AI Prompt Builder
Build structured, high-quality prompts for ChatGPT, Midjourney, DALL-E, and Stable Diffusion. Copy, enhance, and save your best prompts.
How It Works
Prompt engineering made simple with structured templates.
Structured Templates
Each platform has a purpose-built template. ChatGPT uses role-task-context-format. Midjourney uses subject-style-lighting. No more guessing the right structure.
Smart Suggestions
Dropdown menus come pre-loaded with proven options for roles, styles, lighting, camera angles, moods, and more. Pick and customize from the best prompt engineering practices.
Save & Rate
Build a personal library of your best prompts. Rate each one 1-5 stars so you can quickly find what works. Everything stays in your browser with localStorage.
Frequently Asked Questions
Common questions about prompt engineering and this tool.
Select an AI platform, fill in the structured form fields, and the tool assembles a complete prompt using proven prompt engineering frameworks. You can then copy, enhance, or save it.
ChatGPT uses role-task-context-format. Midjourney uses subject-style-lighting-camera-mood. DALL-E uses descriptive style-subject-setting. Stable Diffusion uses positive/negative prompt pairs.
Yes! Your prompts are saved to your browser's localStorage. Rate each prompt 1-5 stars, copy, or delete them. Data stays on your device and is not uploaded anywhere.
The Enhance button applies prompt engineering best practices: adds specificity, replaces vague words with precise ones, structures the prompt correctly, and adds relevant context or constraints.
Token count is estimated using: words × 1.3 ≈ tokens. This is a rough estimate — actual tokenization varies by model. Use it as a general guideline for staying within context limits.
