Before I was a brain

DiskSphere

The sphere Doc was born from. A map of your disk: every dot is a file, every colour a folder. See where your disk went — then pick what to clear.

  • A Rust scanner, not a script: your whole disk, fast.
  • Seven 3D shapes, a sunburst, a treemap: the same files, nine maps.
  • Search by name, jump to Finder, trash from inside.
  • Every suggestion tells you why. Fixed rules, no AI, nothing leaves your Mac.
DiskSphere, full sphere view: the whole cloud: every dot is a file.
Full sphere — the whole cloud: every dot is a file.
DiskSphere, sunburst view: the same files as rings.

In plain words

What is Doc the Brain?

Doc is a second brain: a running system that keeps one person's files, ideas and money in one place, drawn as a brain made of glowing points. Alberto, a researcher in Italy, builds it and shows the work on the YouTube channel Doc the Brain.

What is DiskSphere?

DiskSphere is the Mac app Doc was born from. It scans a disk or a folder and draws every file as a point on a 3D sphere, so you can see where your space went. It costs €3, one-time.

What DiskSphere does

  • Scans a whole disk or one folder with a scanner written in Rust.
  • Shows the same files as seven 3D shapes: full sphere, sphere, disk, islands, time, orbit and galaxy.
  • Shows them in 2D too: a sunburst chart and a treemap.
  • Finds a file by name and shows it in Finder.
  • Moves what you choose to the Trash, so you can put it back.
  • “Quick space” lists what could go, by fixed rules on name, size and date. You check every item.
  • Works on your Mac only: no data leaves the computer.

Price and requirements

€3, one-time purchase, no subscription. For macOS 15 or later, Apple silicon and Intel. Notarized by Apple. A Windows version is planned.

Questions

What is DiskSphere?

DiskSphere is a Mac app that scans a disk or a folder and draws every file as a point on a 3D sphere. You see where your space went, find the big folders and move them to the Trash.

How much does DiskSphere cost?

€3, paid once, no subscription. You pay on this site through Stripe and download the app for macOS 15 or later.

Which Macs does it run on?

Macs with Apple silicon and Macs with Intel. The app is notarized by Apple.

Does DiskSphere send my files anywhere?

No. The scan runs on your Mac and no data leaves the computer.

Does DiskSphere delete files?

It moves the items you choose to the Trash. While they are there you can put them back from Finder. It refuses to move system folders, your home folder and its Library.

How is it different from a treemap app?

DiskSphere has a treemap and a sunburst chart too. It adds a 3D view: the same files as a sphere, a disk, islands, a timeline, an orbit or a galaxy.

Is there a Windows version?

Not yet. A Windows version is planned.
