Why Prompt Scaffold?
Most people know the theory of a good prompt but still write inconsistent ones in practice. Prompt Scaffold turns the framework into a guided form — so you never miss a field again.
Key Features
- 📝 Structured Fields: Dedicated inputs for Role, Task, Context, Format, and Negative Constraints — the five pillars of a great prompt. Each field shows a live character count (top-right corner) so you always know how much you’ve written.
- ⚡ Live Preview: See your assembled prompt update in real-time as you type.
- 🔢 Token Estimate: The preview panel displays a running token count (e.g.
~245 tokens), giving you a rough idea of how much of an AI model’s context window your prompt will use. Rule of thumb: 1 token ≈ 4 characters. - 📋 One-Click Copy: Copy the finished prompt to your clipboard instantly.
- 🗂️ Built-in Templates: Load proven starter templates for common use cases like writing, coding, and email drafting.
- 🔒 100% Private: Everything runs in your browser — nothing is sent to any server.
How to Use
- Select a Template (optional): Choose a preset to pre-fill the fields as a starting point.
- Fill in the Fields: Define the AI’s Role, what the Task is, relevant Context, your desired output Format, and any Negative Constraints.
- Preview & Refine: The right panel assembles your prompt in real-time — tweak until it’s perfect.
- Copy & Use: Hit “Copy Prompt” and paste it directly into ChatGPT, Claude, or any other AI.
