I'm Chang Mou, a product designer working on what AI can't design yet.

Deciding what to build, where a person stays in control, and what is actually good enough to ship.

Background

I'm based in San Francisco, open to relocating, hold a Master's in Interaction Design, and work on AI products., open to relocating, and hold a Master's in Interaction Design. I work on AI products, and specifically on the parts a model cannot take off your hands: deciding what to build, where a person stays in control, and what is actually good enough to ship.

I run the research and build my own prototypes: in Figma when that is the right tool, in real code when a spec would lose too much, so the team gets a working build to extend, not a spec to translate.

I want to make people's lives better by designing how a person and a computer collaborate. AI should augment what someone can do, not decide for them, and my part is finding where that line sits. The model gives the hours back, and judgment is what they are for. Designers get more powerful in the AI era, not less.

Outside of work, I cook, walk the city on foot, read widely, vibe code some gimmicks, and spend time with friends. I listen to a lot of music, and more of my ideas come from it than from any designer. Nothing stays in its own field for long, and design is where it all connects.

How I use AI

AI's first pass drifts toward generic, so it never gets the last word. It runs the busywork; framing the problem, choosing the direction, and deciding what ships stay with me. The rule I work by is the one my products ship with: a human stays in the loop. AI accelerates everything and decides nothing. The judgment is the job.

One session, 29 July 2026 Claude Code, on a product's v2

Chang

just compare v2 and v1 in your opinion. if v1 is better why i do v2

Claude Code

Here's my actual opinion: v2 is the better product. Not the better-executed one today, v1 is more polished where it counts, but the better architecture. And architecture wins, because polish transfers and skeletons don't.

Claude Code, continued

[three paragraphs of reasoning]

Notice what my strongest v1 arguments actually were: matrix width, decision gravity, re-entry after six months. Those are execution problems inside v2. They're not arguments for v1's architecture. The asymmetry is the answer: v2 has fixable weaknesses, v1 has a foundational one.

Chang

do not change the structure but check the latest design principles on agentic workflow design. what you suggest I can improve this project?

Claude Code

Research fleet is out, four parallel sweeps: lab guidance from NN/g, PAIR, HAX, Anthropic and OpenAI; teardowns of ChatGPT Agent, Devin, Manus, Cursor, Comet and Mariner; trust-and-oversight literature; consumer-delegation patterns like agentic checkout. When they report back I'll synthesize the findings against v2 and give you a prioritized list that leaves the three-pane structure alone.

Chang

do 2,1,5,7

Chang, forty minutes later

push to main as V2, do not touch v1

Shipped

The same morning, as homewise-v2.vercel.app. The opinion was the agent's; the structure, the shortlist and the ship call were mine.
