How it works
From an empty room to a synchronized crowd in three steps.
Create your event
Set it up in minutes — name, schedule, venue, and a cover image. No technical setup required.
Design the screens
Build colors, media, polls and interactive modes in the studio and assign them to your event.
Go live
Share one link. The crowd joins from their browser and you drive every screen in real time.
Five ways to light up the room
Switch live modes on the fly. Each one turns the crowd into a different kind of show.
Story
A swipeable reel attendees explore — with likes, comments, polls and Spotlight.
Manual
Push a color, gradient or media to every screen at once, live from the control room.
Auto
A pre-programmed sequence of steps with timing and looping that runs itself.
Gyro
Device tilt maps to color zones — one phone can drive all, or each reacts on its own.
Ambient
Your microphone's frequencies drive the colors of the room in real time.
+ Intro & Outro
Warm the crowd up before the show and send them off after — with reels that play in the before and after phases automatically.
Everything you need to run the room
No app required
Attendees join from a single link in their browser. Nothing to download or install.
Live engagement
Polls, likes, comments, and attendee Spotlight submissions — all flowing in real time.
Branded links
From a simple link to a custom subdomain or your own domain, depending on your plan.
Geofencing
Optionally require attendees to be physically near the venue to join the experience.
Co-organizers
Invite teammates to help run an event, with granular permissions for each person.
Notifications
Keep followers in the loop with reminders and announcements before and during events.
Built for every kind of crowd
Concerts, festivals, nightlife, sports, weddings and more — if there's a crowd with phones, there's a moment to choreograph.
