Build a reusable prompt library
Good prompts are worth keeping, and a scattered collection in notes and chats is hard to reuse. This tool lets you create, tag, search and export reusable prompts, stored locally in your browser, so your best prompts are organised and to hand.
Why a prompt library helps
As you work with AI, you develop prompts that work well, and re-deriving them each time wastes effort. A library lets you save the good ones, tag them by purpose, and search to find the right one when you need it, turning ad hoc experimentation into a reusable asset. Being able to export means the library is portable rather than trapped. Because it stores locally in your browser, your prompts, which can encode real know-how, stay private on your machine rather than on someone else’s service.
Your prompts, organised
The tool runs entirely in your browser, so nothing you paste, prompts, outputs or documents, is uploaded, which matters when the input is sensitive AI data or your own content.
