Crumb is a privacy-first, AI-powered storage cleaner that lives in your menu bar. It performs a read-only audit of your entire Mac — including System Data, Time Machine local snapshots, Docker.raw, iOS backups, and cross-user usage — surfacing hidden space hogs that home-folder cleaners miss.
Key Features
- Whole-Mac Audit — Safe, read-only scan across the entire disk, not just your home folder. Includes a cross-user leaderboard to see which account is consuming the most space.
- Ask Crumb AI — Ask in plain English whether a file or folder is safe to delete. The AI explains what it is, whether it regenerates, and what might break — then proposes a reviewable plan. Nothing happens until you approve it.
- Reclaim by Category — Tally and clean build artifacts, Xcode data, caches, and package caches with a single click after reviewing the breakdown.
- Power Tools — Find and remove duplicate files, uninstall apps along with every leftover, and tidy messy folders by file type.
- Private & Local — File contents never leave your device. No account, no sign-up, no cloud. Apple-notarized and Developer ID signed.
- Reversible — Every action can be reviewed and undone, so you stay in control.
Pricing
- Free — Whole-Mac read-only audit, System Data breakdown, and one full cleanup.
- Pro — $9 one-time purchase. Unlocks Uninstall, Duplicates, Organize, Ask Crumb AI, cross-user view, and unlimited cleanups. Up to 2 Macs. No subscription.
Requires macOS 12+ (Monterey). Works on Apple Silicon and Intel.
