Now you can "branch" conversations in ChatGPT - start a separate conversation without getting off track in the original.

Here's how:

1. Hover on a message
2. Click "More actions"
3. Select "Branch in new chat"

It's only available in the web interface, not the desktop or mobile app. I can't get it to work so maybe it's still rolling out. Seems like a helpful feature so you don't have to copy and paste something to start a new chat with it.
