The Prompt Field Guide
A prompt is the written instruction that tells an AI system how to act. Good prompts make AI answers clear and safe. Weak prompts cause vague or risky replies.
This free tool teaches you to spot the difference. Paste a practice prompt below. In about a minute you get a score and concrete fixes, based on the rubric ICX uses in client work. No sign-up needed.
