Using Kepter

Stacks: things that belong together

Checked against macOS 26 · August 2026

A stack is a group of similar things. Some stacks Kepter builds for you. Some you make yourself. Either way a stack is a way of looking at what you already have, not a place things get moved to.

The Stacks tab, then one stack opened.

The ones that make themselves

Kepter groups what your documents are: Receipts, Statements, Letters, Forms, Tickets, Passes, Cards. These appear as soon as you have one of them, and they use the same words as the filter chips, so a thing is filed the same way whether you browse by kind or by stack.

Two other kinds have to earn their place. A subject, or a company whose name keeps turning up, becomes a stack only after it has appeared three times. That is deliberate: it is why you get Receipts and one or two familiar names instead of hundreds of groups you never asked for.

Company names get said the way you would say them. Legal suffixes drop away and an acronym-led name collapses to the acronym, so “HMS Commercial Service, Inc.” becomes simply HMS, and different spellings of the same company end up together.

Kepter never claims to know a company. The only signal is that something recurs in your documents.

The ones you make

When you want particular things together, make a stack and put them there. Open the Stacks tab and choose New Stack, or right-click anything and choose Add to Stack. Name it whatever you would call it out loud: Tax 2027, House, Car.

You can select several things first and add them in one go.

Renaming

Rename any stack, including one Kepter built. The rename is a label over the top: Kepter keeps feeding the stack exactly as before, and it wears your word from then on. Call Statements “Bills” and it keeps filling itself.

What a stack can do

Nothing moves

Adding something to a stack does not move, copy, or rename the file on your Mac. A stack records which things belong to it and nothing else, so your folders are exactly as you left them. Delete a stack and the files are untouched.
