Snazzy offers a library of customisable live Google Maps interfaces, such as Google Maps without Labels. The service has now added a new feature, which appears to enhance a 1000px screenshot with 3x AI upscaling.
You could do the same with a screenshot utility and Gigapixel AI, but I’d guess that Snazzy is training its AI on map screenshots and small text. Gigapixel AI gives rather poor results on small text.
