Slido vs Mentimeter: Honest 2026 Comparison

The short answer

Slido is better for Q&A and large-scale audience interaction. Mentimeter is better for visual results and interactive presentation design. Both free plans cap the audience, Slido at 100 participants and three polls per event and Mentimeter at 50 participants a month, so regular use means a paid plan. If cost is a constraint, both have capable free alternatives.

Prices and plan limits here were checked against each company's own pricing and help pages in September 2026. Both have evolved significantly in recent years as Slido was acquired by Cisco (integrated into Webex) and Mentimeter expanded its feature set well beyond polling.

Slido in 2026

Slido's core strength is Q&A moderation at scale. The audience upvoting feature — where attendees vote on questions submitted by others — is uniquely useful at large conferences where the challenge is surfacing the best questions from hundreds of submissions. The integration with Cisco Webex means it works smoothly in enterprise environments that already use Webex.

The free Basic plan allows up to 100 participants, basic Q&A, and three polls per event; anything beyond that requires a paid plan. Slido sells plans per event, from $60, or per year, from $210 for business, and doesn't offer monthly billing, which makes it a bigger commitment for individual presenters or small organizations.

Mentimeter in 2026

Mentimeter has expanded to a full interactive presentation platform. Beyond polling, it now includes presentation slide building, live collaboration features, and an extensive template library. The visual quality of results displays remains the best in the category. Word clouds, animated charts, and image-based polls all work smoothly.

The free plan includes unlimited presentations and almost every question type, but it stops at 50 participants a month, and exporting results is a paid feature. Paid plans are billed yearly, from $14 per presenter a month, and the education plans for teachers and students start at $11.

When to choose rifts.to instead

For presenters and organizers whose primary need is anonymous live polling without the cost or complexity of either platform, rifts.to covers the core use case for free. If you need neither Slido's Q&A moderation nor Mentimeter's visual design — just a reliable way to collect live responses and display results — it's the simplest starting point.
