Fallback

If your AI Agent doesn't recognize the user's intent, it activates the fallback trigger. This can occur in the following situations:

• The AI Agent recognizes the intent with a confidence level below the threshold you have set.
• You have not connected the intent to a trigger that matches the dialogs you have already set up. This can be done for intents like #offtopics.
• The AI Agent does not recognize an appropriate answer to a question (wrong type or entity).

Multilevel dialog

You can also use the fallback as a child node in a dialog. This means that the AI Agent activates this trigger only when it is already inside the dialog of a parent node.

When the fallback is a child node, if the user types something that the AI Agent cannot understand within a dialog, the message it gives the user is different than when the user is not in the dialog.
