What Ace is

Ace is a voice-first AI travel concierge that lives on your phone. You speak once, naturally. Ace finds the route, applies your railcard, quotes the fare, takes one tap to confirm, and delivers a ticket to your inbox — without you touching a form or switching a tab.

It is not a chatbot. It is not a booking engine with a voice layer bolted on. Ace is an economic agent: it holds your preferences, executes autonomously, and stays with the trip after booking — watching for delays, platform changes, and disruptions.

"Book a train from London Paddington to Bristol Temple Meads, tomorrow morning, cheapest."

Ace: Done. £24.50 · 07:04 depart · ticket to your inbox.

Key capabilities

The Ace presence layer

AceFace is Ace's voice presence — a GPU-rendered sculptural bust that reacts in real-time to speech energy, mic amplitude, and phase state. It is not decorative.

• Metal GPU pipeline — @shopify/react-native-skia, runs on the UI thread via Reanimated worklets
• 11 render layers — atmospheric halo, listening rings, 3D bust PNG, focus field, key light, rim light, inner shadow, lower-face tension, mouth cavity + lip line, ghost rim, audio-reactive corona
• Real speech sync — TTS amplitude drives jaw, viseme-oo, viseme-ee blend shapes at ~60fps
• Phase-aware — idle / listening / thinking / confirming / executing / done / error each have distinct animation signatures
• No hallucination silence — CF Whisper hallucination detection + OpenAI Whisper fallback means Ace never transcribes "Thank you for watching." as a booking intent
