I don't think AI is needed here -- I wrote an Outlook plugin about 15 years ago that used fuzzy diff between messages in the thread that extracted only the new information added by each person and presented it as a message digest or as a labeled people digraph with msg-bubbles. For the life of me I don't understand why this isn't built in to all email clients -- the way gmail especially quotes replied emails, I need to spend time hunting up and down the message trying to recreate the timeline -- even getting the most recent bit seems harder than it should be. Do you use Outlook? -- If there is interest, I can try and resurrect it. Although it's not as necessary as it once was -- not as many "Re: re: FW: re: fw: hello!" messages now that people use Slack and Teams, etc.
