What is an AI prompt library?
An AI prompt library is a saved set of instructions you reuse with a chat assistant, rather than typing a fresh request each time. Each prompt names the task, the format you want back, and the details to fill in, so the same prompt gives usable output on a Monday and on a Friday.
A library helps most once you use an assistant several times a week. The gap between a one-line request and a written prompt is usually the difference between output you rewrite entirely and output you edit lightly. Saving the good ones means you stop rebuilding the same instructions from memory.
