Prompt Coverage Checker
Check whether your prompt gives an AI model enough context, clarity, constraints, and structure to deliver a great response — and find the gaps before you paste it into ChatGPT, Claude, Gemini, or Perplexity.
Paste your prompt below. The checker analyzes it across five dimensions — context, objectives, constraints, input completeness, and structure — scores coverage from 0–100 with a fully transparent formula, flags missing and weak elements, and generates prioritized recommendations plus a branded PDF report. No account, no subscription, no paid APIs.
