Vague prompt
Make me a to-do app.
No language, no features, no level, no format. The AI has to guess everything, and you won't know why it chose what it did.
PROMPT LAB
Write the prompt before you ask the question.
Describe your project, then let a free AI polish your prompt into something clear and ready to paste into Claude, ChatGPT, or Gemini.
Prompt generator
Fill in what you know. The preview updates as you type. When you're ready, polish it with AI.
Before and after
Same idea. The second prompt gives the AI something to work with.
Structured prompt
Goal: Build a to-do list web page.
Experience: Beginner. Use simple words.
Requirements: Add, complete, and delete tasks. Keyboard friendly.
Constraints: HTML, CSS, and JavaScript only. One file.
Output: Full code with comments, then explain each part.
Clear goal, clear limits, and a request to explain. You get code you can read, test, and change.
How to write better prompts
Six habits that improve almost every answer you get.
State one clear goal
Say what the finished thing does. "A page where visitors can filter a list" beats "a cool website".
Give context
Mention your experience level, what you've tried, and where you're stuck so the answer fits you.
List requirements and limits
Name the language, the features you need, and what to avoid, such as libraries or frameworks.
Ask for the output you want
Request full code, a plan, or a tutorial. Say whether you want comments in the code.
Ask for an explanation
End with "explain what each part does". If you can't explain it, you don't own it yet.
Test, then follow up
Run the code. If something breaks, paste the exact error message and ask what it means.
