I am using the UI Vision extension for a few months now. It is not very fast, but it always works. It can extract text and data from images and canvas elements, too.
My Model 3 adds 17km/h at 220V (EU). => 200 km range if you arrive at 6pm and leave at 8am. THis is not a full charge, but it is more than enough for my daily routine.
But I understand, there might be some use cases where this is not enough.
"I’d have to log into GCloud console every once in a while to check if I still have enough credits" => that is the perfect task to automate with "Kantu".
