Side Quest: an AI that sends you on a walk, and never learns where you are

说明与用途

Side Quest 是一个步行寻宝游戏，使用浏览器中的开源 LLM 生成线索，保护用户位置隐私，依赖开放数据源。

问题

Most AI‑outdoors apps keep users looking at the screen while walking, reducing real‑world engagement.

结果

Side Quest delivers a privacy‑preserving, low‑cost walking scavenger hunt that limits screen time to ~10 s per stop, keeps location data local, works offline after first run, and uses open data sources.

工作流

• 1. User selects walk duration (15–60 min) and clue style (playful, poetic, detective, kids).
• 2. App snaps current location to a 0.01° (~1.1 km) grid and queries OpenStreetMap and Wikipedia for nearby points of interest.
• 3. A deterministic planner selects 2–4 varied stops that fit the requested time.
• 4. Gemma (WebLLM on WebGPU) writes a riddle and a sensory notice for each stop.
• 5. User walks, checks in at each stop, receives the notice, and proceeds to the next clue.
• 6. After the final stop, Gemma writes a three‑line postcard summarizing the walk, saved only on the device.

Gemma writes a riddle for each stop

The app finds a few interesting places within walking distance (a temple, a mural, an old bookshop, a pond) and plans a loop that fits your time.

Gemma, running inside your browser, writes a riddle for each stop.

The only network requests are the map lookups, and even those never carry your exact position.
