The interactive presentation platform built around your audience.

Diaposi turns any slide deck into a two-way, real-time conversation. Reactions, questions, polls and live drawing let you see exactly what your audience understands, so every presentation is audience-centric, not one-directional.

The tool that finally connects teachers & students

Real feedback, not guesswork. In every domain, at every level.

For teachers

Know what landed, while you can still act

Live reactions and questions become a 0–100 score and a slide heatmap the moment you end.

For students

A voice, without the spotlight

Join in seconds and stay anonymous: react, vote, take private notes, and ask what a raised hand never dares.

A layer on the deck you already have, live in under 30 seconds

Bring your own deck

Upload the .pptx or .pdf you already teach with. Nothing to rebuild, no new workflow.

Students join in seconds

A QR or a six-character code, on any phone, tablet or laptop. No account, no install.

The room answers back

React, raise a hand, vote in polls, draw together, and keep private notes tied to each slide.

See what actually landed

A live engagement score while you teach, and a private slide-by-slide report the moment you end.

A live Diaposi student session on a phone: the current slide, the Got it and Review reactions, per-slide progress and upvoted class questions

Private notes, tied to the slide

People write while it is still fresh, on the slide it belongs to. Nobody else sees a note, and every one of them comes back in their end-of-session report.

Backprop ≠ gradient descent. One computes the gradient, the other uses it.

Slide 614:19

ReLU over sigmoid: no vanishing gradient. Ask why in the tutorial.

Frequently Asked Questions

Everything you need to know about Diaposi — how it works, what you get, and how your data is handled.

Yes. Upload a deck and run a live session without a credit card or a contract. For a whole department or institution, write to us and we'll set it up with you.

Yes, including from the host. There are no student accounts and no emails: everyone appears as Student 1, 2, 3, on the presenter's screen as well as in the report. Reactions, votes, questions and notes never carry a name, so nobody — host included — can trace an answer back to a person.

Yes, and they stay private. Notes are written on the slide they belong to, nobody else can see them, and every note comes back in the student's end-of-session report.

The .pptx or .pdf you already teach with. Same slides, same order, nothing to rebuild and no new workflow to learn.

An instant report: a 0–100 engagement score, a slide-by-slide heatmap, the top questions and per-slide breakdowns, exportable as PDF or CSV.

Nothing is lost. A dropped host connection never ends a session: the room, the current slide and everything already collected stay exactly where they were, and reopening the session puts you back in control. Students who reconnect are resynced to the live slide with their reactions intact. Only pressing “End session” ends a session.

Any browser on any phone, tablet or laptop. Nothing to install on either side, and students join with a QR or a six-character code.

Yes, by design. Diaposi collects no accounts, no emails, no cookies, no tracking and no student records, so there is nothing to leak and nothing to consent to. Privacy is a property of the product, not a setting you have to switch on.
