I use projects for working on different documents - articles, research, scripts, etc. And would absolutely love to write it paragraph after paragraph with the help of ChatGPT for phrasing and using the project knowledge. Or using voice mode - i.e. on a walk "Hey, where did we finish that document - let's continue. Read the last two paragraphs to me... Okay, I want to elaborate on ...".
I feel like AI agents for coding are advancing at a breakneck speed, but assistance in writing is still limited to copy-pasting.
