how can I make it so that if it detects that the user said a specific word, it leads the user to another node. For example I'm making a bot for my school and I want to make it so that if the user says the word period, the bot will make a single choice asking if it wants the schedule for the normal or late arrival schedule.

If you haven't already, you might want to try an "Intent". Here's a short YouTube video about it: And the documentation: https://botpress.com/docs/cloud/studio/library/#intents

you can also just use a expression card and put the label as something like "if the input has the word if in it" and then connect to another node. I personally like this more then intent cards.
