Show the right ad to the right person. Automatically.
A small device that attaches to any screen you already own. It reads who's standing in front of it — age and gender — and instantly plays the ad that fits. No new screens. No integration.
The product
Purplelight AI is a compact sensor bar that clips to the top of any display.
It turns a screen that plays the same loop all day into one that responds to whoever is actually watching.
Fits any screen
Clips to the top edge of any display and connects over HDMI. Nothing about your existing setup has to change.
Understands the moment
Age bracket, gender and whether someone is actually looking — measured on the device, in real time.
Pays for itself
The same screen, the same footfall, far more relevant advertising. Higher yield per second of screen time.
How it works
Three steps. No integration.
Attach
Clip the device to the top of your screen and plug it in. Installation takes under ten minutes.
Detect
The on-device camera estimates the age bracket and gender of whoever is in front of the screen. Nothing leaves the device.
Serve
The ad best matched to that viewer plays instantly. The screen keeps adapting as the audience changes.
See it live
Watch the ad change with the audience.
Illustrative. The device never identifies a person — it only estimates an age bracket and gender, on-device.

Privacy
Anonymous by design.
- Processed on the device
- Video never leaves the sensor. There is no cloud upload.
- No faces stored
- Frames are analysed and discarded in memory. Nothing is written to disk.
- No identity, ever
- The device cannot recognise a returning person. It has no concept of who you are.
- Aggregate reporting only
- You get counts by age bracket and gender. Never an individual record.
Built to be explained in one sentence to anyone who asks.
