AI Prompt Builder — Turn a Brief into a Clear Prompt

Turn a rough brief into a structured prompt for a writing or coding assistant. The builder arranges your own instructions; it does not contact an AI model or generate an answer for you.

Calculations run in your browser. No account or API key is needed.

## Task
Write a 60-second explainer about keeping a small balcony garden.

## Audience
Beginners living in apartments

## Reference material
The balcony gets morning sunlight. There is room for three pots. Herbs are the first project.

## Requirements
Use plain language. Include one small action the viewer can try today. Do not invent facts.

## Output format
Outline with headings

## Checks
Check the result against the task and requirements. Flag missing facts or uncertainty. Do not invent citations.

How to use this tool

  1. Describe one concrete task and its intended audience.

  2. Add the source notes and requirements that the answer must follow.

  3. Choose an output format, build the prompt and copy it into your preferred assistant.

A brief you can review

The result separates the task, audience, reference material and requirements with Markdown headings. This makes omissions easy to spot before you send anything. For the balcony example, replace the sample notes with your actual space and light conditions; keep observations separate from assumptions.

Improve the next attempt

Try the prompt on a representative example, check the answer, then change the part that was unclear. A requested JSON format is an instruction, not schema validation. If software consumes the answer, use the provider’s structured output feature and validate the returned data.

Common questions

Does this choose the best AI model?

No. It creates an editable prompt that you can use with a text assistant. It makes no model-specific accuracy promises.

What if I do not have source notes?

Leave that field empty. The prompt will ask the assistant to identify missing information instead of treating absent details as facts.
