Getting started

Doppio turns a Google Slides deck into a live, interactive room. Your audience votes from their phones and the results fill in right on your slide. This guide takes you from a fresh install to your first live poll.

Sign up and install

There is no Doppio account to create. Doppio works with the Google account you already present with, so signing in is the whole sign-up.

You will need two small installs: the Slides add-on, where you build your polls, and the Chrome extension, which runs the show when you present.

1. Install the add-on

1. Open any deck in Google Slides.
2. Go to Extensions → Add-ons → Get add-ons and search for Doppio.
3. Click Install and approve the permissions.

Once installed, Doppio lives under Extensions → Doppio in every deck.

Working in a managed Workspace?

If your organisation locks down add-ons, an admin needs to approve Doppio once for everyone. Point them at the Doppio listing in the Google Workspace Marketplace.

2. Install the Chrome extension

The extension starts and stops your live sessions, so install it on the machine you present from.

1. Find Doppio on the Chrome Web Store and click Add to Chrome.
2. Click the Doppio icon in your toolbar and choose Sign in with Google.
3. Use the same Google account you use for Slides.

That is the lot. The add-on, the extension and your analytics dashboard all recognise you through the same Google sign-in.

Create your first event

An event is your deck's connection to Doppio. It holds your polls, your theme, and the code your audience uses to join. One deck, one event.

1. Open your deck and choose Extensions → Doppio to open the sidebar.
2. You will see Let's get started.... Give your presentation a name. The name appears in your results reports; your audience never sees it.
3. (Optional) Open the Default Theme section to pick a colour palette and chart background now. Every poll in this deck will start from these defaults, and you can change them at any time. See Branding & themes.
4. Click Next.

Doppio creates your event and hands you two things:

• A 5-digit event code. Your audience types this at doppio.us to join. The code belongs to this deck for good, so you can reuse the same presentation week after week.
• A QR code. It points straight at your event, no typing required. Use Copy QR Code or Download QR Code and pop it onto your opening slide or your handouts.

One code covers the whole deck

Every poll in a presentation shares the same event code and QR. Your audience scans once at the start, and their phones follow your slides from then on.

Create your first poll

Polls live on slides. Move to the slide where you want one, or add a fresh slide, and open the Doppio sidebar.

1. The sidebar shows No Poll Here.... Click Create a New Poll.
2. Write your question. Keep it short enough to read from the back of the room.
3. Add your answers. You need at least two options and can have up to ten. Drag the handle on any answer card to reorder, and use the colour swatch to give each option its own bar colour.
4. Tune the Audience Settings. Set how long voting stays open (30 seconds by default), how many votes each person gets, whether results fill in live or hold for a reveal, and where the countdown appears. Every setting is explained in Polls & settings.
5. Click Save Poll.

Doppio places a preview of your chart onto the slide. Size and position it like any other image. When you present, the live chart takes its place and the bars fill as the votes come in.

Keep it punchy

Two to four options read best on a big screen, and voters decide faster.

Present it

1. Open your deck in Chrome and click the Doppio extension icon.
2. Click Start Presentation, then present your deck exactly as you normally would, speaker notes and all.
3. Your audience scans the QR, or visits doppio.us and types your 5-digit code. No apps, no accounts, no fuss.
4. When you reach a poll slide, voting opens on their phones and your chart fills in live.
5. When you are done, click Stop Presentation. Your results are saved and waiting in the dashboard.

You and your audience, side by slide.
