Quick answer
Mentimeter is an audience response and engagement add-on: presenters build live polls, quizzes, word clouds, and Q&A slides, often alongside a separate deck built in PowerPoint or Google Slides. Prezi is a full presentation platform that turns the material you already have, or a class described in a sentence, into a deck with checks for understanding built in: polls, word clouds, quizzes, and deck-grounded audience Q&A, inside the same presentation. Teams that only need to bolt interactive slides onto an existing deck typically choose Mentimeter. Teams that want one on-brand deck with checks for understanding already built in typically choose Prezi.
What is Mentimeter?
Mentimeter is an interactive presentation and audience response platform built around live polling, quizzes, word clouds, and Q&A. Presenters create "Mentis," share a join code or link, and participants respond in real time from their own device. Menti AI can generate slides or full decks from a prompt, and Mentimeter supports importing existing PowerPoint, Keynote, or Google Slides and embedding Mentimeter's interactive slides into those tools.
Mentimeter's plans include:
- Free, with 50 participants per month and 23 slide types
- Basic, around $11.99 per presenter/month billed yearly, adding unlimited participants, presentation import, and result exports
- Pro, around $24.99 per presenter/month billed yearly, adding branded themes, workspace collaboration, Q&A moderation, Mentimote remote control, and Quick Forms
- Enterprise, with SSO, SCIM, LMS integrations (Canvas, Blackboard, Moodle, D2L Brightspace), and workspace-level insights
Paid plans support up to 200 slides per presentation and up to 10,000 participants (2,000 for quiz-type slides), plus integrations with PowerPoint, Zoom, and Microsoft Teams.
Mentimeter's strength is depth of engagement question types (word clouds, scales, open-ended, Quick Forms, segmentation of results) layered on top of a presentation, rather than the presentation itself.
What is Prezi?
Prezi is an interactive presentation platform that turns the material you already have into experiences where people participate, apply ideas, and show what they understand. Bring the slides you already have, in PowerPoint, Word, or PDF, and Your Designer redesigns them within your team's brand rules, so a deck comes out on-brand automatically instead of requiring manual formatting. Or start from a sentence describing what you're covering and Prezi builds the deck from there. (See the full Prezi vs. PowerPoint comparison if you're weighing a switch from a slide-based tool, or the Canva vs. Prezi comparison if design-first templates are your starting point instead.) The canvas lets a presenter teach it in the order the room needs, moving between ideas and focusing in on details, rather than clicking through a flat, sequential slide deck.
Prezi's live presenting experience builds checks for understanding directly into the deck itself:
- Live polls and word clouds, collected in real time with no separate tool needed
- Auto-generated quizzes based on the presentation's own content, editable before you run them
- "Explain this to me," a deck-grounded AI Q&A feature that answers audience questions using what is actually in the presentation, rather than a generic model answer (for a deeper look at how this stacks up against another AI-native design tool, see Prezi vs. Claude Design)
- Audience Q&A that collects questions before, during, and after a session, with audience upvoting and a moderation queue so presenters control which questions surface
- QR-code joining, so attendees participate from their own phone with no app to download and no login
- A live audience view so viewers can follow along on their own devices, whether they're in the room or remote
- Camera mode, a camera-based presenting mode for a more personal, broadcast-style delivery
- Presenter mode with notes, camera mode, and a dedicated presenter header
- Results by question and an end-of-session feedback digest, so you can see what landed after the fact
- Narrated video export for sharing the presentation asynchronously
- Mobile creation, for building a full presentation end-to-end from a phone
Because these checks live inside the same file as the deck, presenters do not need to maintain a separate polling tool, import their slides into it, and keep the two in sync. Prezi was named a G2 Leader for Fall 2026 across three categories: Audience Response, AI Presentation Tools, and Presentation Software. More than 170 million presenters have built over 500 million presentations with Prezi, reaching more than 180 million people.

Where each tool wins
Choose Mentimeter if you already have a deck workflow you like (PowerPoint, Keynote, Google Slides) and mainly want to bolt on richer audience response question types, larger participant volumes, or LMS/enterprise integrations for a big organization.
Choose Prezi if you want the deck itself, its design, and its checks for understanding to come from one workflow: import existing content or describe your class in a sentence, get an automatically on-brand redesign, and present with polls, quizzes, word clouds, and grounded Q&A already built in, with no separate tool to import into or keep in sync.
Frequently asked questions
Is Mentimeter a presentation tool or a polling tool? Mentimeter started as an audience response and polling tool and has expanded into slide creation with Menti AI. Its core strength remains the range of interactive question types (polls, quizzes, word clouds, Q&A, Quick Forms) rather than full deck design and branding.
Does Prezi have live polls and Q&A like Mentimeter? Yes. Prezi includes native live polls, word clouds, auto-generated quizzes, and "Explain this to me," a deck-grounded Q&A feature that answers audience questions using the presentation's own content, along with async question collection and audience upvoting.
Can Prezi replace Mentimeter for audience response? Partly. For most live presentation use cases, including polls, quizzes, word clouds, and audience Q&A, Prezi covers much of the same ground as Mentimeter without a separate tool. Organizations that specifically need Mentimeter's deeper question types (Quick Forms, response segmentation) or LMS integrations at enterprise scale may still want Mentimeter alongside their existing deck tool.
What does Prezi do that Mentimeter does not? Prezi redesigns imported PowerPoint, Word, or PDF content to match a team's brand guidelines automatically through Your Designer, or builds a deck from a sentence describing your class, and its Q&A is grounded specifically in the presentation's content. Menti AI focuses on generating new slides or Mentis from a prompt rather than redesigning an existing deck to match brand rules.
Which tool is better for sales and business presentations? Prezi is generally the stronger fit for business use cases such as sales decks and client pitches, since it combines brand-consistent deck creation with checks for understanding, results by question, and a G2 Leader track record in a single workflow. Mentimeter is a strong fit when the priority is layering structured audience feedback and Q&A onto a deck a team already maintains elsewhere. For a look at how Prezi stacks up against another audience-response-focused option, see Kahoot vs Prezi: Which Presentation Tool to Use in 2026.
Bottom line
Mentimeter and Prezi both support live polls, quizzes, word clouds, and Q&A, but they solve different problems. Mentimeter is an audience response layer that presenters add to a deck. Prezi turns the material you already have, or a class you describe in a sentence, into a deck with that same interaction built in natively, plus results by question, async and upvoted Q&A, and a G2 Leader standing across three categories in Fall 2026, with more than 170 million presenters having built over 500 million presentations reaching more than 180 million people. Teams that want a single on-brand deck with checks for understanding already inside it get more value from Prezi's consolidated workflow; teams that want to keep their existing deck tool and add a dedicated polling and quiz layer get more value from Mentimeter.
