AI Prompt Generator
Free, no sign-up. Your words never leave this page.
Paste it into ChatGPT, Claude, Gemini, Midjourney, Veo, Kling or any AI tool. Edit any word before you use it.
How does the AI prompt generator work?
Most bad AI answers come from vague prompts. A good prompt names five things: a role, a task, an audience, a tone, and an output format. This tool assembles those five parts for you. Type what you want in plain words, answer a few one-tap questions, and you get a structured prompt that tells the AI exactly what to do instead of making it guess.
Everything runs in your browser. No sign-up, no API key, no cost, and your words are never sent to a server. The prompt strength meter shows what is still missing, so you can fill the gap before you copy.
Three prompt types in one tool
Text prompts for ChatGPT, Claude and Gemini
Write emails, blog posts, social captions, code help, stories, business plans and study notes. Choose the task type and target model, and the tool formats the prompt with role, task, audience, tone, length and output format.
Image prompts for Midjourney, Flux and DALL-E
Describe the subject, pick a style, lighting, camera and mood, and get a single descriptive sentence that image models follow well. Specific details about texture, light and framing move the result more than flowery adjectives.
Video prompts for Veo, Kling and Runway
Video models work best with one subject, one action and one camera move. This tool follows that pattern: subject plus action plus place plus light plus camera move plus style plus mood. A 5 to 10 second clip should carry one clear shot, not three.
Tips for better prompts
- Lead with the goal, not the topic. “Write a launch email” beats “email about our feature”.
- Name the audience. The same request for beginners and experts needs different answers.
- Ask for the format you want: bullet list, table, email, script, or step-by-step guide.
- For video, use one camera move only. Asking for three moves at once confuses the shot.
- For images, name the lens and light. “85mm lens, golden hour” changes the result completely.
Frequently asked questions
Is the AI prompt generator really free?
Yes. It is free, with no sign-up, no credit card and no daily limit, because it builds prompts with templates in your browser instead of calling a paid AI model.
Which AI tools do the prompts work with?
The text prompts work with ChatGPT, Claude, Gemini, DeepSeek and similar chat models. Image prompts work with Midjourney, Flux, Stable Diffusion and DALL-E. Video prompts work with Veo, Kling, Runway, Pika and Luma.
Do you save my prompts?
No. Everything runs in your browser. Nothing you type is sent to a server or stored.
Can I use the generated prompts commercially?
Yes. The prompts are yours to use anywhere, including client work.
Why does my prompt have a strength score?
The score counts how many of the five key parts you filled: task, audience, tone, format and goal. A prompt with all five parts filled gives the AI far less room to guess.
