Google released an experimental AI assistant application called COSMO for Android devices, which has since been removed from the Play Store due to an accidental launch. The app, which is 1.13 GB in size, was designed to enhance daily productivity by organizing schedules and answering complex queries. COSMO features include a list tracker, document writer, calendar event suggester, browser agent, timer suggestions, deep research capabilities, quick photo lookup, web search functionality, jargon definitions, insights provision, context understanding for people and events, recall assistance, and conversation summarization. It offers three settings: Hybrid, PI Only, and Nano Only, with the latter two indicating different processing methods. The app also includes voice match and screen access features but is not intended for the general consumer market.
