Questions before you go live?
Everything you need to know before running your first Diaposi session.
No. Upload the material you already use — PPT, PPTX, PDF, DOC or DOCX — and Diaposi builds the live layer around it.
No. They join from any browser using a QR code or session code. No account, installation or roster is required.
They can react, answer polls and quizzes, ask and upvote questions, take private notes, draw on slides and follow the presentation from their own device.
Yes, by default. Participants can ask, react and answer without attaching their identity.
Diaposi brings questions, reactions, poll and quiz responses, participation and quieter signals such as look-backs and pacing into the presenter cockpit while the session is still running.
They are signals nobody has to deliberately send — for example, participants going back to an earlier slide or still working on material after the presenter has moved on.
Diaposi turns the session into a slide-by-slide report showing participation, questions, reactions, results, pacing and the moments that may deserve another look.
Yes. Participants can leave with a personal recap containing their notes, responses, flagged material and relevant session content.
AI is optional. It can understand your material and prepare poll or quiz drafts before the session, but the presenter reviews everything before it reaches the audience.
The session continues normally. Uploads, live participation, drawing, questions and reporting do not depend on the AI layer.
Yes. Diaposi is designed for education, training, workshops, meetings and conferences.
Diaposi is built and hosted in Europe with privacy-first choices such as no participant accounts and anonymous participation by default.
