✦ BoothPilot

The AI booth concierge that turns a hallway conversation into pipeline.

A visitor walks up. Ninety seconds later they've had a real conversation, seen the product demo their exact problem, and walked away with a shareable badge — while the team gets a scored lead and a ready-to-send follow-up.

---

BoothPilot is a live conference-booth concierge for a (fictional) SaaS, Quill — an AI customer-support agent. It captures the visitor conversation by voice, enriches the lead in real time, drives an on-screen product demo tailored to what they actually said, scores the opportunity, mints a shareable Booth Badge, and drafts a human-reviewed follow-up email. It runs on an iPad in a fully 3D-printed stand — the iPad is a kiosk shell around the deployed web booth, so it behaves exactly like the live site.

Built for the sponsor stack: OpenAI · Convex · Cursor · fiber.ai · ElevenLabs.

✷ The ninety seconds

1 · Walk up	The booth greets the visitor by voice (OpenAI Realtime).
2 · Identify	Scan a LinkedIn QR or just say your name + company → fiber.ai enriches you into a live CRM card (firmographics, role, work email).
3 · Demo	The agent drives the Quill product to the visitor's exact use case — shared-state, not browser automation, so it never breaks.
4 · Score	Confidence + urgency are computed in the background, with reasons — never shown to the visitor.
5 · Badge	The visitor gets a shareable, collectible Booth Badge — an archetype, a grounded compliment, stat bars, and a discount, via QR.
6 · Follow-up	The team gets a drafted email in a review queue. Nothing is ever auto-sent.

Loading

• convex/ — the realtime spine: sessions (the CRM card), transcript, demo state, fiber enrichment, lead scoring, badges, the email review queue, and the llmJobs queue.
• dashboard/ — Next.js app: the web booth (/booth), the live demo (/demo), shareable badges (/badge + Open Graph image), and the review queue (/review).
• llm-worker/ — a local pull-worker (OpenAI Codex SDK) that claims llmJobs, returns strict JSON, and writes the final score / badge / email back through Convex. finalize never sends email — if the worker is offline, Convex finishes the card with a deterministic safety fallback after ~25s.
• ios/ — the SwiftUI kiosk that loads the web booth in a full-screen WebView and grants it mic + camera natively.
• hardware/ — the parametric, fully 3D-printed iPad stand.

✷ The booth, in the flesh

Parametric, 100% printed joinery — no fasteners.

✷ Run it locally

Three terminals from the repo root:

# 1 — Convex spine
npx convex dev

# 2 — dashboard + web booth
cd dashboard && npm install && npm run dev

# 3 — local Codex worker (scoring / badge / email)
cd llm-worker && npm install && npm start

The dashboard reads dashboard/.env.local:

NEXT_PUBLIC_CONVEX_URL=https://<your-deployment>.convex.cloud

Handy:

npx convex run seed:run            # seed demo data
npx convex run sessions:list '{}'  # inspect the CRM cards
node scripts/simulate-visitor.mjs  # drive a fake visitor end-to-end

Email stays human-in-the-loop: review a draft in /review, approve or edit, then send. Real sends require RESEND_API_KEY + a verified sender.
