Trailhead: An Offline-First Outdoor Companion

说明与用途

Trailhead 是一个离线优先的户外伴侣，基于兴趣、天气和季节推荐每日活动，使用本地 AI 和开放数据。

问题

Users want an app that recommends outdoor activities without relying on internet or costly APIs, preserving privacy and zero running costs.

结果

Trailhead delivers an offline-first, privacy‑preserving outdoor recommendation with zero daily cost, using only open-source tools.

工作流

• 1. User opens app and grants location
• 2. App queries local weather via TabPFN microservice
• 3. Gemma 3 generates a daily brief based on interests and weather
• 4. OpenStreetMap + OSRM compute route to nearby park
• 5. App reads brief aloud and displays route

证据

Trailhead is an offline-first outdoor companion. You open the app for 30 seconds. It tells you the absolute best thing to do outside today (based on your interests, the weather, and what's in season).

来源

We built Trailhead entirely on open-source, local AI tooling: Mastra, Ollama + Gemma 3, TabPFN, OpenStreetMap + OSRM.

来源

Our TabPFN microservice is particularly powerful here — it doesn't need to be retrained. It just looks at a tiny CSV of 2 years of local weather data and immediately gives calibrated probabilities for cold snaps, frost risk, and general outdoor comfort without any API calls.
