AI-enabled cleanup, on your terms

Make space without the guesswork.

Klyr is an AI-enabled macOS cleaner and private storage analyzer that turns a nearly full drive into a clear, reviewable plan. Find large files, exact duplicates, app leftovers, and Xcode data—then choose what moves to Trash.

See what’s actually taking up space.

Instead of one vague storage total, you get a map of the folders you can inspect. Klyr separates verified duplicates and rebuildable project data from personal files that deserve extra care.
