Developer creates AI-powered outdoor activity planner using open-source tools

·3 views

A developer created an application called TouchGrass that generates personalized outdoor activity plans. The tool uses Python and Streamlit to combine location data from OpenStreetMap, weather information from Open-Meteo, and a locally-run Llama 3.2 AI model via Ollama.
