17 prompts for building AI apps in Voiceflow

Prompts help guide machine learning models towards specific outputs. They're kind of like nudges in the right direction.

When it comes to conversational AI, prompts are particularly important. They help focus language models to generate specific responses to questions or statements. By using the right prompts, we can make sure our AI chatbots and voice assistants are responding accurately and appropriately—and that we’re delivering more sophisticated and engaging user experiences.

If you’re new to prompts and prompt chaining, we encourage you to dive in, experiment, and see what’s possible. To help, we’ve rounded up 17 of the best prompts that you can use to create AI apps in Voiceflow.
