On Point

Inspiration

Fashion is deeply personal, yet technology has treated it as
one-size-fits-all. We were inspired by the disconnect between AI's
potential and the fashion industry's digital experience. Meanwhile,
blockchain ownership revolutionized digital assets, but fashion NFTs
remained static collectibles disconnected from real utility.

We asked: What if AI could be your personal stylist, AR let you try before
 you buy, and blockchain proved your style ownership — all in one seamless
 experience?

OnPoint bridges these worlds, creating a platform where AI meets fashion,
and digital ownership meets real-world style.

What it does

OnPoint is an AI-powered fashion discovery platform with virtual try-on,
blockchain-based digital ownership, and social sharing:

 - Live AR Stylist: Real-time voice & vision fashion consultations powered
   by Gemini Live — interruptible, contextual, like a FaceTime call with a
   fashion expert
 - AI Collage Creator: Generate personalized fashion designs from images and
    text prompts using multimodal AI
 - Virtual Style Lab: IDM-VTON powered virtual try-on with drag-and-drop
   styling
 - Digital Ownership: Mint fashion items as NFTs on ZetaChain with IPFS
   storage and automated royalty splits (85% creator, 10% platform, 5%
   stylist)
 - Social Loop: Capture AR snapshots with "Proof of Style" and share
   natively to Farcaster
 - Agentic Tipping: Tip your AI stylist in cUSD via Celo — real crypto
   payments for AI services
 - Enhanced Catalog: Premium shopping experience with trending badges,
   engagement metrics, and View Transitions API animations
 - Worldcoin Identity: Privacy-preserving verification for unique human
   users

How we built it

Tech Stack
 - Frontend: Next.js 15 (App Router), React 19, TypeScript, Tailwind CSS,
   Framer Motion
 - AI: Gemini Live (real-time voice/vision), OpenAI GPT-4V, Replicate
   (IDM-VTON for try-on)
 - Web3: RainbowKit, Wagmi, Viem, 0xSplits for royalties, ZetaChain & Celo
   blockchains
 - Storage: IPFS/Filecoin via Lighthouse for decentralized asset storage
 - Social: Farcaster (Neynar API) for decentralized social sharing
 - Identity: Worldcoin World ID for privacy-preserving human verification

Architecture
 - Monorepo: pnpm + Turborepo with shared packages (shared-ui, ai-client,
   blockchain-client, worldcoin-auth, ipfs-client)
 - AI Abstraction: Unified provider interface supporting Chrome, Gemini,
   OpenAI, Replicate, Venice
 - Centralized Data Layer: Single source of truth for fashion items in
   shared-types/fashion-data.ts
 - API Routes: Next.js serverless functions for AI endpoints and Farcaster
   webhooks
 - Premium UI Components: CardEnhanced, ShopGrid, EngagementBadge with 9
   GPU-accelerated animations

Key Integrations
 1. Gemini Live SDK → Real-time AR stylist with WebSocket connections on
    Google Cloud Run
 2. IDM-VTON (Replicate) → Virtual try-on with caching optimizations
 3. 0xSplits → Automated royalty distribution at mint time
 4. Farcaster Compose → Native social sharing with sdk.actions.composeCast
 5. Celo cUSD → Agentic tipping with automatic network switching

---

Challenges we ran into

 1. Gemini Live Real-Time Integration: Setting up uninterrupted voice/vision
    sessions required WebSocket endpoints on Cloud Run with proper
    authentication flow. Balancing low-latency audio streaming with visual
    analysis was complex.

 2. Cross-Chain Web3 Configuration: Supporting ZetaChain (primary), Celo
    (tipping), Base, and Arbitrum required careful Wagmi configuration and
    automatic network switching without breaking user experience.

 3. AI Personality Consistency: Creating six distinct AI stylist
    personalities (Anna Karenina, Miranda Priestly, Artful Dodger, etc.) that
     maintain character while providing useful fashion advice required
    iterative prompt engineering.

 4. View Transitions API Adoption: Implementing smooth page morphing for the
    enhanced catalog required careful state management and fallback handling
    for browsers without support.

 5. IPFS + Blockchain Sync: Ensuring NFT metadata pinned to IPFS stayed
    synchronized with blockchain events across web and mobile clients
    required an event-driven architecture with exponential backoff retry
    logic.

 6. Farcaster Social Integration: Native casting from within the app required
     Neynar API integration and proper frame handling for "Proof of Style"
    snapshots with embedded AR overlays.

What we learned

 1. Multimodal AI is Transformative: Gemini Live's ability to see and hear
    simultaneously creates qualitatively different UX than text-based AI. The
     "interruptible consultant" pattern feels magical.

 2. Web3 Needs Seamless UX: Users don't care about chains — they care about
    ownership. Abstracting ZetaChain/Celo complexity behind simple "Connect →
     Mint → Share" flows is critical.

 3. Social Proof Drives Engagement: Trending badges, animated counters, and
    one-click share buttons create viral loops. The EngagementBadge component
     became our most impactful UI addition.

 4. African Fashion is Underserved: Mainstream AI models lack cultural
    context for African textiles. Our lightweight pattern recognition layer
    showed the potential for specialized, culturally-aware AI.

 5. Performance Matters: GPU-accelerated animations (transform/opacity only)
    and View Transitions API create premium feel without jank. Respecting
    prefers-reduced-motion is non-negotiable for accessibility.

 6. Monorepo Discipline: Centralized data layer (fashion-data.ts) prevented
    duplication and made adding new items trivial. Turborepo pipelines kept
    builds fast.
