Nijia
Nijia helps Mac users understand disk usage and review cleanup decisions. Its five modules cover Smart Cleanup, Space Analysis, Dev Workspaces, AI Desk Tidy, and System Watch. Developers can inspect repositories, Git worktrees, build artifacts, and caches with workspace context. File organization is proposed for review. Storage checks and organization proposals run locally on the Mac without an external AI account or API key. Selected cleanup actions require review and confirmation before moving files to Trash; emptying Trash has a separate confirmation. Nijia is paid software with monthly, annual, and one-time Pro licences, each supporting up to two Macs.

ByteSweep
ByteSweep is a storage cleanup and file-management suite for computers and phones. Its Mac and Windows desktop apps scan disk use, explain what is taking up space, and let users review cleanup suggestions before removing temporary files, logs, Trash contents, update leftovers, app remnants, and caches. Tools also identify exact duplicates and similar photos or videos, organize selected folders, locate files from plain-language descriptions, and show developer-related storage such as Xcode and Docker files. A basic view explains storage in plain language, while an advanced view exposes more detail. Supported desktop cleanups can be restored for seven days. Separate iPhone and Android apps help users review photos, large videos, screenshots, and duplicate contacts; phone features and purchasing are separate from the computer license.

Diskfern
Diskfern is a native macOS utility for analyzing storage and reviewing files for cleanup. It scans a Mac’s startup disk, home folder, selected folders, and connected drives, then organizes accessible files in treemap, list, and sunburst views. Users can compare folder sizes, search indexed file names with natural-language queries, apply filters, and use Smart Highlights to locate common storage such as developer caches, logs, downloads, and application data. File inspection provides size, location, permissions, safety labels, and Quick Look previews. Pro and Family add a review-based cleanup Collector, app removal, and one-click staging of selected items before they are moved to Trash. Disk Advisor can explain scan findings using Apple’s on-device language model on supported Macs. Diskfern is designed for Mac users who want to understand local disk usage and decide what to remove; scanning and storage analysis run on the Mac.
