Paste this into ChatGPT, Claude, Gemini or any other assistant. Nothing here is sent to a model.
The AI Prompt Generator turns a rough idea into a structured prompt by walking you through the parts a good prompt actually needs — role, task, context, output format, tone and constraints — then assembling them into a clean, sectioned prompt you can paste into any assistant.
Most disappointing answers come from prompts that left the model guessing. This builder walks you through the parts a good prompt actually needs — who the model should be, what you want done, the background it cannot infer, the shape the answer should take, the tone, and the things it must not do — then assembles them into a clean, sectioned prompt you can paste into any assistant.
Structure is doing the work here, not magic words. Naming a role narrows the vocabulary the model draws on; stating the output format stops you reformatting the answer by hand; giving one worked example is usually worth more than another paragraph of instruction. Presets cover common jobs — writing, code review, summarising, extracting data — and every field stays editable, so treat them as a starting point rather than a template to submit as-is.
Role, task, context, output format, tone and constraints are prompted for separately, so nothing important is left for the model to guess.
Naming a role narrows the vocabulary the model draws on, and stating the output format saves you reformatting the answer by hand.
Writing, code review, summarising and extracting data give you a starting point instead of a blank page.
Presets fill the fields rather than locking them, so the prompt ends up yours.
The output is plain structured text, so it pastes into Claude, ChatGPT, Gemini or anything else.
Choose the job you are doing, or start from blank if none of them fit.
Say plainly what you want produced. This is the one field worth spending time on.
Give the background the model cannot know, and list what it must avoid or must include.
Copy the finished prompt and paste it into ChatGPT, Claude, Gemini or any other assistant.
Specificity about the output. A clear task, the context the model cannot infer, the exact format you want back, and one example of a good answer will outperform any clever phrasing.
The structure transfers well, because all of them respond to a clear role, task and format. Fine details such as how much length to ask for differ, so treat the generated prompt as a strong first draft and adjust from the answers you get.
Usually yes. One or two examples of the output you want is the single most reliable way to control format and tone, and it costs far fewer words than describing the same thing in prose.
No. The builder assembles text in your browser. Nothing is sent to a model, an API or a server by this page.
