Important notifications appear here and can be viewed later.

Karui filters out spam notifications and lets you view everything later, even unsent messages.

What it does:

Karui evaluates the notification content privately using your important contacts and calendar info, and decides whether to show it or hide it.

Privacy:

Karui runs privately on your iPhone with Apple Intelligence. It uses an on-device model from Apple, so your private notifications never leave your device. Karui has no server, does not require an account, and sends zero analytics.

Requirements:

Requires an iPhone running iOS 26 or newer and Apple Intelligence enabled.

Limitations:

Tapping a Karui notification opens the original app, but does not jump directly to the message. Just open the original notification for that.
