A typing delay is a short pause before a chatbot responds to you. It's the few seconds you wait after sending a message. This delay makes it feel like someone is actually typing out the response.
Typing delays are useful for a few reasons. They make the conversation feel more natural, like you're talking to a real person instead of a robot. The delay also gives you time to expect that a response is coming, instead of an instant reply.
And it gives the chatbot a quick moment to process what you said behind the scenes. Most chatbots let you adjust how long this typing delay lasts, but just a couple seconds is best.
