Prompt Workspace | HTML5 AI Prompt Manager and Library

Prompt Workspace is a premium, offline-first workspace built to fix that — permanently. Organize, refine, test, and reuse every AI prompt you own, in one fast, modern, 100% local application. No sign-up. No server. No subscription. No data ever leaving the browser.

Built entirely with HTML5, CSS3, and vanilla JavaScript (ES6) — zero frameworks, zero build step, zero backend. Unzip it, open index.html, and you’re working in seconds.

Why Prompt Workspace?

If you write, test, or reuse AI prompts on a regular basis — for ChatGPT, Claude, Gemini, Midjourney, or any other model — you already know the problem:

Good prompts get buried and never found again
You rewrite the same instructions from scratch, over and over
There’s no version hist
