Your messiest folders, sorted tonight.

It runs on your own Mac — nothing uploaded, no account — and files what lands in Downloads and on your Desktop into folders you already keep.

Three things happen.
You do the third.

Every evening, for whatever landed in Downloads and on your Desktop.

01

It reads

A small model runs on your Mac and works out what each file is: an invoice, a boarding pass, an installer you already ran.

02

It suggests

Each file gets a destination you already use, or “safe to bin”, with a one-line reason you can check.

03

You approve

Nothing moves until you say so. Junk waits 30 days in quarantine. Every filing move can be undone.

Your folders. Not new ones.

Every destination it proposes is somewhere you already put things. When a file has no obvious home, it says so and waits — rather than inventing a folder you never asked for and filing into it.

No good home for this oneSo it asks, instead of inventing a folder name
Needs your eye
It reads the folders you already have before it proposes anything, and prefers one of them over a new name.
A file it cannot place goes to Needs your eye with the reason, not into a folder of its own invention.

Tell it once.

When you correct where something goes and say why, Arruma drafts a rule in your words — and keeps it only if you say yes. Next time, that kind of file is suggested where you said.

One correction, one rule

Your fix
Insurance papers go in Personal/HouseDrafted from your reason — keep it?
Your call
Polis 2027.pdf~/Documents/Personal/House
Suggested by your rule
One stray click is not a rule. It drafts one when you give a reason, or fix the same thing twice.
Every rule is a sentence you can read, edit or delete. You can write your own too — where things go, and what it must never touch.
No rule outranks the guards: photos, tax and legal files are never suggested as junk.

It lives in the menu bar.

There is no app to keep open and nothing to check. Arruma reads what landed while you were doing something else, and puts one line up there when it has something to show you.

Tonight’s summary is one click away, and it is three numbers: what it would file, what looks safe to bin, what it wants your eye on.
Open the window only when you want the reasons. Ignore it and nothing happens — the files stay exactly where they landed.
No Dock icon unless a window is open. It is a menu-bar app, which is another way of saying it is small.

Nothing leaves your Mac.

The model runs on your Mac’s own silicon. Turn Wi-Fi off and it works exactly the same. It is downloaded once, during setup, and never needs the network again.

Nothing gets deleted.

Junk goes to quarantine, where it sits for 30 days. Not the Bin — a folder Arruma keeps, with the file whole and one click to put it back.

Tax, legal, ID and credential files are never suggested as junk.
Personal photos are never suggested as junk either.
Every filing move is written down before it happens, so it can be undone.

Questions.

Does it read my files?

Yes, on your Mac. It opens enough of each file to tell an invoice from an installer, and what it reads never leaves the machine.

Does it need the internet?

Once, to download the model during setup — Arruma says what it is and how big before it starts. After that it never needs a connection again — turn Wi-Fi off and it works the same.

What if it gets one wrong?

You see the reason before anything moves, and you can say no. Filing moves are recorded and undoable; junk sits in quarantine for 30 days. Tell it why, and it offers to remember.

What about photos, tax and legal files?

Never suggested as junk. That guard sits above every other rule, including the ones you write yourself.

Arruma isn’t finished yet.

There’s no waitlist and nothing to sign up for. When it’s ready to use, the download will be on this page.
