Google's COSMO App Leak Hints at a More Agentic Gemini on Android

The Google COSMO app was never officially announced. It briefly appeared on the Play, then disappeared just as quickly. That usually means one thing: this was not ready for the public. Still, accidental releases can be revealing. If the reported COSMO feature list is even mostly accurate, Google may be testing a agentic Android assistant that blends on-device AI, web actions, memory, and research workflows into one surface. Why This Matters Most AI assistants still feel fragmented.
