Which vendor offers real-time audience engagement features?

Hi G2 community, I’ve noticed that presentations can fall flat if the audience isn’t actively involved. Polls, Q&A, live reactions, or even quick quizzes can make a huge difference. I’m looking for presentation tools that make this easy to set up and run in real time.

Here are a few solutions I’ve been exploring:

• Mentimeter (4.7/5 on G2, 650 reviews): Designed for interactivity, with polls, quizzes, and word clouds. It’s great for workshops and meetings, but how well does it scale for enterprise-level events with thousands of participants?
• Microsoft PowerPoint (4.6/5 on G2, 4,251 reviews): Offers Q&A and live reactions when used inside Teams. It’s familiar and widely adopted, but is this enough to compete with purpose-built interactive platforms?
• Google Workspace (4.6/5 on G2, 43,609 reviews): Includes a simple audience Q&A feature for live sessions. It’s seamless for quick collaboration, but is it powerful enough to handle real-time engagement at scale?

For those of you who run live presentations:

• Which of these tools has delivered the strongest real-time engagement?
• Do these features meaningfully boost participation, or do they just add extra steps?
• Any surprises (good or bad) when scaling interactive sessions across bigger audiences?

Thanks for sharing!
