Of course you can use the native UI of all the apps in your ecosystem, the biggest feature of Hermes for me personally is that I can run any task in any of my 30 or so self hosted tools from a single chat interface (matrix), which is also quite secure. No longer do I need 30 open tabs and lots of clicking around, one sentence in my favorite chat app (even on the go in the phone), and many tasks can be executed at once. Unification of control.
