AI workflow automation

An interactive demo of the Trello-to-AI workflow

One Trello card asked for something that would show — not tell — how a Danish company can hand work to an AI colleague. The answer was cases.grn.dk: a self-contained interactive page where the visitor types a task, watches an AI pick it up, gets asked a question, answers it, and sees the finished card land at the top of Done. The brief, the domain, the design, the copy, the sound and the publication were all handled by the AI setup the page describes.

ERP / open-source business systems

There is a world outside Microsoft ERP: one Danish wholesaler's order, run on an open stack

Udenfor (“Outside”) follows one order through one day at Nordvind Foods, a fictional Aarhus wholesaler with 14 staff and a web shop — on an open stack instead of Business Central. It plays in three acts: the camera zooms out of the Microsoft walled garden onto a live system map where an order agent, an open-source ERP core on Postgres, the warehouse scanner, GLS, NemHandel/Peppol e-invoicing, a PSD2 bank feed and the tax export light up in turn while the ledger posts itself; then you ask the books a question in plain Danish and watch the SQL and the answer appear; then you change a business rule in one sentence and see it tested and deployed in seconds, next to the 26-day partner change-request timeline it replaces.

Web design / Drupal

Redesigning grn.dk in the open: eight directions, one pick, a live theme switch

The site you are reading redesigned itself with the same card-driven AI pipeline it writes about. Eight complete design directions were built as static previews from the site's real content — real articles, real cases, both languages — and published side by side on demo.grn.dk. One won. It then became a brand-new Drupal 11 theme, built in phases on the live site behind a logged-in preview, and switched on with a single config change.

AI governance / data protection

An AI control layer cast in glass: watch personal data become tokens mid-flight

Kontrollaget (“the control layer”) makes invisible AI infrastructure visible. It is a three-act demo for Danish organisations, in Danish and English: write a prompt containing personal data and watch it fly as tokens through a glass pipeline — PII scanner, policy gate, model router — with every step writing itself into an audit log; relive a US provider’s shutdown day with and without a control layer in place; then try to beat the anonymiser yourself in a live redaction playground.

Accounting automation / UK practices

One client’s month runs itself: bank feed to a filed VAT return, while you watch

AutoLedger is a guided walkthrough for UK accounting practices: one fictional client (Hazelbrook Coffee Roasters Ltd), one month, and a play button. The bank feed lands, every transaction is categorised with its VAT treatment, the ledger reconciles, the nine-box MTD VAT return fills itself in and goes to HMRC, and the reports draw themselves — while an activity log narrates what the engine is doing and why. Nothing leaves the browser; the client, the bank and the filing are all simulated.

AI receptionist / small-business automation

An AI receptionist that never misses a call — with the back office on screen

Frontdesk 24/7 is an AI receptionist for a fictional Danish plumbing firm, Nordlys VVS, that you talk to the way a customer would — by voice or text, in opening hours or after them. The point of the demo is the split screen: while the receptionist answers on the left, the back office animates on the right — the calendar books itself, the caller lands in the CRM, a confirmation SMS goes out and the owner gets a message. Nothing is described; everything is shown happening.

Retail — point of sale

One till, many sellers: a market POS that splits every sale by stall

A point-of-sale system for a physical market where dozens of independent sellers share the same tills. A cashier rings up one basket; the system knows which stall every item belongs to, splits the sale per seller at the moment it happens, and keeps the books each stall settles against. Thai-first interface with a synchronized English translation set, built on Laravel 12 with a Filament v4 admin panel and PostgreSQL underneath.

3D on the web / product presentation

A crystal hall rendered live in the browser — then profiled until it ran everywhere

Kristallsaal is a walk-through jewellery hall that runs entirely in the browser: six vitrines of cut-crystal pieces under museum lighting, a mirror-polished floor, and light that actually splits into colour inside the stones. There is no engine download and no build pipeline — one HTML file, one JavaScript module and Three.js, served as static files. It exists to answer a client question with a demo instead of a slide: what does "3D product presentation on the web" feel like at the high end?

AI content automation

This site writes its own articles — every morning, with a hand-sketched infographic

The articles on this site are written by a pipeline: every morning it scouts what changed in the web-development and AI world, picks one topic worth a practitioner's attention, writes the piece, draws a sketch-style infographic for it, and publishes — 138 articles since mid-April 2026, one per day, without a stock photo or an image-API key anywhere in the chain. A second, deliberately slower instance runs on nowa.dk: one guarded article a week, with a kill switch.
