Hi again 🙂 you can use an execute code card with a bit of code

const random_index = Math.floor(Math.random() * workflow.options.length)
const random_sentence = workflow.options[random_index]
workflow.random_sentence = random_sentence

something like that

Thanks for this! Where would you store the array with the 10 sentences in that case?

Amazing!

and if your sentences are not willing to change within a conversation,you can setup directly the sentences in it
