Explain This Prompt: See What Each Line Is Doing
Paste any AI prompt and get a plain-English breakdown of the role, task, constraints, and format — so you can tell why it works or why it failed.
A long prompt can look professional and still be doing nothing useful. One line sets the role. Another repeats the task. A third contradicts the format. Explain This Prompt annotates those parts in plain English so you can see the structure instead of guessing.
What you get back
- The role: who the model is supposed to be.
- The task: the one job you actually asked for.
- Constraints: length, tone, facts it must not invent.
- Format: bullets, table, script, or image directions.
- Tips on lines that are vague, duplicated, or fighting each other.
Rough drafts and polished prompts both work. This is the tool to use when someone hands you a prompt and you need to know whether to trust it before you paste it into ChatGPT, Claude, Gemini, or an image model.
How to use the breakdown
- Paste the full prompt, including negative lines if it is an image prompt.
- Read the role and the task first. If those two disagree, the rest of the prompt will not save it.
- Mark constraints that are wishes (“be creative”) versus rules (“under 120 words, no invented numbers”).
- If a section is weak, send the same text to the Prompt Enhancer or Prompt Critique.
Learning from prompts that already work
Paste a prompt from the library into the explainer before you edit it. You will see which lines lock identity, format, or tone. Keep those. Change only the blanks that are meant to change. That is safer than rewriting a working prompt from memory.

FAQ
Can I paste a Midjourney or Gemini image prompt?
Yes. Paste the full text, including style and avoid lines. The breakdown covers those the same way it covers a writing prompt.
