TerraTale app creates a personal treasure map that expands as you walk

TerraTale is an open-source project that generates a personal, local map that fills in only as the user physically walks through their neighborhood. It starts as a blank parchment centered on the user's home location, with each real-world walk inking in the specific areas covered. The app uses two AI models: TabPFN to classify locations based on user data and Gemma to generate descriptive legends, with all data processed locally on the user's device. The design philosophy prioritizes the physical experience of walking over digital metrics, rewarding users with a growing, printable map. The project was developed for the Hacktoberfest Open-Source AI Challenge and is available on GitHub.
