Live audience engagement

Know what the room thinks — and who said it

Cairn puts polls, quizzes, word clouds, ratings and Q&A on every phone in the room with a code or a QR scan. No app, no account. Unlike the usual slide add-ons, it carries your branding and tells you who answered what.

Live votes, split by table

The presenter opens a poll, votes arrive from the room and the bars grow. The presenter then switches the results to a table-by-table comparison.
