i build an opensource mobile browser - we create ai agents (that run in the background) on the mobile browser. and build an extension framework on top so u can create these agents by publishing an extension.
we hook into the android workmanager framework and do some quirky things with tab handling to make this work. its harder to do this on mobile than on desktop.
bunch of people are trying to do interesting things like an automatic labubu purchase agent (on popmart) :D lots of purchase related agents
