Need prompts tuned by model?
The free version gives you a good generic prompt. Prompting Genius PRO adapts it to the specific destination: text, image, video or agent, and within each one to the model you're using —ChatGPT, Claude, Gemini, Grok, Perplexity, Midjourney, Veo— with each one's specific options.
- 21 output-type × model combinations
- Options that actually change the prompt, not decoration
- 50 uses a day, on all your devices
What people usually ask before using it
What is the Prompt Improver?
It's a free web tool that turns a two-sentence idea into a well-structured prompt, ready to paste into ChatGPT, Claude, Gemini or any other AI. No sign-up required.
Do I need to sign up or pay to use it?
No. The free version works with no account, no email and no cost. There's only one optional paid version, Prompting Genius PRO, which tailors the prompt to the specific model you're going to use.
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. Your IP address is not stored. The text is processed with Google Gemini, so you shouldn't include personal data or confidential information.
How does the PRO version differ?
The free version returns a good generic prompt. Prompting Genius PRO adapts it to the specific destination —text, image, video or agent— and within each one to the model you're using, with model-specific options. It costs €9 a month and includes 50 uses a day.
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.
