Google briefly released the COSMO AI assistant app for Android, a 1.13GB tool designed to run local Gemini Nano models and automate on-device tasks.

Google briefly published an experimental AI assistant app called COSMO to the Play Store on May 1, 2026, before pulling the listing just hours later [1]. The app, which requires a 1.13GB download, appears to be a developmental testbed for an on-device AI agent capable of deep context awareness [2, 3].

Unlike standard chatbots that require users to switch apps and manually input prompts, COSMO is designed to monitor screen activity via Android’s AccessibilityService API [1, 3]. By observing what is on the display—such as text messages or browser tabs—the assistant can proactively suggest tasks like scheduling calendar events, drafting documents, or setting timers [2, 3]. The app features 14 specific skills, including "Deep Research" for complex queries and "Browser Agent" for automating web-based tasks [2, 3].

A core component of the app is its ability to process data locally using Google’s Gemini Nano model, which allows for offline functionality and potentially greater privacy for sensitive on-screen content [2, 3]. Users can toggle between three "Fulfillment" modes: a "Nano Only" local mode, a "PI Only" server-side mode, or a "Hybrid" setting that automatically switches between the two based on the complexity of the task [1, 3].

The app’s premature release was marked by technical inconsistencies, including poorly formatted screenshots and a bare-bones interface, suggesting it was not yet intended for public use [1, 3]. While Google has not officially announced the tool, the timing of the leak—just weeks before the Google I/O developer conference—has led to speculation that COSMO serves as a testing ground for features that may eventually be integrated into the broader Gemini ecosystem or the Android operating system itself [2, 3].

Whether COSMO will eventually launch as a standalone product or remain a behind-the-scenes research project remains unclear. For now, the app’s brief appearance highlights Google’s push to move AI from simple text-based chat interfaces toward proactive, system-level agents that manage daily digital chores.
