Mentimeter vs AhaSlides: which interactive presentation tool is worth paying for?

• How the free plans are limited

  Mentimeter's free plan lets you build as many quizzes and polls as you like but counts participants across your account: 50 per month, with one session a month allowed to exceed it. AhaSlides doesn't limit monthly participants, but each session takes 50 people and each presentation can hold only 5 scored quiz questions and 3 polls.

• Monthly or yearly billing

  AhaSlides sells true monthly plans, though they cost about three times the yearly rate ($23.95 vs $7.95 a month for Essential). Mentimeter bills yearly in most countries; a monthly Basic option appears only in a few markets such as Canada, India, Mexico and Brazil.

• Audience caps by tier

  AhaSlides caps each tier by audience: 100 on Essential, 2,500 on Pro, and 50, 100 or 200 on its education plans. Mentimeter's paid plans allow unlimited participants, with quiz slides limited to 2,000 at once.

• Quiz depth and game feel

  AhaSlides quizzes include pick answer, pick image, type answer, match pairs, correct order and categorise, plus team play and a spinner wheel. Mentimeter's quiz slides offer select-answer and type-answer questions with speed scoring from 500 to 1,000 points and a top-10 leaderboard.

• AI and polish

  Menti AI, which drafts whole presentations and quizzes from a prompt, comes with every Mentimeter plan, and Mentimeter is the more established, polished product. AhaSlides caps AI at 5 queries a month on the free plan and 20 on Essential, adds a ChatGPT app and an MCP server, and some reviewers report lag with large audiences.

As of October 2026 (US prices), AhaSlides Essential costs $7.95/month billed yearly ($95.40) or $23.95 billed monthly for 100 participants, and Pro costs $15.95/month yearly ($191.40) or $49.95 monthly for 2,500; education plans are yearly-only at $2.95, $5.45 and $7.65 a month for 50, 100 and 200 participants. Mentimeter Basic costs $11.99 and Pro $24.99 per presenter per month, billed yearly ($143.88 and $299.88), with education versions at $8.99 and $14.99, and its paid plans don't cap the audience outside quizzes. AhaSlides is cheaper for small and mid-sized groups and is the only one of the two with monthly billing for most buyers; above 100 participants on business plans, Mentimeter Basic ($143.88/year) undercuts AhaSlides Pro ($191.40/year).

• your audiences often exceed 100 people and you don't want tier caps
• you want the free plan to allow full-length quizzes for small groups
• you want AI-drafted presentations on every plan
• you build in Keynote and want to import those decks
• you're comfortable paying yearly for an established tool

• you want to pay month to month, even at a higher rate
• you're a teacher on a tight budget (education plans from $2.95/month)
• you want game-style quizzes with matching, ordering, categorising and team play
• your free sessions stay under 50 people at a time but happen often
• you'd use a spinner wheel or image-answer questions

• you run live, game-show style quizzes and want one simple price: $9/month, billed monthly
• your groups are big — up to 500 players per game
• players should be able to read every question on their own phone (large rooms, hybrid and video calls)
• you don't need homework, self-paced or presentation features

AhaSlides wins on price flexibility and quiz variety: monthly plans, education pricing from $2.95 a month, and quiz formats such as match pairs, correct order and team play. Mentimeter is the stronger pick for large audiences and for occasional small sessions, since its paid plans have no audience cap and its free plan doesn't limit quiz length. If what you really want is a game-show quiz night rather than a deck, Quizzo ($9/month, billed monthly, up to 500 players) is a simpler third option.
