hello

hi there!

I'm Chris Chon.

A lead product designer in San Francisco. I build AI health products people can trust, and the teams and systems that ship them.

About me

About me

Eight years of designing health, fitness and commerce products, from apple.com to an AI health coach.

Today I lead product design at Thrive AI Health, where I designed the AI coaching engine and lead the design team. At Sesame, I partnered with the CPO and CTO to expand from pay-per-visit care into membership programs, so patients who needed ongoing care got it. At lululemon, I led the app design system and the launch of lululemon Membership.

Along the way I've grown design teams and led three design systems. My work lives where trust decides everything, and where research and data, not opinions, decide what gets built.

  • Raise the bar for thinking. At Thrive AI Health I set a culture of systematic design thinking, from problem framing through UI craft.
  • Bring evidence to the roadmap. At lululemon I used churn data to get connectivity prioritized, then cut churn citing it from 40% to 2%.
  • Build systems that speed teams up. I lead Thrive AI Health's design system, co-founded Sesame's Tahini and led lululemon Studio's, which raised developer productivity 64%.

Live demo

The model fills in the card. The design system draws it.

Type a health goal. The AI returns six short fields, and the UI decides how they look and how long they can be.

Your next small step

How it's constrained

  • 1Fixed componentsThe model fills six fields. It can't add buttons, change the layout or write free-form UI.
  • 2Design tokens, not model choicesThe pillar comes from a fixed list, and the design system maps it to color.
  • 3Length limits in the UIEvery field has a character budget, so a long answer can't break the card.
  • 4A safe path for medical questionsSymptoms or treatment questions get a referral card, not advice.
  • 5A designed failure stateIf the output doesn't fit the contract, you see a friendly fallback, not a broken card.

Principles · designing with AI

Point of view

How I design with AI

Five principles I design by. Each one is running somewhere on this canvas.

  • Show the plan, then act

    The AI guide lists its steps before it moves, and a Stop button is always one tap away.

  • Answer from sources

    Every answer links back to the frames it came from, so you can check the work.

  • Design the system, not the sentence

    The model fills in fields. The design system owns layout, color and limits.

  • Say what you don't know

    Job tours list what this portfolio doesn't show, and the guide sends you to me when it can't answer.

  • Keep people in control

    Anything the AI makes can be stopped, dragged, dismissed or cleared.
