We built a simple (48-hour) mobile web app (no signup required) that uses Google Vision AI and the Spotify search API to help you decide what to listen to while you eat.
It's written in Python and hosted on NorthFlank; uploaded and generated images are cached in an S3 bucket.
Future enhancements would obviously be to use a classifier to convert the raw food labels into a more natural "Playlist topic", and perhaps to support SoundCloud or other services.
Currently taking feature requests, bug reports and questions.
