allow upcoming slides, and you can change it live from the cockpit’s settings.
Can participants take notes on the slides?
Yes. My notes gives them a framed note per slide, or one note for the whole session, and they draw, write and stick notes on the board around the slides. The notes stay on their device; you only see how many were taken, never what they say.
Is Diaposi an alternative to PowerPoint Live?
For a room that follows the slides on their own phones, yes. You upload the PowerPoint, PDF or Word file and present it from the browser on any computer, with no add-in; participants open it with a code, scroll back, react and take notes. The polls, questions and quizzes of the same session sit on the same slides.
Does it work with a PDF or a Word document, not only PowerPoint?
Yes. Diaposi takes PowerPoint, PDF and Word files up to 10 MB and shows them slide by slide. A Keynote or Google Slides deck works once exported to PDF.
Is Diaposi free?
Yes. Hosting is free to start, with no card, and participants never pay. The paid plans, Starter and Pro, are for learners.
