Slido vs Mentimeter: which one to pick (and when neither fits)

Slido and Mentimeter are the two best-known tools for getting an audience to answer live. They overlap a lot, so the choice comes down to what your session is built around.

Pick Slido when the questions matter most: town halls, all-hands and conferences where hundreds of people ask and upvote, often inside a PowerPoint or Google Slides deck you already have. Pick Mentimeter when the slides matter most and you want results, like a word cloud, building on the big screen. If you run workshops or trainings on a video call and want people to answer without leaving it, neither is a great fit; there's more on that below.

We make Claryoo, which comes up at the end. The Slido and Mentimeter facts here come from their own pricing pages, checked on 13 October 2026.

How they differ

Slido: built for questions

Slido started as a Q&A tool and it shows. People join with a code, link or QR code without signing up, ask questions anonymously or with their name, and upvote the ones they want answered. On the Professional plan and above, you can review questions before anyone sees them, which matters for a CEO town hall.

Polls, quizzes, word clouds and surveys are all there too. Slido doesn't ask you to rebuild your presentation: it adds polls and Q&A into PowerPoint and Google Slides, and has a Zoom app on every plan.

Mentimeter: built for the presentation

Mentimeter is a presentation tool first. You build the deck in Mentimeter, or import slides on a paid plan, and mix in interactive slides: multiple choice, word clouds, quizzes, scales, open text and Q&A. The audience goes to menti.com, types the code and answers, and results appear live on the slide you're sharing.

The strength is how visible the interaction is. A word cloud growing on the big screen is a real moment in a talk or lecture.

Free plans compared

For one larger event a month, Slido's free plan goes further: 100 people in a single session. For many small sessions with a short poll each, it's closer, but Mentimeter's monthly cap of 50 runs out after a couple of workshops.

Paid plans compared

Both bill yearly. Slido's prices were shown to us in euros, so check slido.com/pricing for your currency; Mentimeter's are per presenter, see mentimeter.com/plans.

Slido limits participants per event by plan, so a bigger audience means a bigger plan. Mentimeter's paid plans have no participant cap. If your audiences are large and you mainly need polls, Mentimeter Basic usually costs less. If you need moderated Q&A for a big event, compare Slido Professional with Mentimeter Pro.

Which is better for...

What about Kahoot?

People often compare Kahoot with both. Kahoot is a game: players join with a PIN and race the clock for points and a spot on the podium. Pick it when competition and energy are the goal, like team events and classroom review. It's less suited to gathering opinions or questions. See Claryoo vs Kahoot.

When neither fits

Slido and Mentimeter both ask people to open a second screen, go to a site and type a code. In a big room, that's fine. On a video call, it's where people get stuck or drift off, and in a workshop the poll results are only half of what you need afterward.

That's the gap Claryoo is built for. It's an AI co-host that joins your Zoom, Google Meet or Microsoft Teams call as a participant.

Claryoo isn't the right pick for everything. It has no word clouds and isn't a slide-design tool, and for a 2,000-person town hall Q&A, Slido is the better fit.

Claryoo has a free plan with 2 session hours a month; Starter $19 a month for 8 hours; Pro $39 a month for 25 hours. You pay for session hours, not seats, and participants never pay. Every account starts with a 14-day Pro trial, no card. Compare in detail: Claryoo vs Slido and Claryoo vs Mentimeter.
