Diaposi vs AhaSlidesEvery slide interactive, free.
Diaposi Session turns your PowerPoint, PDF or Word file into a live session where every slide carries questions, Class Pulse and notes, with polls and quizzes on top, and every participant follows it on their own device. Diaposi is free. There is no paid plan today, and participants never need an account.
The bottom line
Both tools import a PowerPoint or a PDF and add polls, quizzes and questions for an audience on their phones.
In Diaposi every slide of your deck stays interactive, with questions, Class Pulse and notes, and the free account includes exports and each participant's activity in your report, numbered by arrival, never by name.
AhaSlides Free allows 5 quiz and 3 poll questions per presentation, its imported slides take only emoji reactions, and exports and participant reports are on paid plans.

Every slide of your deck stays interactive
Upload your PowerPoint, PDF or Word file, up to 50 MB, and every page keeps its questions, its Class Pulse signals and each participant's private notes. Participants follow the slide you are on, go back to any slide already shown and mark each one Got it or Review.
AhaSlides imports PowerPoint and PDF on every plan, and its documentation says imported slides become content slides that take only emoji reactions.
No 5 plus 3 cap
Run as many polls, quizzes and questions as the session needs. Polls come in six kinds: yes or no, true or false, multiple choice, rating scale, free answer and word cloud; quizzes are built from your own slides, written by you or imported.
AhaSlides Free allows 5 quiz questions and 3 poll questions per presentation.
Exports and every participant's activity, free
When the session ends, your report keeps it slide by slide, exported as PDF or CSV and saved for 12 months after the session. It shows each participant's activity, numbered by arrival, never by name, and each participant can keep a personal report with a free account.
On AhaSlides Free there is no PDF, JPG or Excel export, and a report per participant comes with its Pro, Edu Large and Enterprise plans.
Every participant gets their own copy of your deck
Participants follow the slide you are on and go back to any slide you have shown. On their own copy they draw, highlight and keep notes that stay on their device: you see how many notes were taken, never what they say. One tap under each slide says Got it or Review, and a private Not sure helps them find what to revisit.
They watch their own progress as they go, see how the whole room is doing slide by slide, and the screen stays awake for the whole session. AhaSlides' documentation says imported slides become content slides that take only emoji reactions.
See Diaposi SessionA report on every participant, and a report for each one
Your report lists each participant's activity, numbered by order of arrival, never by name: active time, time in sync with you, Got it and Review, questions, polls answered and notes taken. The most active and the quietest are marked, and the CSV carries the same numbers.
Each participant can keep a report of their own too: with a free account, the session becomes their learning journey, with their marks, the pages to look at again and their notes. On AhaSlides, a participants report comes with the Pro, Edu Large and Enterprise plans.
Everything Diaposi does with the same deck
Diaposi Session is one part of Diaposi, the EdTech platform for interactive and measurable learning. The PowerPoint, PDF or Word file you present can also be followed by learners at their own pace, turned into a mock exam built from the same course files, and measured from one session to the next, all with one free account. Participants never need an account or an app to join.
Present your deck, live
- Your PowerPoint, PDF or Word file as it is; a Word document scrolls like a document
- Six kinds of polls, and quizzes built from your slides, written or imported
- Anonymous questions the room votes up; the one it rallies behind rises onto your screen
- Your ink, laser dot and whiteboard pages appear live on every participant's screen
- Open with the room's expectations, close by asking whether they were met
Follow at every participant's pace
- Participants follow your slide, go back to any slide shown and keep notes you never see
- With a free account: a summary, and a Learn more card on each slide you have reached
- Signed in, each participant keeps the session as their own learning journey
- Learners can also upload your deck and follow it alone, with Quiz me and chapter checks
Practise under exam conditions
- Up to 6 course files become one mock exam, with chapters found in your own documents
- Run it with your class: one clock, private extra time, every paper handed in at its deadline
- Written answers marked criterion by criterion; one that cannot be marked waits for you
- Learners practise alone too: a grade out of 20 and the pages to reread
Measure what was learned
- A report slide by slide after every session, as PDF or CSV
- Quiet signals: the slides participants went back to after you had moved on
- Your lecture evidence: every session in one view, compared with the period before
- Mock exams graded out of 20, by question, by chapter and for each participant
