Slido vs Mentimeter: Which Audience Engagement Tool is Better in 2026?

Overview

Slido and Mentimeter are two of the most widely recognized audience engagement platforms on the market today. Slido, founded in 2012 and acquired by Cisco in 2021, is deeply integrated with Webex and focuses heavily on Q&A and polling for corporate meetings and large conferences. Mentimeter, founded in 2014 in Sweden, has carved out a strong niche in education and interactive presentations, offering beautiful slide-based polls and quizzes that presenters build directly in the browser.

Both tools serve the same fundamental purpose: replacing passive audiences with active participants. But they approach this goal from different angles. Slido excels as a lightweight overlay that works alongside existing slide decks (PowerPoint, Google Slides, Keynote), while Mentimeter is a complete presentation platform where polls and slides are built together in a single canvas. This fundamental architectural difference shapes nearly every aspect of the user experience.

In this comparison, we examine Slido and Mentimeter across features, pricing, ease of use, polling capabilities, anonymous Q&A, and interactive features to help you decide which platform is right for your meetings, classrooms, and events in 2026.

Feature Comparison

Pricing

Slido offers a generous free plan that supports up to 100 participants with unlimited polls and Q&A. Paid plans start at around $12 per month for the Engage plan, which removes the participant cap and adds moderation features. The Enterprise plan includes SSO, advanced analytics, and dedicated support. Slido's pricing is event-oriented, making it affordable for large town halls.

Mentimeter's free plan limits you to 50 participants per presentation and 5 quizzes. The Pro plan costs around $18.99 per month and removes the participant cap, adds unlimited quizzes, and includes all question types. The Pro+ plan at $38.99 per month adds collaboration features, team sharing, and priority support. Mentimeter charges per presenter, which can become expensive for organizations with many users.

Both platforms have moved toward annual billing to reduce costs, but for large teams, either tool can become a significant expense. Neither offers a truly unlimited free tier for unlimited audiences, which is a pain point MeetingTok directly addresses.

Ease of Use

Slido is extremely easy to set up if you already have a PowerPoint or Google Slides deck. You install the Slido add-in, create polls within the sidebar, and your audience participates via slido.com using the event code. For presenters who want minimal friction, Slido's approach is ideal. Mentimeter requires you to build your presentation from scratch in their web editor. While the editor is intuitive and modern, it means you cannot simply reuse an existing slide deck. Learning Mentimeter's interface takes an hour or two, whereas Slido can be learned in minutes. However, once comfortable, Mentimeter users often prefer the all-in-one experience.

Polls

Slido supports multiple choice, rating, open text, and word cloud polls. Polls are created inside the Slido web app or PowerPoint sidebar and are displayed as overlays on your presentation slides. Results update in real time and can be displayed as bar charts, pie charts, or word clouds. Slido's polling is straightforward but limited in question type variety compared to Mentimeter.

Mentimeter offers a richer polling experience with multiple choice, scales (Likert), ranking, 100-point distribution, open-ended, and even Q&A slides. The visual design of Mentimeter polls is more polished, with animated transitions and customizable color themes. Presenters can also create "quiz competition" slides where participants compete on leaderboards. For educators running formative assessments, Mentimeter's polling variety is a clear advantage.

Anonymous Q&A

Anonymous Q&A is Slido's standout feature. It was built specifically for this purpose and remains the most mature implementation in the market. Audiences can submit questions anonymously, upvote others' questions, and moderators can approve, reject, or mark questions as answered. The integration with Webex makes it seamless for Cisco shop environments. Slido's Q&A also supports topic tagging and question threading for large conferences.

Mentimeter introduced Q&A slides as a relatively recent addition. While functional, the Q&A experience in Mentimeter does not match Slido's depth. You can collect questions and upvote them, but moderation and organization features are less developed. For events where Q&A is the primary engagement mechanism, Slido is the stronger choice.

Interactive Features

Slido focuses on a curated set of features: polls, Q&A, word clouds, and idea brainstorming. It does not offer quizzes, lucky draws, countdown timers, or spinner wheels. This intentional minimalism keeps Slido focused but limits its versatility for event organizers who want gamification elements.

Mentimeter adds quiz competitions with scoring and leaderboards, which are excellent for training sessions and classrooms. However, Mentimeter also lacks lucky draws, countdown timers, random name pickers, and spinner wheels. Neither platform offers the full suite of interactive features that modern event hosts expect. Tools like MeetingTok fill this gap by combining polls, Q&A, quizzes, lucky draws, countdowns, and word clouds into a single platform.

Pros & Cons

Who Should Choose Slido

Choose Slido if you run corporate meetings, all-hands town halls, or large conferences where Q&A is the primary interaction mechanism. If you already have PowerPoint or Google Slides decks and simply want to add polling and Q&A as an overlay, Slido is the fastest and most reliable option. Slido is also the better choice for organizations already invested in the Cisco Webex ecosystem.

Who Should Choose Mentimeter

Choose Mentimeter if you are an educator, trainer, or presenter who enjoys building visually rich, interactive presentations from scratch. If quizzes, formative assessment, and audience-paced slides are important to your workflow, Mentimeter's quiz competition and diverse poll types make it superior. Mentimeter is also a strong choice for team workshops and brainstorming sessions where visual engagement matters.
