Why does a one page static site that is a few paragraphs of text use 9.3MB of resources (4MB compressed)? Why is the tiny logo in the corner 1MB? It's absurd, especially when you say your pain point with competitors is them being slow and clunky. This could be a 5KB website with internal analytics.
It's not a great look, especially when you're plugging the design studio, collab partner, and founder for such a basic project. If it takes this much resources to make a box of text with a copy button, I would hate to see the efficiency of your larger projects.
Aside from that, congrats on making something. It's simple, looks relatively polished, and works decent. I think you could maintain the simplicity and add a few features to allow generating alternate text, and a variable number of paragraphs that can be copied at once.
