Kosmica

Your visual library. Private. Native. Everywhere you are.

Download for Mac Get it on iPhone

Tap any image.

One library, two devices.

Add on your Mac, find it on your iPhone a moment later. Everything syncs through a private iCloud container, and Handoff picks up where you left off.

Made of glass.

Toolbars, tab bars and controls use Liquid Glass on macOS 26 and iOS 26, so your images stay in front and the chrome steps back.

Finds what you mean.

Kosmica reads your library on device. Search in plain words, by colour, or by what something looks like.

Links are first-class.

Save a URL and Kosmica keeps a snapshot of the page, a summary of what it is, and how often you go back to it.

Share a collection.

Invite people to a collection with CloudKit sharing. They add, you see it; you rename, they see it. No sign-up, no link to a website.

Yours.

Your files live in your iCloud. There is no Kosmica account and no Kosmica server. The analysis runs on your devices, and nothing leaves them unless you share it.

On iPhone, set a storage cap for originals and Kosmica keeps the thumbnails while iCloud holds the rest.
