I feel that software like this, which has the same functionality as the web version rather than leveraging the client's advantages to do things the web cannot, is not very meaningful
First thing I tried to find on that webpage is whether I can run Gemma models on the app with inference on-device. Apparently you can't.
As long as installing web apps to desktop with real app UX sucks horribly, we will remain needing this.
It's about app-ifying the desktop. Instead of opening a browser, then remembering that you have a bookmark and clicking it or googling the site you are looking for, the idea is to have a step less and just click something on your desktop or taskbar (like on a mobile device)
