My wife and I both have a habit of sending multiple small messages rather than a large one. Probably because we both used IRC extensively on the past and grew up on length-limited SMSes. The summaries are very very handy at letting me glance at my notification's and see if anything in her last x messages needs a reply now or whether it’s just “chat”.
I’ve found LLM summaries of stuff in general to be one of the handiest uses of it personally.
[guillotine raises]
They could have merged the last few recent short messages into one bigger notification, instead of making the notification for the very last message cover the rest.
A bit notable: the AI summarization of spam texts makes them seem much more credible.
There probably should be.
I get the sense that making group chats silent by default would have a more useful impact on notification overload than AI summaries.
