Prompting Genie

It's a free web tool that turns an idea written in two sentences into a well-structured prompt tuned for the specific AI you're going to use: ChatGPT, Claude, Gemini, Grok, Perplexity, DeepSeek, Qwen, Midjourney, Nano Banana, Sora or Veo 3, among others. No sign-up required. It's the same tool known in Spanish as “Genio del Prompting”.

No. It's free and works with no account, no email and no key of any kind. There's only a daily usage limit to keep the tool sustainable.

The goal, the context, the generated prompt and the rating are stored anonymously for 12 months, to improve the tool. The IP address is not stored. The text is processed with Google Gemini which, on the free tier, may use it to improve its models, so you shouldn't include personal data or confidential information.

It covers four types of result —text, image, video and agent— and within each one the most-used models, with 27 combinations in total and model-specific options. If your model isn't on the list, the Generic option returns a prompt valid for any AI.

They're the settings that actually change the prompt for that specific model: the effort level in Claude, the search preset in Perplexity, the variant and duration in Veo 3.1, or the style parameters in Midjourney. Image also opens up the 12 art-direction blocks, and video the seven-decision CASCADE sheet: whatever you leave empty the tool decides for you, and it tells you which ones it made up. All of it is optional: if you don't touch anything, the prompt is generated anyway.
