AI Prompt Checker

The AI Prompt Checker reviews a prompt and flags common weaknesses — missing role or persona, no output format, vague wording, or excessive length — with concrete suggestions. All analysis is heuristic and runs in your browser; nothing is sent anywhere.

Findings
  • Paste a prompt to see suggestions.

Before you spend a model call on a weak prompt, lint it. The checker scans your prompt for the failure patterns that most often produce disappointing answers — no role, no output format, vague wording, or a prompt so long the model loses focus — and tells you exactly what to tighten.

How to use the AI Prompt Checker

  1. Paste the prompt you want to review.
  2. Read the findings — each flags a specific weakness with a suggestion.
  3. Fix the issues and re-run until it comes back clean.

Common use cases

  • Sanity-check a prompt before using it in production or a script.
  • Learn what makes a prompt effective by seeing what's flagged.
  • Review prompts contributed by a team against a consistent bar.

Tips

  • A clean result isn't a guarantee of quality — it means the common structural pitfalls are avoided.
  • Pair it with the Optimizer: check first, optimize, then check again.

Frequently asked questions

Is anything sent to a server? +

No. The prompt is assembled entirely in your browser from your inputs — nothing is uploaded, and no AI API is called. It is a deterministic builder, so the same inputs always produce the same prompt.
