Prompt Generator: Precise Prompts for ChatGPT, Claude and Gemini
Chat shortcut: /prompt
Describe in one or two sentences what you want to achieve. The prompt generator turns it into a detailed prompt that you use in ChatGPT, Claude or Gemini, or try out here in a new chat.
No Sign-Up
An idea becomes an instruction the AI understands
A brief request leaves a lot open: "Write me a newsletter" does not say for whom, how long, in what tone and with what goal. The generator does not ask these questions, it answers them: it adds role, goal, audience, context, format and rules, and marks in square brackets where you should still fill in details.
You type in your idea, decide whether you want one prompt or three variants, and whether the prompt should be written in your language or in English. The result is a finished text to copy, whether you use it in ChatGPT, Claude or Gemini.
You can also run the prompt here: end generator mode via the bar in the input field or open a new chat, paste the prompt and choose the model. As long as generator mode is active, every message is turned into a prompt again.
How it works
- 1

Write in one or two sentences what the AI should do for you, for example "Cover letter for a position as a registered nurse".
- 2
Choose the result
Decide between one worked-out prompt or three variants to compare.
- 3
Set the language
Have the prompt generated in the language of your input, or choose English.
- 4
Use the prompt
Copy the prompt into your AI tool, or end generator mode (or open a new chat) and run it here; fill in the placeholders first.
Typical uses
Writing
"Newsletter for regular customers" becomes a prompt with audience, length, tone and call to action.
Learning and explaining
"Explain photosynthesis to me" becomes a prompt with level, examples and quiz questions.
Code and tech
"Script for renaming files" becomes a prompt with language, environment, edge cases and output format.
Analyses and summaries
"Summarize this report" becomes a prompt with audience, length, structure and a placeholder for the text.
Role play and training
"Practice a job interview with me" becomes a prompt with role, flow and feedback rules.
Good to know
- Result: one prompt or three variants; language the same as your input, or English.
- The generator adds role, goal, audience, context, format and rules, and sets placeholders for your details.
- Runs as a chat tool with the model you choose in the input field; a default model is preset. You run the finished prompt in a normal chat with any available model.
- Usable without sign-up; usage per reply depends on model, input and output and thinking phase, starter allowance also as a guest. Running the prompt is a separate request and costs extra.
- Characters per message: as a guest without credit 1,000, with an account without credit 10,000, with credit or a subscription no plan limit; for the generator a few sentences are usually enough.
- No prompt database: every prompt is freshly generated from your description.
Frequently asked questions
What makes a good prompt?
A good prompt names role, goal, audience, context, the desired format and rules, such as length or tone. The generator adds exactly these building blocks for you and sets placeholders where your details are still missing.
How do I run the prompt?
The generated prompt is plain text for all common text models: paste it into ChatGPT, Claude, Gemini, Grok or DeepSeek. Here on ChatX, first end generator mode via the bar in the input field or open a new chat; otherwise your message is turned into a prompt again.
What do three variants give me?
You get three different wordings of the same task, for example a concise one, a detailed one and one with a role assignment. Choose the one that fits or combine parts of them.
Why can I choose English as the language?
For English-speaking teams, templates or models you work with in English, even if you typed your idea in another language. If the reply should still come in your own language, write that as a rule in the prompt; the language setting only determines the language of the prompt.
Do I still need to adjust the prompt?
Usually only at the placeholders: insert numbers, names, examples or your source text. The more specific the prompt, the more useful the reply.
What does the generator cost?
It runs as a chat request and is billed by actual usage: by model, input and output and any thinking phase. Running the prompt later is a separate request. A starter allowance is available without sign-up.
Is my input stored?
The request goes to the provider of the selected model; what it stores is governed by its terms. The chat stays in your history until you delete it; guest histories without a purchase are deleted after 30 days without a visit. Do not enter passwords or sensitive personal data in the description.
