What people usually ask before using it
What is the 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, Omni Flash or Seedance, among others. No sign-up required. It's the same tool known in Spanish as “Genio del Prompting”.
Do I need to sign up or pay to use it?
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.
What gets stored from the text I write?
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, so you shouldn't include personal data or confidential information.
Which AI models does it work for?
It covers five types of result —text, image, video, agent and SEO for ZimmWriter— and within each one the most-used models, with 29 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.
What are each model's options for?
They're the settings that actually change the prompt for that specific model: the effort level in Claude, the search preset in Perplexity, the duration and resolution in Omni Flash, 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.
Want something like this for your business?
I built this tool end to end myself: interface, backend, cost control and legal layer. I do the same for agencies and hotels that want to automate processes with AI.
