Rapid Editor

Rapid is a browser-based editor for OpenStreetMap that overlays features predicted from satellite imagery, shown as a magenta layer. Mappers review the suggestions and add the correct ones to the map instead of tracing them by hand.

It is aimed at volunteer and professional mappers who want to add roads and buildings faster, working alongside the usual OpenStreetMap editing tools. The project is open source and has a presence on Mastodon. The page we reviewed gave little detail beyond the core idea, so check the project site for supported data sources.
