Our verdict on Diaposi

Diaposi adds live interaction and audience feedback to existing presentations. It is designed for educators, trainers, workshop facilitators, meeting leaders, and conference presenters who want participation without requiring attendees to create accounts or install an app. Presenters can upload PPT, PPTX, PDF, DOC, and DOCX files, then add polls, quizzes, anonymous questions, reactions, drawing, annotation, laser pointing, and whiteboarding. Participants join in a browser through a QR code or session code.

The Free plan is the central strength. It includes no participant cap and no question quota, along with browser-based participation, live polls, quizzes, questions, reactions, drawing, and reports. The analytics layer goes beyond basic response collection: presenters receive slide-level analytics, heatmaps, engagement metrics, presenter reports, participant reports, and participant recaps. PDF and CSV export support makes the resulting session information easier to review or share. AI-assisted question generation adds another preparation option for live quizzes.

Diaposi is a strong fit for presenters who prioritize detailed engagement evidence and a broad set of live activities without a participant limit. Its narrowest area is ecosystem fit: the platform is web-based, and the listed integration is Mistral AI. That makes it less suitable for teams choosing software around a wider native app or integration ecosystem. Presenters who already work with common office and presentation files can add interactivity without replacing those materials, while users seeking extensive platform coverage or deeper integrations should consider alternatives. Overall, Diaposi favors flexible browser participation, rich audience signals, and reporting over a broad software ecosystem.
