Every page below runs the real flow — drop a voice note, watch the words arrive, read the summary. You do not need a key: with no key saved they run a scripted sample at realistic speed. Save your own OpenRouter key and the identical code path does the real thing. Nothing is tracked, nothing is stored anywhere.
These differ in look, and in how you are told what is happening and what comes next. None of them uses the current navy-and-green, deliberately: the test should measure the design, not which one looks familiar.
warm cream · Georgia serif · terracotta · no shadows
Printed and unhurried. A roman-numeral crumb line across the top, and under every button a plain-English line telling you what happens next.
Open Studio →near-black · monospace · teal + amber
A tool that shows its work. A pipeline rail down the left marks every step
[ok] / [now] / [ ], with a live spend
meter against the ceiling.
light violet · rounded cards · phone posture
A phone app on any screen. A four-pill stepper at the top and one sticky bottom button that is always the single next thing to do.
Open Card →Two languages, four cultures. Each pack changes the accent colour, the typography, the shape language, the register and the vocabulary — plus money, dates and number formats. Open one and switch between them in place; the page explains, marker by marker, what changed and why. English (UK) is what the product looks like today; the other three are the new work.
claret · serif · near-zero radius
Understated and indirect. Restraint is the cultural signal.
Open →blue · bold sans · soft shadows
Direct and benefit-first: the headline states the outcome and the time.
Open →azulejo blue · formal register
ficheiro · dispositivo · ecrã. Symbol after the amount, comma decimal.
Open →deep green · softest shapes · warm
arquivo · celular · tela. First person plural, and a circular drop target.
Open →Compare all four side by side → — a matrix of every difference with the reasoning behind each one.
Opinions on any of it are welcome, but these are the questions the test exists to answer:
Honest notes. These are design prototypes, not the shipping product — the
live app is at /app/ and is unaffected by anything here. They run on a
small runtime that exists only under /design/; the product itself has no
framework. The transcript and summary in demo mode are a fixed sample, and the demo is
labelled as costing nothing because it calls nothing. These pages are excluded from search
indexing and from the sitemap.
The reasoning behind both families is public: the design briefs and hand-off packs, and the review that accepted them.
