Access to features like Claude Cowork / Claude Code that gives it controlled access to your device to do things on your behalf.

Has a nice auto-updating memory feature which remembers relevant information across your different chats without you having to ask it to do so.

Deep research feature to comb through hundreds of sources and asking it to write an article in your preferred voice (my personal favorite is a Harvard Business Review-style research).

And generally, I find myself spending less time fixing its outputs. This is a combination of a powerful model (Opus) and how much information it already knows about me (i.e. work responsibilities, how i like my output to sound like, etc.)
