Read unsent messages: when someone takes a message back, it’s still in Karui. Takes about a minute to set up. Every app’s notifications in one searchable history. Your VIP contacts always get through your Focus, from any app. Wake Me: people you choose can ring an alarm in an emergency, even when your iPhone is silenced. Spam and promotions are silenced, judged by the actual message, not the app. One-time codes are never silenced. Several quick messages from one person arrive as one notification. Auto Reply: tells your VIPs you’re driving, in a meeting, or asleep, and that you’ll reply later. Automatically translate notifications into your language. Deadline reminders: when a notification asks for something by a certain day, Karui reminds you the day before. How it works: Karui evaluates notifications privately on your iPhone, using your important contacts and calendar info, and decides whether to show them or hide them. Setup: you add the Karui Shortcut from a link, which takes about a minute and is all you need to read unsent messages. To filter spam, you also choose a Focus that keeps your other apps quiet. Karui guides you through both. Spam filtering and deadline reminders require Apple Intelligence to be supported and turned on. Viewing unsent messages works without it. Privacy: Karui runs privately on your iPhone with Apple Intelligence, using Apple’s on-device model, so your notifications stay on your device. The optional Second Opinion feature, off by default, sends a notification’s text to Apple’s Private Cloud Compute when you turn it on. Karui has no server, does not require an account, and sends zero analytics.
