AI-assisted storage analysis for macOS

DiskSage — disk analyzer and cleaner for macOS

Find what is taking up space on your Mac. DiskSage analyzes the drive or folder you choose to find large files, re-creatable caches, developer build data, apps, archives, and media. Review the results with optional AI guidance, then move only the items you select and confirm to the Trash.

A clearer storage picture

Find large files, caches, and developer build data.

DiskSage separates informative storage measurement from cleanup recommendations, so a large file is never treated as disposable just because it is large.

Analyze a location you choose

Select a drive or folder. DiskSage measures accessible data locally and safely skips macOS-protected areas.

See more than caches

Review developer build data, applications, archives, installers, media, documents, and other large files.

Understand every recommendation

Optional AI assistance classifies candidates as Safe, Review, or Keep and explains the reasoning in plain language.

You decide what moves

Nothing is deleted automatically. Only items you select and confirm are moved to the macOS Trash.

How it works

How to analyze and clean up disk space on your Mac.

Choose a location

Select the drive or folder you want DiskSage to analyze. Inaccessible and macOS-protected areas are skipped.

Choose what to review

Select result types and detection sensitivity. Sensitivity changes size and age thresholds, not deletion safety.

Review the evidence

Inspect sizes, categories, dates, and optional Safe, Review, or Keep AI guidance. Search and sort the available results.

Move selected items to Trash

Confirm your selection before cleanup. Items remain recoverable from the Trash until you empty it.

Optional AI, explicit consent

Your files are not the prompt.

DiskSage scans locally. AI features send an item name and limited metadata through the Z-Tech Labs service only after you consent. File contents and full disk paths are never sent. You can withdraw consent in Settings without losing local analysis.
