Notification summaries coming in iOS 18.1
Notification summaries are an optional Apple Intelligence feature in iOS 18.1. When turned on, your notifications will be infused with AI for providing more informative content.
For example, with email notifications, you’ll get a summary of the full email contents rather than just an excerpt of the first couple lines.
I love using notification summaries for the Messages and Mail apps especially. Apple Intelligence provides the key information I want better than the non-summarized notifications do.
But I just discovered another very handy use case: summaries for Apple Card spending.
