DiskNebula turns your storage into a living treemap, then uses private on-device AI to explain what is taking up space, what is likely safe to remove, and where to start cleaning up.
One-time purchase macOS 26+ Apple Silicon No account required
Visualization
The explorer combines the treemap on the left with the detail panel on the right so you can spot the biggest folders, inspect them quickly, and reclaim storage without guesswork.
Features
A complete picture of your disk in seconds, with the tools to understand what matters and clean up safely.
Your storage rendered as a cosmic treemap. Bigger regions mean bigger storage costs, so the cleanup opportunities are obvious immediately.
Ask plain-English questions about any folder. The AI can run fully on your Mac using downloadable local models, with no account, tracking, or mandatory cloud API.
Analyzes your storage to help you visually expose forgotten caches, large directories, node_modules, and other hidden space hogs.
Every file goes to the macOS Trash first, never permanently erased. If you change your mind, you can restore it from the app’s undo flow.
Parallel file-system scanning with a live progress feed. A 500 GB drive is fully mapped in seconds, not minutes.
No telemetry, no analytics, no cloud sync. Your file paths and sizes never leave your machine — not even to check for updates.
The app supports both local and remote AI modes. Use it to understand large folders, review likely cleanup candidates, and reclaim your space with more context than Finder gives you.
DiskNebula gives you a faster way to understand storage, spot cleanup candidates, and clear space on Apple Silicon Macs running macOS 26 or later.
