Honestly, the integration into office is an excellent idea. I've been using chatgpt to work on documents, letting it write entirely new sections for me based on my loose notes and existing text. Which for now I have to either paste in or feed as a pdf through a plugin. But the 25USD I paid I literally earned in a single day through the time saved vs the hours I was justified to bill.

Once I have that integrated into word directly it'll be huge.

People also seem to expect llms to just do all the work. But that's not my experience, for generative text anyway. You have to have a solid idea of what you want and how you want it. But the time the llm saves on formulation and organisation of your thoughts is incredible.
