Google has accidentally revealed details of a new AI assistant called COSMO after a test app briefly appeared on the Play Store. The leak, just weeks before Google I/O 2026, suggests the company is preparing a major upgrade to how AI works on smartphones.
COSMO moves beyond traditional assistants
COSMO is designed to work differently from tools like Google Assistant or Gemini. Instead of waiting for commands, it can understand context and act on its own. It works in the background, observing what the user is doing and offering help when needed.
This means fewer manual searches, fewer voice commands, and faster task completion. The goal is simple: reduce friction in everyday phone use.
Built on-device with smarter processing
A key part of COSMO is that it runs directly on the device using Gemini Nano. This allows it to respond instantly without relying fully on the internet.
This also improves privacy, since sensitive data can stay on the device instead of being sent to the cloud.
At the same time, COSMO can switch to cloud processing for more complex tasks. This hybrid system allows it to handle both quick actions and advanced requests efficiently.
Understands your screen in real time
One of the biggest changes is COSMO’s ability to read and understand what is happening on the screen.
It can:
- Detect conversations
- Recognise tasks
- Identify important information
For example, if you are chatting about meeting someone, it may suggest adding a calendar event. If you are reading a long article, it can summarise it instantly.
This makes interactions faster and more natural.
Designed to complete tasks, not just answer
The leaked features show COSMO is built for action, not just conversation.
It can:
- Suggest events automatically
- Find content like photos using context
- Write and summarise documents
- Combine data from multiple sources
- Perform actions inside apps and browsers
This is a step toward AI that acts more like a personal assistant than a search tool.
Part of a larger industry shift
The leak shows Google is moving toward deeper AI integration at the system level. Instead of separate apps, AI is becoming part of how the entire device works.
This matches a wider trend in the tech industry. Companies are focusing on AI that can anticipate needs, automate tasks, and improve productivity without constant input.
It also reflects growing competition in AI, where companies are trying to build assistants that are faster, smarter, and more useful in daily life.
What happens next
It is not yet clear how Google will launch COSMO. It could be released as a standalone product or built into existing services like Gemini or Android itself. The leaked version appears unfinished, so features may change before release.
However, the direction is clear. AI assistants are moving from tools that respond to questions to systems that understand users and take action.
With Google I/O 2026 approaching, COSMO is likely to be one of the most important announcements to watch.
