Measure

Instant analytics

Engagement score, heatmap and full report the second you end.

Built for the session. Designed for the room.

Any presentation becomes a two-way conversation: fast to start, calm to run, measurable the moment it ends.

What does the host see during a live session?

Designed to change nothing in how you present, only to add a layer

Ask the room mid-session, in about ten seconds

What stays the same

Your session, exactly as it was

  • Your deck, untouchedThe .pptx or .pdf you already present with, same slides, same order. Nothing to rebuild.
  • Your way of presentingFull-screen slides, arrow keys, your own rhythm. The controls fade out when you don't need them.
  • The equipment in the roomA browser and the projector already there. No install, no new hardware to procure.
  • No accounts to manageYour audience joins with a code or a QR. Nothing to enrol, nothing to administrate.

What the layer adds

Everything you could not see before

  • A live read of the roomGot it and Review on every slide, with a slow-down alert when too many fall behind.
  • Questions that sort themselvesAsked anonymously, up-voted by the room, so the one everyone is stuck on rises to the top.
  • Ink that reaches every screenAnnotate the slide and stream it live, laser pointer included, without leaving your deck.
  • A report the moment you endEngagement score, slide-by-slide heatmap, PDF and CSV, with no personal data collected.

Drawing and whiteboards

And a blank board when the slide runs out of room

The pen works on any slide, and when a slide is the wrong place for it, one button inserts a whiteboard as a real slide straight after the one you are on. The room sees it, you draw on it, and it turns up in the report like every other slide. Five colours, two highlighters, three stroke widths, text, arrows and lines, an eraser, undo and clear. The last button decides whether the room watches your ink land on their own screens.

Everything in the session is quantified, and all of it is saved to your report

Every reaction, question, vote, revisit and second spent on a slide is counted while you present and written into the report the moment you end the session. Nothing to assemble afterwards: it is already there, in three forms.

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.

On their phone

Their own read on the session, while it is still running

We do not only quantify the session, we hand it back

The moment the session ends, everyone in the room gets a full report of their own. Not a score, but the session as they lived it, slide by slide, ready to go back over tonight.
