What is your most effective classroom activity using a word cloud?

I’m exploring practical ways teachers use word clouds for student reflection, formative assessment, reading responses, classroom community, and writing revision.

I’ve been working on a word cloud tool called wordcloud.art, which lets users create customizable and animated word clouds. Before developing more education-focused templates, I’d love to learn from teachers: What age group or subject do you teach? What classroom activities have you used word clouds for? What features would make a word cloud tool genuinely useful for you and your students? I’m especially interested in examples that go beyond simply displaying vocabulary words.
