Doppio

godopp.io

The rendering host for Doppio — live polls, timers and word clouds inside Google Slides.

Doppio is a Google Slides add-on and Chrome extension for live audience participation. A presenter adds a poll, word cloud or timer to a slide; the audience votes from their phones; results render on the slide as it is being presented. This domain serves those charts and the API they run on — it is infrastructure, not the product website.
