"Let's Compare" is a unique web app I created for a client's YouTube channel, inspired by "Watch Data." Rather than producing traditional videos, she needed an innovative solution. To meet her requirements, I developed a custom theme that mimics the video style of "Watch Data" and transformed it into an interactive web app. Through this app, the client effortlessly fills out a form with video data, and the app dynamically generates captivating video-like content, complete with animations and transitions, right in the browser. Additionally, I integrated a thumbnail generation function, allowing her to create eye-catching thumbnails that perfectly match the video's theme.
