What makes a prompt score well
Strong prompts are not about magic words. They give the model what any capable colleague would need: a clear task, the context around it, the shape of the answer you want, the limits to stay inside, who it is for, and a sense of what good looks like. The grader checks for each of these so you can see what to add. Writing a precise prompt, then judging and correcting the output, is exactly the kind of work that separates people who get real value from AI from people who just paste and hope.
Frequently asked questions
What is a good AI prompt?
A good prompt states the task clearly, gives context, sets the output format, adds constraints, names the audience or tone, and includes enough detail. The grader checks your prompt against each of these and shows what is missing.
Is the AI prompt grader free?
Yes. It is completely free, runs in your browser, needs no account and shows no ads. Your prompt is never uploaded anywhere.
How is the score calculated?
The tool checks your prompt for eight elements of effective prompting (clear task, context, role, output format, constraints, audience, examples and enough detail) and scores the share you include. It is a writing guide, not a prediction of the model's answer.
Does using AI well matter for hiring?
Increasingly, yes. How a person works with AI, including how they prompt, review and judge its output, is a measurable capability. Answerr measures this and issues a verifiable AIQ credential.
