A video pitch in the morning, a documented product by evening: project page, EU compliance papers, assembly instructions, safety information in 25 languages. Most of the grunt work was Claude’s, working from the video transcript and my prompts; I edited, fact-checked, and made the design and compliance calls.
The product
VÄGGRULLE — Swedish for “wall roll” — is a wall-mounted paper holder with one twist: paper feeds from the bottom, not the top. Bottom-feed matches how we write — when you need more space you get it below what you’ve just written. Magnets hold the paper flat so you can write on it like a whiteboard, but nothing ever needs to be erased. Receipts and to-do lists roll quietly into an archive. Four pieces of 0.8 mm steel, four spacers, four screws, two magnets.
What we built
Four interlocking documents: a customer-facing project page, a README in our minis repo, separate assembly instructions, and a technical-documentation file behind the EU Declaration of Conformity. The website page is the brochure; the minis-repo files are the receipts. A visitor can get from a one-line tagline to tech specs and CAD files in a few clicks.
The compliance work — an internal safety assessment, safety warnings in all 24 official EU languages — is the kind of slog Claude is genuinely good at: structured, regulated, repetitive. The judgement calls were mine; the drafting was its. AI makes this kind of work tractable for a small studio.
