Four ways to run the room

  • Quiz

    Timed questions, points for speed, a podium at the end.

  • Buzzer

    Teams race to buzz first. You judge, scores update live.

  • Board

    An idea wall. People post notes and photos, like and reply. Translate in one tap.

  • Deck

    Polls, word clouds, ratings and quiz rounds in one running order. One PIN for the whole talk.

How a session runs

  1. Step 1: Build it

    In the editor, or let the AI draft it from a topic.

  2. Step 2: Put it on the projector

    Open the big screen on any browser.

  3. Step 3: People join

    They scan the QR or type the PIN. You drive from your laptop or phone.

Put the live screen in your slides or site

Every screen has an Embed button that copies the code. The frame follows the session live.
