TrailQuest is an AI-powered outdoor activity idea generator, built using the open-weight Gemma 4 E2B model. This innovative tool enables users to generate personalized outdoor missions based on their interests, available time, preferred pace, mobility needs, and social preferences. By encouraging people to spend more time exploring the world outside their screens, TrailQuest aims to make stepping outside feel approachable and easy to incorporate into daily life.

After completing a mission, users can provide feedback on their experience, which helps the system refine its future suggestions. The application utilizes the Gemma 4 E2B model, which runs locally via Ollama, allowing users to generate missions without relying on a proprietary, hosted AI API. This open innovation approach makes experimentation more accessible and enables developers to learn about how AI systems function in a practical application.
