Hi @sips,
You would need a collection of the words ( I think you mean quotes right? ) or you can search for an API to connect as a Custom action or an external collection and show random ones!
A example : Some Tips and Tricks by this Semi Noob! 😅 ( Tip No 9 )
To show them when they first open the app you can make a Fake Home screen and add the text component there and make that screen as the Home Screen!
A example : Showing a screen at startup only - #5 by dilon_perera
For send them as a notification you can use the Trigger Notification action!
Thank you
