I built Galuchat, a compact reverse-geocoding system that works without an external geocoding server or API.The same basic approach can be used in:Browsers WebMCP ESP32 RP2040 / RP2350 JavaScript / C++ / Java / PythonThe basic idea is to store the administrative-boundary data locally and perform the lookup directly on the device, instead of sending every coordinate to an external API.Rather than storing the original polygon data as-is, Galuchat converts administrative regions into a very large raster segmentation image.The raster uses resolutions ranging from roughly 10 m to 1 km per pixel. It is then compressed into a binary representation small enough to be embedded in MCU flash or downloa

The company sits in the show hn launch segment, where it competes on its core product or service.

Directory data places it at the Show HN launch stage.
