Loopsmith: tell it how far you want to go, get a GPX loop (open-weight model, fully local)
This is a submission for the Hacktoberfest Open-Source AI Challenge Week 1: Touch Grass What I Built Loopsmith turns a sentence like "a 6 km easy run, ending where I start" into a GPX loop you can load on your phone or watch. A small open-weight model running locally through Ollama reads the request. The route itself comes from GraphHopper on OpenStreetMap data. The Java backend only talks to…
Loopsmith is a tool that converts a request for a run or walk of a specific distance into a GPX file that can be downloaded and used on a phone or watch. It uses an open-weight model running locally through Ollama to interpret the request, and the route is generated by GraphHopper using OpenStreetMap data. The tool is designed to be used without an account and without sending the start point to a third party.
A demo of Loopsmith is available locally, and the code is open-source on GitHub. The tool was built for the DEV Hacktoberfest Open-Source AI Challenge, week 1, which encourages people to get outside and enjoy a walk or run without being tied to a screen. The demo shows that Loopsmith can generate a loop that is slightly shorter than the requested distance, but still within an acceptable tolerance. The tool is built using Java, Spring Boot, Ollama, GraphHopper, and OpenStreetMap data.
