Elizabeth Xu, product builder in New York

The EU's ESPR regulation is bringing digital product passports to fashion. Compliance data will become table stakes for every brand. The experience built on top of that data is where brands will differ, so I prototyped that layer: a tag-scan flow, provenance and care, in three languages.

Figma first, then a solo build. The voice layer runs on ElevenLabs so the jacket can speak, and the whole thing is designed to feel like a clothing label rather than a compliance form. Sixteen screens, deployed.

Most AI writing tools rewrite you. Cadentia reflects you instead: it shows how your language changes from person to person, then tracks those patterns over time in a journal and a constellation of saved reflections. The model interprets; it never takes over your voice.

Art-directed like an heirloom powder compact, not a chat window. A breathing compact opens with a clasp release, an engraving circles inside the glass, and every icon is drawn by hand in SVG. Restraint was the spec.

You enter your birth date, time and place. The app computes the Moon's phase and position with an astronomy library, deterministically, so the data is real. AI is only allowed to reflect on what you write back. Scoping the model tightly is the product decision.

No horoscope dashboard, no chatbot, no streaks. Ink-black night, warm moonlight, lantern gold and osmanthus, with a red lantern that opens the experience. It borrows its pace from In the Mood for Love.

An interactive knowledge graph of my professional identity, drawn as a lotus on canvas. Built with React and the Canvas API, and deployed in a single day.

A conversational agent that asks about your travels and grows each memory into a blossom on a tree. You talk; the tree fills in.
