Interactive presentation FAQ
Is it really free?
Yes. You can build in the editor with no account, and a free Quack account lets you save unlimited decks and present live to up to 300 people, no card required.
Do I need to sign up to try it?
No. The editor opens straight away and lets you build up to three slides. You only create an account when you want to save or present. Your work carries over.
How is this different from PowerPoint or Google Slides?
Your slides are interactive: drop in live quizzes, polls, word clouds and Q&A, and the audience responds from their phones in real time, with no add-ins and no extra app.
How does the audience join?
They scan a QR code or type a 6-digit PIN in any phone browser: no app, no account for participants.
Can I mix content slides with interactive ones?
Yes. One deck holds title and content slides alongside quizzes, polls, scales, word clouds and Q&A; arrange them however your session flows.
