Build better prompts.
Every time.
A rule-based prompt engineering wizard that teaches you why each field matters — not a black box that wraps an AI call.
Pick your goal.
The simplest and most versatile framework. Define who the AI should be, what it should do, and how it should format the answer.
Clean labeled sections — works well with any AI model.
Fill in your prompt.

- The RTF framework (Role-Task-Format) gives you the three most impactful prompt levers in the simplest structure.
- Start filling in the fields above to see how each one strengthens your prompt. Every field you add reduces ambiguity.

Build clearer instructions for every AI model
Learn how this tool turns an early idea into a clear brief for ChatGPT, Gemini, Claude, Midjourney, and more.
What is an AI Prompt Generator?
Models such as ChatGPT, Claude, and Gemini respond better when they receive a clear role, enough context, a concrete task, and an expected format. This generator helps turn a one-line idea into an instruction set that covers those essentials.
Choose RTF for a concise brief, CO-STAR for a fuller communication plan, TAG for goal-oriented work, or APE when the purpose matters most. The wizard shows how each field contributes to the finished prompt and assembles it locally in your browser.
A transparent way to build prompts
The builder keeps the process visible: you can see the assembled prompt as you work, learn why each field matters, and choose formatting that fits the target model. It runs in the browser and can optionally use an API key you provide for refinement.
Saved prompts, model choices, before-and-after comparisons, and starter templates give developers, marketers, researchers, and creators a practical place to iterate without losing their work.
Supported Modalities: Text, Images, Video & Coding Prompts
Text prompts for Gemini and beyond
For blogs, emails, research, and analysis, define the audience, point of view, tone, and output format. These details give text models a useful frame for producing an answer you can use.
Image and art direction
Midjourney, Stable Diffusion, and DALL·E benefit from detailed subjects, composition, lighting, palette, camera language, and exclusions. Use the visual category to bring those directions together in one repeatable brief.
Video and motion direction
Video tools such as Sora, Runway, and Pika need a subject, setting, camera movement, lighting, and a sense of time. Describe how the scene begins, changes, and ends to make short clips and teasers more predictable.
Coding and refactoring briefs
For code, include the language, runtime or framework version, interfaces, success criteria, and edge cases. A structured brief is useful for functions, database schemas, tests, and refactors across coding assistants.
Everything You Need to Know About AI Prompting
Got questions about writing prompts, image generation, video prompting, or meta-prompting? Find clear answers below.
What is an AI prompt generator?
An AI prompt generator is a tool or wizard that helps users structure, format, and optimize text instructions for artificial intelligence models like ChatGPT, Google Gemini, Claude, and Midjourney. It uses proven frameworks like RTF, CO-STAR, and TAG to turn raw ideas into high-performing prompts.
What should I look for in a prompt builder?
Look for a tool that makes its structure clear, supports the models you use, and lets you review the final instruction before copying it. Local processing and optional refinement with your own API key are useful privacy and control features.
How do I write a good prompt for AI?
To write a good prompt for AI: 1) Define a clear Role (e.g. Senior Copywriter), 2) Provide Context, 3) Specify the Task, 4) Set Constraints (length, tone, style), and 5) Declare the exact Output Format (Markdown headers, XML, JSON, bullet points).
How to write a prompt for an AI video generator?
To write a prompt for an AI video generator (like Sora, Runway Gen-2, or Pika): 1) Describe the core subject and setting, 2) Specify camera dynamics (pan, tilt, zoom, drone shot), 3) Define lighting and mood (golden hour, volumetric glow), and 4) Detail movement pacing and frame rate expectations.
How to prompt an AI image generator or AI art generator?
To prompt an AI image or art generator (Midjourney, DALL-E 3, Stable Diffusion): combine subject details ("futuristic cyberpunk city"), art style ("photorealistic, octane render"), lighting & lens settings ("85mm lens, volumetric lighting"), and parameters like aspect ratio (--ar 16:9) and negative prompts.
How to use an AI image generator with a text prompt?
To use an AI image generator with a text prompt, enter a descriptive text string starting with your subject, followed by visual style cues (medium, camera angle, lighting), and negative keywords. Our AI prompt generator structures these fields into weighted syntax ready to copy into Midjourney or Stable Diffusion.
Can I use a prompt generator for any AI model?
Yes! A quality prompt generator formats outputs for any model target. For example, ChatGPT prefers Markdown headers (## Role, ## Task), Claude excels with XML tags (<role>, <task>), and Gemini responds best to bold parameter blocks (**Role:**).
What is meta-prompting?
Meta-prompting is the technique of using an AI model to write, critique, optimize, or refine prompts for another AI model (or itself). Instead of manually crafting a prompt from scratch, meta-prompting uses AI intelligence to build structured system prompts tailored for optimal execution.
Are there free AI prompt tools?
Yes, there are completely free AI prompt tools available. Our AI Prompt Generator is 100% free and open-source with zero sign-ups, subscriptions, or paywalls. All prompt assembly and framework wizards execute locally in your browser.
How to prompt AI art generator free online?
You can generate structured image and art prompts online for free using our built-in Image & Visual category wizard. Select the "Image / Visual" category, fill in your subject, style, lighting, and camera angle preferences, and copy the assembled prompt straight into free image generators like Bing Image Creator or Leonardo AI.
