Yesterday, Google released COSMO, an “experimental AI assistant app for Android devices,” on the Play Store.
Refresh: COSMO has since been removed from the Play Store. It was a random release after all.
This app comes from Google Research – com.google.research.air.cosmo — but was published on the company’s main Play Store account.
The listing explains “how COSMO brings the power of artificial intelligence directly to your device.” Use cases include “organizing your day to answer complex questions.”
COSMO is an experimental AI assistant app for Android devices. COSMO brings the power of artificial intelligence directly to your device. From organizing your day to answering complex questions, COSMO works behind the scenes to simplify your life.
The app is a 1.13GB download, including the native Gemini Nano model. After installation, it requires access to several system permissions. You are presented with a very simple chat interface that reflects the experimental nature. COSMO is probably a test bed for future experiments, not anything intended for consumers.
The Application has the following “Skills” or capabilities:
- List Viewer: Automatically prompts you to save lists.
- Document author: If I say you need to prepare a document, write a letter, or summarize something, offer to prepare a document for me.
- Calendar Event Proposer: If I’m discussing plans or planning with someone and agreeing on a time, offer to schedule it on the calendar.
- Browser agent: Offer to automate tasks using Mariner.
- Add a timer: If I tick a timed task, suggest creating a timer in the clock app.
- Deep Research: Offer to complete in-depth research on the topic for me if I discuss a complex research need that requires multiple sources to answer and where a full report would be helpful.
- Fast Photo Search: If I mention a photo I took and want to share with someone, offer to find the photo for me so I don’t interrupt the conversation.
- Google: When I have a question that can be answered quickly with a web search, offer to find the answer for me.
- Jargon Definitions: If I come across complicated jargon or an acronym, explain what it means to me.
- Provide insight: Offer ideas and suggestions to help my curiosity when I’m looking for information or ideas.
- People Understand: Provide context about people.
- Event Understanding: Provide context about events.
- Remember: Show me the things I’m trying to remember.
- Summary of the conversation: Summarizes recently finished conversations when you switch context.
The Settings page has a “Runtime Model” menu with three options:
- Hybrid: Hybrid (PI when online, Nano offline)
- Only PI: Use Server PI only
- Nano only: Use only Native NanoApp
It’s not clear what the “PI” stands for, but the local offering is likely the Gemini Nano.
Other features allow you to set voice compatibility and allow screen access.
This feels like a premature or random release ahead of Google I/O 2026 later this month. Not intended for consumers.
