A calmer way to clean
- Kai lives in a calm sea. Its home shows what is ready to clean at a glance; sail out to the open sea and the photos Kai found drift up in a few bundles you can net — or read them as a simple list.
- Kai finds what's safe to clear — exact duplicates, similar photos and videos, old screenshots and large files — and explains why each item is suggested.
- Screenshots are sorted by what is in them — one-time codes, tickets, receipts — so expired codes and used tickets come up first, and receipts and documents are never swept up.
- Everything happens on your device. No photos or content are ever uploaded, and no face recognition.
- Beyond photos, Kai clears file clutter — pick folders in iCloud Drive or On My iPhone and it finds large, old, duplicate and temporary files you can safely remove. It also merges duplicate contacts, keeping a backup so any change can be undone.
- On Mac: see where your disk space went, then clear developer junk, duplicates and forgotten files — everything moves to the Trash, restorable anytime.
- You review and decide before anything is removed; nothing is auto-deleted, on any platform.
Unfold it, and the sea opens up
On iPhone Duo, Kai's sea and the open water spread across the larger screen.
