Visualize every file, uncover hidden clutter, and safely reclaim space with AI.
No account. No license key. No catch.
Features
Disk Clean AI scans your whole drive on your Mac, then groups what it finds into things you can actually act on. Every screenshot below is the real app.
Explore
The whole tree, drawn for you. Click any slice, rectangle or bubble to focus on it, colour by file type, folder or age, and read the details in the inspector on the right. Anything you select can be revealed in Finder, previewed with Quick Look, or added to the cleanup queue.
Rings radiating out from the focused folder.
Find
Four searches under one roof, each hunting a different kind of clutter. Duplicates are matched by size, a partial hash, then a full SHA-256 — so a match is a byte-for-byte copy. Similar photos are grouped by a perceptual hash, with the best copy marked Keep. Every result has a + to stage it for review.
Every file over 10 MB, largest first.
Apps
Every installed app with its size, version and the last time you opened it. Each one lists the caches, logs and support files it keeps in your Library — so you can uninstall the whole thing, or just sweep the leftovers.
Quick wins
The moment a scan finishes, the sidebar surfaces the usual suspects — with totals. Click one and Explore jumps straight to those folders so you can see exactly what you'd get back.
AI Advisor
Add an OpenRouter key, pick any model, and the advisor reviews your biggest files, well-known cache folders, old downloads, unused apps and duplicate groups. It explains what's safe to remove and why, with a confidence level on every suggestion.
Review & Clean
Everything you stage lands here first, grouped by where it came from. Items from your Library or system folders are flagged for a second look; the rest are marked Safe. Tick what goes, hit Clean, and it all goes to the Trash — never straight to oblivion.
The startup disk, an external drive, your home folder, ~/Library, or any folder you pick.
The OS, frameworks, keychains, Mail, Photos and anything inside a package can never be queued.
Preview any file with Quick Look before deciding, or jump straight to it in Finder.
Each cleanup is one batch. Changed your mind? Undo puts every item back where it was.
Daylight, Midnight, Graphite, Nord, Solar, Dusk, Ocean, Forest, Sakura — or follow the system.
Nothing leaves your Mac except the AI request you choose to send and an anonymous check for updates.
How it works
Point it at a drive or folder. The scan runs entirely on your Mac — nothing is uploaded, and a full startup disk takes about a minute.
Add your OpenRouter key and pick a model. It reads names, sizes and dates — never file contents — and explains what's safe to remove and why.
Tick what goes, skip what stays, hit Clean. Everything lands in the Trash, so you can still change your mind.
Bring your own key
Disk Clean AI never proxies or resells AI credits. Paste an OpenRouter key, choose any model it supports — Claude, GPT, Gemini, Llama — and pay OpenRouter directly. A typical scan costs a few cents.
Settings · AI provider
Open source
Disk Clean AI is MIT-licensed and completely free. There’s no trial, no subscription and no license key. An app that can delete your files should be one you can read, so all of it is public.
The code that scans your disk, decides what's safe, and moves files to the Trash is all public. So is exactly what gets sent to the AI.
Clone the repo, open it in Xcode 16 and hit Run. No account, no license key, no server you have to trust.

FAQ
Yes. It's open source under the MIT license, with no trial, subscription, account or license key. Download the latest release or build it from source. The only thing that can cost money is the optional AI Advisor, which runs on your own OpenRouter key.
On GitHub at github.com/postmcp/diskcleanai. The SwiftUI app and this website are both in the repo. Clone it, open macApp/DiskCleanAI.xcodeproj in Xcode 16 or later, and run the DiskCleanAI scheme.
Open an issue for bugs or feature ideas, or send a pull request. New Quick Win rules, safety-policy fixes, translations and Explore patterns are all welcome. The contributing guide in the repo explains how to get set up.
Yes, but only what OpenRouter charges. Disk Clean AI does not mark up or resell model usage — a typical scan costs a few cents on your own OpenRouter key.
No. Nothing leaves your disk until you review a list and approve it. Approved items go to the Trash, so you can still get them back.
File paths, names, sizes, types and dates — enough to reason about what's clutter. It never reads file contents and never uploads files.
Anything OpenRouter offers: Claude, GPT, Gemini, Llama, Mistral and more. Use a cheap model for everyday scans and a stronger one when you want more careful judgement.
The app checks for new versions once a day and installs them in place after verifying a checksum. You can also check manually from the Disk Clean AI menu, or grab any build from the GitHub releases page.
macOS 14 Sonoma or later, on both Apple silicon and Intel.
