What is Fallback?

Fallback PromptDialog refers to a backup plan used when the system encounters inputs it cannot understand or process. It helps the system deal with the following situations:

  • When users ask unrelated questions (Dialog flows & Faq not include the input), the system responds with something like “I don’t know.”
  • If the user’s input is unclear or ambiguous, the system asks for more specific information.
  • When the system is uncertain about a response, it may indicate its uncertainty.
  • In the case of technical issues or errors, the system explains the problem to the user and may offer solutions.

PromptAI supports Fallback mode

  • webhook
  • action

PromDialog also support to hand over the default reply to a third-party API for processing

Fallback with Default

When the above three methods fail, we will use the default method to handle the fallback, which is the text filled in the figure below. fallback-text
