How it works
Three steps between your idea and a prompt that's ready to paste into any AI tool.
Describe your idea
Type what you want in plain words — a thumbnail, a logo, a caption, an image, anything.
Pick your AI models
Choose which tools you're generating for. Each one gets a version tuned to its own style.
Copy & use
Paste the output straight into ChatGPT, Midjourney, Gemini or wherever you need it.
Built for every major AI
One input, tuned output for each model's own strengths and prompt style.
Why the same prompt doesn't work on every AI
ChatGPT, Gemini, and Claude follow conversational instructions — they read your goal, your context, and your formatting requests. Image models like Midjourney and Flux don't "understand" instructions the same way: Midjourney rewards a comma-separated, keyword-and-parameter style, while Flux responds better to full descriptive sentences. Reusing one prompt everywhere is the single biggest reason people get disappointing results from AI tools — which is exactly what this AI prompt generator is built to fix, by writing a version tuned to each model automatically.
Quick prompt-writing tips
- Be specific about the output, not just the topic — state the goal, the format, and the length you want.
- Give chat models a role when it helps ("act as an experienced copywriter") to shift tone and quality.
- For image prompts, order matters — put the subject first, then style and technical details.
- Iterate instead of starting over — use the Improve tab to make an existing prompt more detailed, cinematic, or concise.
