Google has accidentally revealed details of its upcoming AI assistant, COSMO, after an experimental app briefly appeared on the Play Store and was quickly taken down. The app, reportedly sized at around 1.13 GB, was uploaded on May 1, 2026, and was soon downloaded and analysed before being removed. The leak comes just ahead of Google I/O 2026, where the company is expected to unveil its latest AI innovations.
COSMO is described as a next-generation AI assistant that moves beyond the traditional model of responding to user commands. Instead of waiting for prompts, it is designed to work proactively by understanding context, observing user activity, and offering assistance automatically. This marks a shift from reactive AI tools to systems that can anticipate needs and act more independently.
The assistant is expected to run using a hybrid AI setup, combining on-device processing through Gemini Nano with cloud-based computing for more complex tasks. This approach is aimed at improving speed, performance, and efficiency while also enabling more flexible real-world use across Android devices.
Leaked details suggest Google’s upcoming COSMO AI assistant comes with advanced capabilities, including real-time screen awareness and a range of automation features designed to make device interaction more proactive and context-driven.
Key features include:
Real-time screen awareness to analyse on-device activity and offer contextual suggestions
Automatic calendar event suggestions based on detected information
Conversation summarisation for quick understanding of discussions
Context-based photo retrieval from device storage
Assistance with writing, editing, and document-related tasks
Browser automation to perform actions directly on websites without manual input
The leak indicates that Google is increasingly focused on building AI systems that are deeply integrated into devices and capable of completing tasks rather than simply generating responses. COSMO appears to reflect this broader strategy of developing more intelligent, context-aware assistants that can function across multiple layers of user activity.
While the official launch details have not been confirmed, COSMO is expected to be part of Google’s wider AI roadmap, with more information likely to be revealed at Google I/O 2026.
