One Swiss Knife in the exact shape of your life.

Kitchen Scaler

Kitchen Scaler, 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.

The recipe serves four; you are feeding eleven, one of whom eats like three. The Kitchen Scaler multiplies a recipe up or down and gives you the adjusted quantities, so every ingredient scales together and nothing is left at the original amount out of spite. It computes and forgets — your grandmother's recipe stays exactly where it belongs.

Standing facts

In ten years

Kitchen Scaler 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. Kitchen Scaler 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 do I scale a recipe from 4 servings to a different number?

Tell it the original servings and the servings you need, and it works out each ingredient's new quantity. The whole recipe moves together, which is where hand-scaling usually goes wrong.

02

Do I have to upload my recipes to use it?

No, and you cannot — it stores nothing at all. It is one HTML file running offline in your browser; you type quantities, it computes, and everything vanishes when you are done. The family recipes remain a family matter.

03

Can it scale a recipe down as well as up?

Yes — halving for two is the same arithmetic as tripling for a party, and it does both without complaint. Whether a quarter of an egg is achievable remains between you and the egg.
