WildPack: A Local-First Trail Guide with Gemma

Description and use

WildPack shows how a local‑first trail guide can operate offline, store data locally, and answer questions using a local Gemma 3 4B model.

Problem

Hikers need a trail guide that works offline and keeps sensitive location data local.

Outcome

WildPack demonstrates that a local‑first trail guide can provide route replay and AI question answering without internet, preserving user privacy and enabling offline use.

Workflow

• Import a .wildpack file into the browser
• Add or edit observations in the local storage
• Replay a synthetic GPX route in the browser
• Ask a question about the trail or pack
• The app sends the query to the local Ollama Gemma 3 4B model and returns an answer
• (Optional) Use ElevenLabs integration to generate narration for a pack

Evidence

WildPack is a desktop‑first, local‑first trail‑guide prototype. It stores imported .wildpack files and observations in this browser, can replay synthetic GPX routes, and can use Ollama on the same computer for pack‑grounded questions

The bundled demo route and its natural‑history text are synthetic: they are not a real trail, species record, or source of outdoor‑safety advice.

For AI, I used Gemma 3 4B through Ollama for local model features and EmbeddingGemma for embeddings and retrieval.

I also added an ElevenLabs integration path for narration generation in the pack builder.
