As of April 2025, the frontier has moved to AI Agents and Agentic AI. And yet, the ChatGPT interface remains impractical to organize past conversations or make sense of one’s most used prompts.
I find myself storing my prompt templates in various text files, google docs, or copy-pasting from previous prompts. It’s all a big mess and a waste of time. So I needed a tool to management my prompts.
To solve this problem I’ve created Prompt Library, a web-based prompt library and composer. The tool lets you create, edit, search, and tag your prompts, insert variables and placeholders, etc. All data is stored locally for more privacy, and you can export your prompts as a JSON file. You can check out the full list of feature on the GitHub project page.
Future developments will include a way to store the history of changes made to a prompt, and compare different versions, and possibly to be able to store “prompt paths,” that is to say how to represent a graph of prompts used in sequence for more complex tasks.
