A workshop of builders

Værksted

ᚹᚨᚱᚲᛊᛏᛖᛞ

We build AI-native apps, built on principle.

Værksted is Danish for workshop. The apps we make share an infrastructure, a naming tradition rooted in Old Norse, and a spectrum borrowed from the Bifröst — the rainbow bridge Heimdal guards, one hue per app. And the principles below — written down because we mean them, not because the brand book required a values page.

Principles
01

Privacy by default

Your work is yours. We don't read it, sell it, or train on it. The data stays where it belongs.

02

We sell software, not you

Our money comes from people buying our products, not from selling access to you. No ads, no trackers, no data brokerage.

03

Simplicity over surface area

One craft, done well. If a feature doesn't earn its place, it doesn't ship. We resist the feature factory.

04

Design is how it works

Looks matter. Craft matters more. The interface, the latency, the recovery from failure — every detail, or none of them.

05

No addictive patterns

No infinite scrolls, no manipulated streaks, no engagement metrics dressed up as care. Tools you can put down.

06

No lock-in

Your data is yours, in formats you can read. Leave whenever you want. We earn loyalty; we don't trap it.

The workshop's output

The bard. Notes and knowledge capture, in the tradition of the Norse skalds who carried a people's memory in verse.

Saga

The storyteller. A text editor for long-form writing — where ideas become narratives that hold together.

Sindre

The smith. A product management agent, named for the legendary dwarven craftsman who forged Mjölnir, Gungnir, and Draupnir.
