Zaikan · AI product

I designed and shipped a read-it-later product end to end with Vibe Coding, and recast the delivery loop: from a linear define–design–build–iterate chain to a mesh of decisions made on a working product.

Ship something usable,
then decide together.

After leaving a large company I wanted to test whether one person plus AI tools could take a product from an idea to launch.

Zaikan gathers pages, articles, videos, images, PDFs and notes in one place — for deep reading, organising knowledge and saving ideas. I owned the product form, the visual language, and the AI collaboration itself.

Define

Product form

Save it, sort it, come back to it — one clear loop.

Guide

Visual language

Whitespace, illustration and light type, so reading is the product.

Explore

AI workflow

Decide on a working product, not a finished spec handed to engineering.
