AI Code Prompt Generator
Turn a vague coding request into a prompt that gets working code.
Coding models do best with specifics. Prompt Helper adds the language and framework, inputs and outputs, constraints and edge cases that a good request needs.
No sign-up needed to try. Limits are on the pricing page.
See the difference
a function that checks if an email is valid
Task: write a function that validates an email address. Language: JavaScript (ES2022), no external libraries. Input: a single string. Output: a boolean. Rules: require one @, a non-empty local part, and a domain with at least one dot; reject spaces. Edge cases: empty string, leading or trailing spaces, multiple @ signs, very long input. Style: small, readable function with comments only where the logic is not obvious. Also provide: five test cases (three valid, two invalid) with expected results.
An illustrative example. Your result will depend on what you type.
What you get
Inputs, outputs and types
The shape of the data going in and out is stated, not guessed.
Constraints and edge cases
Libraries, versions and tricky inputs are listed so the answer handles them.
Tests requested up front
Asking for examples and test cases makes the result easier to check.

Questions
Which languages does it support?
You describe the language in your request, and the generator keeps it in the prompt. It is not limited to one language.
Does it write the code for me?
No. It writes a better prompt for you to give to a coding model. You paste the result into the tool you already use.
Can I add my own context?
Yes. Use Memory to keep notes about your stack, and edit the prompt before you copy it.
Is it free?
You can try it without signing in. Limits are shown on the pricing page.
