Each app’s page has its requirements, its price where it has one, and its download where it is released.

DiskCells

Coming soon · not released yet

A disk cleaner for the Mac, with an AI agent that runs on your Mac.

DiskCells shows what fills your disk, tells you what each big item is, and frees space safely. Everything runs on your Mac, with its AI in your own local Ollama.

What it does

  • See what fills your disk: A clear picture of your whole disk, by category and down to every folder, measured the way your disk really counts space.
  • Our own indexing engine: An indexing engine we built in-house keeps your disk mapped in the background, so questions about size are answered at once, without scanning again. It stays on your Mac.
  • Just ask: Ask in plain English or simple French, like “show me what is bigger than 5 GB”, and get exact answers you can act on in one click.
  • Safe by design: It knows what can go and what must stay, explains every suggestion in plain words, and never touches your personal libraries or macOS itself.
  • You stay in control: Nothing is removed without your confirmation, and everything goes to the Trash first, so you can put it back.

What stays on your Mac

  • Its own code talks only to the AI on your Mac (the video player library it bundles has not been audited yet).
  • No account and no telemetry.
  • The AI sees names, sizes and dates, plus a short text snippet for folders it cannot recognise; all on your Mac.
  • What it learns about your disk stays in the app’s own folder, readable by your account only.

Before it ships

  • Not released yet: no download and no price.
  • AI answers need Ollama and a small local model on your Mac; size searches work without them.
  • macOS 15 or later on Apple silicon, with Full Disk Access. The interface is in English for now.
  • The first scan of a large disk can take a few minutes.
  • The clean-up commands have so far run only on test folders, not on real disks.
