The short answer

Mentimeter suits teachers and facilitators who want a whole presentation built around polls, quizzes and word clouds. Slido suits meeting and event hosts whose main need is live Q&A with upvoting and moderation inside PowerPoint, Google Slides, Teams, Zoom or Webex. The biggest difference is focus: interactive slides versus audience questions.

Mentimeter or Slido: our take

Both tools let an audience join from a phone with a code and respond live, with results on screen and optional anonymity. They share most question types: polls, word clouds, quizzes and open questions. Where they differ is emphasis. Mentimeter is a presentation tool whose slides are interactive, with rankings and scales, the ability to import existing slides, and an AI feature called Menti Creator that drafts a whole interactive presentation from a prompt; AI grouping also sorts open-ended answers. Slido's strongest feature is Q&A: the most-voted questions rise to the top and moderators can review questions before they appear. It also offers surveys, post-event analytics and AI suggestions for poll wording.

Integrations favour slightly different setups. Mentimeter works alongside PowerPoint, Google Slides, Teams and Zoom. Slido, owned by Cisco and part of Webex, plugs directly into PowerPoint, Google Slides, Teams, Zoom and Webex, so polls can sit inside an existing deck or call. Mentimeter has more slide-design options, though neither replaces a full deck tool, and Slido is less playful for game-style classroom quizzes.

Both have free plans with tight limits. Mentimeter's free plan allows 50 participants per month, and its Basic plan removes the participant cap. Slido's free plan covers core features with participant and poll limits, and it sells one-time event plans, annual business plans and education plans from €15/month billed annually, plus enterprise contracts. Both run in the browser.

Pick Mentimeter for lectures, workshops and classes where the session itself is built from interactive slides. Pick Slido for all-hands, town halls and conferences where audience questions matter most, or if your organisation already runs on Webex or Teams.

What is Mentimeter?

Mentimeter builds presentations around audience participation. Slides can be live polls, word clouds, quizzes, rankings, scales or open questions, and people respond from their phones using a code, with results appearing on screen in real time and anonymously if you choose. It is widely used in classrooms, lectures, workshops, all-hands meetings and conferences, and it can import existing slides or work alongside PowerPoint, Google Slides, Teams and Zoom. An AI feature, Menti Creator, drafts interactive presentations from a prompt, and AI grouping helps sort open-ended answers. A free plan lets you try it with a monthly participant cap, while paid plans for individuals, education and teams remove limits and add features like branding and exporting results. It runs in the browser. It's not a replacement for a full slide design tool, and the participant limits on the free plan are tight for larger groups.

What is Slido?

Slido is an audience interaction tool owned by Cisco and now part of Webex. Participants join from a phone or laptop with an event code, then ask and upvote questions, answer live polls, add to word clouds, take quizzes or submit ideas, while the host shows results on screen. Its strongest feature is live Q&A: the most-voted questions rise to the top, moderators can review questions before they appear, and people can stay anonymous. Slido works on its own in the browser, and it plugs directly into PowerPoint, Google Slides, Microsoft Teams, Zoom and Webex, so polls can sit inside an existing deck or call. It also offers surveys, analytics after the event, and AI suggestions for poll wording. There is a free plan with the core features and participant limits, plus one-time event plans, annual business plans, education plans and enterprise contracts. It's built for meetings, all-hands and conferences more than for game-style classroom quizzes.
