LiveAI personal color serviceLive now

Clad

AI personal color service

A live web service that turns two questions and one photo into a personal colour card — the season, the colours that suit, and the ones better kept away from the face — and says so out loud when several photos disagree.

How it was built

How the analysis became a usable decision

The same service principles and evidence carry from the moment a photo is submitted to the moment someone understands the result and chooses colors or products.

The question I want feedback on now

Which part of the result helped you understand it, and where did choosing from the palette or recommendations become difficult?

HappyBirthTown

A pixel town friends build together and hand over as a birthday gift

A pixel town friends grow together and hand to the birthday person as a gift to walk into. Each friend who leaves a letter, a photo, or a drawing plants a tree, the town blooms on the birthday, and all twelve towns can be tried on the web without an account.

How it was built

How scattered birthday wishes became a town to hand over

The product takes the birthday wishes that drift past in a message thread and turns them into a place friends build together and give once, to see what the birthday person is left holding.

The question I want feedback on now

When several people prepare one birthday gift together, what has to reach the birthday person for it to feel properly given — and what makes it feel empty?

LiveConsumer AI serviceLive on the web since 2026

somesignal

A live service where the connections you make accumulate as a map

A live service that reads a relationship through MBTI and saju, Korean four-pillars astrology, without asking anyone to sign up first, and keeps every connection made afterwards as a star on a constellation map.

How it was built

How a compatibility reading turned into a relationship map

The product began as a reading two people could talk about, and operating it moved the centre of gravity from the reading to the map of connections it left behind.

The question I want feedback on now

What would make a lightweight relationship product worth returning to after its first result?

Public demoKBO game companionPublic demo in 2026

DUGOUT 9

A KBO fan service connecting today's game with baseball memory

An independent fan project, published as a public demo and not an official KBO service, that brings a chosen team's starters, recent form, history, and daily games into one game-day flow — and keeps a record of the games you went to in person.

How it was built

How today's game context and a fan's baseball memory became one flow

The product brings scattered game information and fan content into a team-first game room, then adapts the experience across pregame, live, and postgame moments while designing a reason to return.

The question I want feedback on now

What do you check first when preparing to watch your team's game, and what would make you return after the final out?
