Karui

Silence spam notifications. See messages people unsend.

Apple’s Focus modes, made smarter.

Requires iOS 27 or later and an iPhone that supports Apple Intelligence, which Karui uses to filter notifications privately. Free, with no in-app purchases, subscription, or sign up.

Also:

Auto-replies to your VIPs in Messages, WhatsApp, LINE, and Messenger while you’re driving, asleep, or busy
Lets your VIPs through your Focus, from any app
Judges spam by the message, not the app it came from
Lets one-time codes through
Combines quick messages from one person into one notification
Keeps every app’s notifications in one searchable history
Translates notifications into your language

Privacy:

By default, Karui runs entirely on your iPhone, with no server and no analytics. If you turn on Second Opinion, some notifications are checked by Apple’s Private Cloud Compute. Details.

My hanko

In Japan, people stamp a personal seal like this in red where others would sign on important documents. This one reads ガ⁠ル⁠シ⁠ア, “Garcia” in katakana, the script Japanese uses for foreign names. It’s just for this site, not a registered seal.
