Ask in your own language, keep London place names grounded in English, and stay oriented when the signal drops. Built for tourists who need local guidance instead of map-only guesswork.用你自己的语言提问，伦敦地名始终锚定在英文，信号中断时也不会迷路。为需要在地指引、而不是只对着地图猜路的游客而做。
Ask in plain language — "Waterloo to Baker Street", or tap a suggestion. Everything routes on your device; tap the status indicator to toggle airplane mode and it keeps working.用日常语言提问——"Waterloo to Baker Street"，或点一个推荐。所有规划都在你的设备上完成；点状态指示器切到飞行模式，它照样能用。
This demo reproduces the GO screen with a simplified offline network. The shipping app goes much further:这个演示用一个简化的离线网络复刻了 GO 界面。真正发布的应用走得更远：
Dijkstra shortest-path over a TfL-sourced graph (Tube, DLR, Elizabeth line, Overground) — 575 segments, fully offline.在 TfL 官方数据构建的图上做 Dijkstra 最短路径（地铁、DLR、伊丽莎白线、Overground）——575 段线路，全程离线。
Gemma 3 (1B, GGUF via llama.rn) extracts intent to structured JSON — it never resolves locations itself.Gemma 3（1B，通过 llama.rn 跑 GGUF）把意图抽取成结构化 JSON——它从不自己解析地点。
An EntityResolver matches every place against local indices first; low confidence shows disambiguation, not a hallucination.EntityResolver 先把每个地点对照本地索引匹配；置信度低时弹出消歧选项，而不是凭空编造。
Museums, galleries, landmarks via SQLite FTS5; voice input in 140+ languages with OS-native speech & TTS.博物馆、画廊、地标通过 SQLite FTS5 检索；140+ 种语言语音输入，调用系统原生语音识别与 TTS。
