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 history when an edit makes a prompt worse instead of better
• Reusable variables, personas, and formats live in your head, not in a system
• Sharing a “prompt library” with a client or team means a messy Google Doc

Prompt Workspace turns that chaos into a structured, searchable, analyzable library — and because it runs 100% client-side, it’s private by design and suitable for white-label customization, internal business tools, or client projects.
