TrailSage AI: Road Trip Guide

TrailSage AI is your private, offline road trip storyteller.

Designed for deep mountain valleys, scenic highways, and remote national parks where cellular service vanishes, TrailSage AI packages on-device Artificial Intelligence, expressive neural narration, and detailed offline maps to tell you the stories of the land as you drive.

🌟 KEY FEATURES

* Powered by Google Gemma 2B and on-device LiteRT.
* Ask questions about surrounding landmarks, local history, geography, or flora and fauna.
* Works completely offline—no cloud APIs, cellular data, or internet connection required.
* Utilizes a localized Retrieval-Augmented Generation (RAG) system for accurate, context-aware responses.

🗣️ NATURAL NEURAL VOICES
* Driven by the Sherpa-ONNX synthesis engine and VITS voice profiles.
* Experience highly expressive, natural human voice tours instead of robotic system text-to-speech fallbacks.

* Track paths, trails, roads, and topography with zero latency.

🔒 PRIVACY-FIRST DESIGN
* Your trip history, routes, and location coordinates stay on your device—never sold or shared.
* On-device AI and narration mean your questions and travels never leave your phone.
