About Immersia
Immersia is a real-time slide and media sync tool built for anyone who shows something to a group in person. A guide, presenter, or host controls slides from their device — every guest sees the same image, video, or visual at the same moment on their own phone.
No app download for guests. They scan a QR code and join instantly in their browser. It works on any modern phone or tablet.
What we believe
The best live experiences happen when everyone is on the same page — literally. When a guide shares a historical photograph, every guest should see it clearly. When a presenter reveals a key chart, the back row should see it as sharply as the front. The technology should be invisible — the story, the art, the data, the moment should be what people remember.
The product
- Live slide control. The host swipes on their device — every guest screen updates instantly. No delay, no buffering, no desync.
- QR code join. Guests point their camera at the code and they're in. No app store, no download, no account, no login.
- Progressive Web App. Immersia runs as a PWA — installable to the home screen, works offline, loads fast, never needs updating.
- Works on any device. iPhones, Android phones, and tablets all see the same content at the same time.
- Free to start. A free plan with 1 tour or event, 50 slides, and 10 MB of media. Paid plans start at $99/month.
