ContextCity // one codexierge to guide 'em all
GPT-5 Startup Hackathon NYC- We built the ContextCity Codex concierge: an Expo mobile experience where Dartagnan guides travelers through city highlights. - GPT-backed workers curate social signals into reels, Remotion renders localized MP4s, and the app surfaces rationale, itinerary, and concierge cues. - A “Route to {POI}” card and localized overlay tie reels directly to multi-step actions (plan, book, guide, celebrate). - The demo showcases Felix in SoHo across French, English, and Spanish, including synchronized narration, subtitles, and concierge voice.
