One Swiss Knife in the exact shape of your life.

Decision Maker

Decision Maker, a small reckoner that computes in your browser and stores nothing. No account, no cloud, no telemetry.

Live · runs in your browser · no network

This is not a screenshot. It's the real tool, running right here: go on, put something in it.

Forged into a knife, this tool ages with use: the blades you reach for wear soft, entries you tend keep their bloom, and the years travel with the file through every reforge.

Some decisions deserve a spreadsheet. The rest — which film, whose turn, pizza or curry — deserve a coin with more than two sides. The Decision Maker takes your options and picks one, fair and square, with no memory of past verdicts and no favourites. Democracy for households, at last free of debate.

Standing facts

In ten years

Decision Maker computes; it doesn't hoard. Open the file in 2036 and it will do the same arithmetic it does today, because the arithmetic is written into the file and nothing about it needs a server to agree.

If Offline.Ltd closes tomorrow, nothing on your machine notices. That isn't a marketing promise; it's simply what a file is.

Getting your data out

There is nothing locked in to get out: copy the numbers, or keep the file. Either way you owe no one a request form. No export queue, no "we'll e-mail you a link within 48 hours", no format that only one vendor can read.

Copy the file to a USB stick, a NAS, a folder your devices already sync. It runs on Windows, macOS, Linux, Android and iOS, online or off, because a browser is the only thing it ever needed.

Who else sees this

Nobody. Decision Maker works out its answer in your browser and forgets it the moment you close the tab: there is no store to breach, because nothing is stored. There is no account, no telemetry, no analytics, and no code in the file that opens a network connection, pull the cable and watch it carry on working. How privacy works across the Reckoners tools →

Questions people ask

01

How does the Decision Maker choose?

You give it the options, it picks one at random, and you all agree in advance to abide by the result. The abiding is the hard part; the picking is instant.

02

Is the random pick truly private and offline?

Yes — the whole thing is one HTML file running in your browser, offline. It computes the pick right there, stores nothing, and nothing leaves the page. Not even the pizza-versus-curry deliberations.

03

When is a random decision maker actually useful?

Whenever the options are close enough that arguing costs more than either outcome: choosing a restaurant, assigning a chore, picking who goes first. If you feel disappointed by the result, that is also an answer.
