01 / Overview

How to make an AI
feel real

Shipped & Live on App Store

Loneliness is a design problem nobody was solving well. Existing AI companions offered conversation — but not presence. They responded, but didn't feel alive. For anime enthusiasts who already form deep emotional bonds with fictional characters, the bar for believability was even higher.

The question wasn't how to build an AI. It was how to make one feel real.

02 / My Role

Sole designer across
three universities

As the sole product designer on a 12-person cross-university team — UVA, SJSU, and Harvard — I was the connective tissue between art direction, engineering, and LLM teams. Four distinct workstreams, all converging on one product.

🖥
Product Design & Design System
End-to-end UX/UI in Figma — screens, flows, component library, and a design system shared across the team. App architecture, onboarding, companion chat, and settings.
🎨
Character & Game Logic Design
Directed the full character pipeline — sketch → greyscale → color — and defined game mechanics: affection system, daily missions, and the emotional state logic that shaped each character's responses.
📣
Marketing & Pitch Material
Designed pitch decks, investor one-pagers, and the XFund presentation. Also directed the IP-first TikTok strategy — weekly anime comics before a single line of app code shipped.
🏆
UVA eCup & Competitions
Represented Kimi in UVA's entrepreneurship competition (eCup) alongside the XFund GenAI competition at Harvard — building the narrative and visual materials for both.

Character Design — When Research Isn't Enough

The first character designs followed the research exactly — and landed completely flat. Users recognized them but felt nothing. That gap between what people describe and what actually moves them became the defining design lesson of this project.

The Fortune Teller wasn't arbitrary — she was the answer to a real behavioral pattern: users turning to AI not for conversation, but for guidance and meaning. Both characters were scrapped and rebuilt from scratch, leading with personality, backstory, and emotional register.

03 / Research

300 surveys.
One real insight.

300 surveys across US universities surfaced the real insight: users didn't want more AI capability — they wanted to feel seen. Anime enthusiasts were underserved by every existing product. The team narrowed hard: stop competing with Character AI head-on, own the niche entirely.

🔍
The Real Need
Users weren't seeking more AI capability. They were turning to AI for guidance, reassurance, and meaning — not just conversation.
🎯
The Niche
Anime enthusiasts already form deep emotional bonds with fictional characters. The bar for believability was higher — and the market was entirely unserved.

Stop competing with Character AI. Own the niche entirely.

Presence over performance — users wanted a companion that felt alive, not one that answered questions faster.
Meaning over mechanics — the emotional register mattered more than feature depth or conversation quality.
The gap between description and feeling — what people say they want and what actually moves them turned out to be very different things.
05 / Launch & Traction

Ship the world
before the app

When dev timelines slipped, the team shifted to IP-first marketing — weekly anime comic drops on TikTok, a Discord built around the characters. By launch, 130+ seed users were already emotionally invested. Emotional PMF was validated before the interface existed.

With Sam Altman after the pitch

On May 1, 2024, the Kimi team pitched at Harvard to Sam Altman, CEO of OpenAI — one of six founding teams selected from 270 submissions, competing for a $100K+ investment in a field spanning defense, research, and enterprise AI.

Getting into that room required more than a good idea. The pitch was built on a clear story: a niche deeply understood, a live product already in users' hands, and a design philosophy that bet on emotional authenticity over feature breadth.

vs defense, research, enterprise AI

Kimi was my first time seeing the full arc of a product — from a blank Figma file to something real people downloaded and talked about. It changed how I think about design: not as a discipline that sits downstream of decisions, but as something that shapes them from the start.

Working 0→1 meant the design work was inseparable from the business thinking — research, positioning, character strategy, pitch narrative all lived in the same room. My background across technology and design let me move between those conversations without losing either thread.

The bigger lesson was that design is never the center of things. A product gets built when engineering, research, and strategy are all pulling together. My job was to translate between disciplines and keep the user's perspective in the room — especially when it wasn't otherwise represented.
