I don’t really see why anyone would use this unless they’ve been in a coma for the past few months and never heard of ChatGPT.
I'm not sure if this is what is planned of course, but that would be far more widely used than an otherwise siloed website you have to visit specifically.
Also remember that most people have at least never used ChatGPT, and most probably still haven't heard of it. We live in a tech bubble – none of my family had heard of it a few weeks ago. They all use Google search on a daily basis.
