PromptShelf — AI Prompt Library

Save, organize, search, customize, and reuse AI prompts. Private by design: your library stays in your browser.

PromptShelf is a personal library for the AI prompts you use again and again. Stop searching through old chats or rewriting the same instructions. Keep your best prompts organized, find them quickly, customize templates, and copy the result whenever you need it. FEATURES • Start with 15 ready-to-customize prompt templates for software engineering, AI and machine learning, careers, writing, and productivity. • Create, edit, tag, categorize, favorite, and search your prompts. • Customize template variables such as {{topic}} or {{code}} before copying a prompt. • Import and export your library as a JSON backup. • Open a full workspace to manage your prompt collection. PRIVACY Your prompt library is stored in Chrome's local extension storage. PromptShelf does not send your prompt content to a developer-operated server or an AI provider, and it does not read your browsing history or active tab contents. You choose which prompts to copy into other applications. Keep an exported backup before clearing browser data or uninstalling the extension. No account is required. OPTIONAL SUPPORT Enjoy using PromptShelf? You can voluntarily support its development through Ko-fi: https://ko-fi.com/ashutoshdev The donation is optional. Core extension features do not require payment.
