ChatGPT added a table of contents to long conversations. The ChatGPT account and Greg Brockman both announced it, and the way they described it will sound familiar to anyone who lives in the tool: for every conversation that started as "one quick thing" and became a full-on saga, the table of contents is here. It's live now for any chat with five or more responses.
What it actually does is give you a clickable outline of the thread. Instead of scrolling up through forty messages to find the version of the email you liked three exchanges ago, you click the outline and land on it. The thing you've been treating as one endless scroll now has a spine you can navigate by.
That's a small change with an outsized effect on how you work in long threads. Most real work in ChatGPT is a back-and-forth where you draft something, refine it, change your mind, and circle back. The deeper that thread gets, the more the good stuff sinks out of reach. An outline pulls it back to the surface.
If you use ChatGPT for anything that runs long — a report you're shaping over an afternoon, a tricky email you keep rewriting, a planning session that sprawls across dozens of messages — you've lost time hunting for an earlier answer you know is in there somewhere. This kills that hunt. You don't have to change how you prompt or learn anything new. The next time a "quick question" turns into a marathon thread, look for the outline and click straight to the part you need.
