Live polls and word clouds that build on screen as people answer.
Menti is the presentation-shaped version of live polling: you build slides, the audience votes from a code on their phones, and the bar chart or word cloud grows in front of everyone. Question types cover scales, rankings, open text and competitive quizzes. The free plan lets you build as many presentations as you like but will only engage 50 participants in a rolling month before it blocks presenting.
AltFTool does this too
If you would rather not leave the site, Poll Maker covers the same job here — free, no account, and it runs in your browser.
Open Poll MakerQuestions
A genuinely usable free tier with paid plans for volume or team features. Free accounts can engage only 50 participants per rolling month before presenting is cut off.
Yes. Mentimeter sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
