About AI Prompt Generator
The AI Prompt Generator assembles a well-structured prompt from the building blocks of effective prompting: role, task, context, audience, tone, output format, length, constraints and examples. Fill in the fields and the finished prompt composes itself live, with a character and approximate token count.
Six ready-made templates — blog post, coding, marketing, summary, email and image generation — prefill a sensible role and task so you start from proven structure instead of a blank box. Eight tones and formats from bullet points to JSON to step-by-step cover most output needs, and each constraint line becomes its own bullet.
The prompt is built entirely in your browser by deterministic composition — no AI call is made and nothing is uploaded. Copy the result into any chatbot or model interface, or download it for your prompt library. Free, no account.
How to use AI Prompt Generator
- Optionally start from a template: blog post, coding, marketing, summary, email or image.
- Describe the task — the one required field — being as specific as you can.
- Add the supporting blocks: role, context, audience, tone, output format and target length.
- List constraints one per line (each becomes a bullet) and paste an example of the style you want.
- Review the live preview with its character/token estimate, then copy or download the prompt.
