About this app

Don't just watch. Take part.

DUIU is a social video platform where every post becomes a thread — and anyone can respond with their own video. Votes decide who rises to the top.

■ Reply to any thread with your own video
■ Vote on what deserves to win
■ Compete for the top rank
■ Follow threads as they grow

You're not scrolling a feed. You're stepping into something already in motion — and your video can take it over.

How it works
Someone posts a video. Others respond. Votes stack up. The best rises. You can see in real time exactly where you stand — and so can everyone else.

Drops — Compete for prizes
Brands launch sponsored threads with real prizes. Submit your video, get votes, and win. The more people join, the bigger the prize pool gets.

Your stage. Your moment.
Whether you want to express an idea, start a challenge, or outcompete everyone in the thread — DUIU gives you a way to show up and stand out.

Anywhere is a stage. Anyone is a star.
