Tangential, but does anyone know if an app exists that that the video feed of your phone with the GPS loc and reads the signs from the road and compare it to OSM to update it if necessary?

Let’s be clear, in the end I use Waze for routing due to the traffic updates, but I see sometimes outdated speed limits and know OSM is one of its sources.

I remember seeing something like this where it could identify signs and things, but the quality from what I recall was not great (could be way off and have many duplicates). I might be remembering Mapillary, which has a Map data button at the top left and seems to show signs [0]. I don't think it auto-updates OSM based on these data.

Oh I don't have a link but there was a project just like this someone hacked together a while back. I think it used Gemini live or something and as you walked and scanned things it would suggest changed to the map. It was a rough demo but seemed promising.

I've been wanting to do something similar but just by taking photos of menus and updating the POI with new hours/website/phone etc

Looks like a glue-together narrow-purpose kind of app that AI is relatively good at producing.
