I use ChatGPT as a long-term research and writing workspace. Some of my conversations are hundreds of messages long and function like notebooks, not just chats.
Right now, long conversations become very hard to reuse: scrolling is painful, search is weak.
What is missing is not better AI, but better text ergonomics.
I strongly suggest adding annotation layers on chat messages, similar to what we have in PDF readers or note-taking apps:
- Highlight any part of any message (mine or the assistant’s)
- Add margin notes or comments on selected text
- Add colored tags or labels (e.g. “important”, “todo”, “check later”)
These annotations would not modify the text itself, only add a personal overlay.
This would transform a chat from a linear timeline into a knowledge workspace (we need visual and semantic anchors inside conversations).
I believe this would massively improve retention, reduce repeated questions, and turn ChatGPT into a true thinking and writing environment, not just a conversational interface.
