Google Trends: Google briefly lists COSMO AI assistant on Play Store, pulls it down after accidental release

Google appears to have briefly exposed an unreleased AI app called COSMO on the Play Store, before taking it down within hours. The app is believed to be an experimental “test lab” project from Google Research that wasn’t meant for public access yet. Despite its short appearance, it has already gained traction on Google Trends, recording around 20,000 searches in the past 20 hours.
