Decka

Decka turns your Microsoft PowerPoint slides into a two-way conversation. Drop an interactive activity straight onto a slide and your audience joins in seconds from any phone or laptop. Your audience doesn't need to create an account or install an app. Responses appear live, right where you're presenting.

Run the activities that keep a room awake:

• Drawings & games — break the ice and make the moment memorable.
• Live polls — take the pulse of the room and show results the instant votes land.
• Word clouds — turn open-ended answers into a picture the whole room shapes together.
• Quizzes — add scoring, speed, and a leaderboard to any topic.
• Q&A — collect and surface audience questions without breaking your flow.
• A/B tests — surprise your audience with a reveal that different participants saw different options, and illustrate behavioral effects like anchoring.

Made for anyone who presents live: all hands hosts who want to energize the room, educators who need real participation, sales and marketing teams energizing pitches and webinars, team leads running all-hands and workshops, and event hosts who want a room full of energy instead of silence.
