Google has launched the COSMO AI assistant app for Android, offering smarter automation, enhanced features, and improved user experience across devices. COSMO is an experimental AI app that focuses on proactive AI. COSMO is a development testbed, not a consumer-ready app.
Google has launched ‘COSMO,’ an experimental artificial intelligence (AI) assistant app for Android devices. The app is available on the Play Store and appears to come from Google Research. COSMO leverages AI to simplify day-to-day tasks such as organizing schedules and answering complex queries. The app weighs in at a hefty 1.13 GB due to a local Gemini Nano model it includes.
The new app, arriving with the package name com.google.research.air.cosmo, is described by Google as ‘an experimental AI assistant application for Android devices’. The company goes on to explain: COSMO's Play Store history: ‘Here yesterday, gone today.’
The experimental AI assistant app and features simplify your life by working behind the scenes. COSMO operates on-device, whereas Gemini is mostly cloud-based.
Instead of responding to a prompt, COSMO listens to what is happening and automatically responds to users via ‘Skills.’ Here are some of the things that COSMO can do:
Quick Photo Lookup: When users mention a specific photo in conversation, COSMO offers to find it on your phone.
Calendar Event Suggester: Proactively offers to schedule a meeting when it detects users deciding on a meeting time with someone.
Document Writer: If individuals mention that they need a document, COSMO will automatically draft a letter or will summarize a text.
Context Awareness: COSMO will know what users are doing as it uses Android's AccessibilityService API to ‘see’ the screen.
Jargon Definition: If there is an acronym or jargon, COSMO will explain it to users.
Recall: If users can't remember something, COSMO will show them things that people are trying to remember.
Add Timer: If users mention a task that requires a timer, COSMO will ask them if it should create one in the Clock app.
Events Understanding: Provides context about events.
People Understanding: Provides context about people.

Users can choose from three modes (Hybrid, PI Only, or Nano Only) in the settings page. However, Google hasn't clarified what "PI" stands for yet. The app also lets you set up voice match and grant screen access to further enhance the user experience. This feels like a premature, or accidental, release before Google I/O 2026 later this month.
