Google has recently been busy playing catch-up with various other companies. They worked hard to make Gemini a success such as offering Gemini Advanced for users, introducing Gemini 1.5 Pro for developers as well as applications for users to use. Most recently, Google is reported to also integrate AI on the Play Store.
On the Google Play Store, listed app summaries are now displayed with AI-generated text. This AI will explain what important features the developer wants to emphasize. Since it is AI generated, it is very likely that the text displayed for all users will be different but with the same context.
Google has already used the same AI system on their FAQ page. Now more or less the same feature is expanded to details and application summaries. This feature is still limited to a few users only, not sure when Google will introduce it to the public.
