Why use a Prompt Library?
Engineering the perfect AI prompt is often a process of trial and error. Scatter-shot notes or past chat histories are hard to search and reuse. A dedicated prompt library allows you to build a structured 'second brain' for your AI interactions. By abstracting repeatable parts into variables, you turn one-off prompts into reusable templates that yield consistent results across different projects.
