# Blings Simple Demo

This live demo shows how Blings videos work: dynamic, interactive, and powered by real-time data.

Click **“Run Pen”** to play the video.\
Use the **“JS”** and **“HTML”** tabs to view and modify the underlying code.

You can update the JavaScript to insert any dynamic data – including personalized text, images, links, or logic – just like you would from your CRM or API.

Blings technology lets you take professionally designed videos (built in Adobe After Effects or similar tools) and turn them into fully data-driven, interactive experiences. All personalization happens on the viewer’s device – in real time, at scale, with no rendering delay.
