Is My Prompt Clear Enough?
Answer the question directly: a clarity score plus the specific reasons a prompt reads as unclear — vague terms, unstated objective, missing specifics.
Prompt Readability Checker
Diagnose a prompt before you send it: explainable scores for clarity, ambiguity, specificity, and structure, with observations that name where it is vague.
Overview
A prompt can read fine to its author and still be ambiguous to the model. This checks one before it ships, scoring four axes — clarity, ambiguity, specificity, structure — and explaining each score, then listing observations that point to where clarity may suffer. It loads a reasonably clear prompt so you can see a healthy diagnosis. Crucially, it is read-only: it names the problems and changes nothing. To clean, rewrite, or reshape the prompt, it points you to the right tool.
How to use this resource
-
Paste the prompt
Analyzed in your browser — your prompt is never modified.
-
Read the four scores
Clarity, ambiguity, specificity, structure — each explained.
-
Act on the observations
They name where it is vague; the fixing happens elsewhere.
Why This Works
- Four explainable scores turn a vague feeling into a concrete diagnosis
- Observations locate the problem instead of just flagging a number
- Read-only by design — it diagnoses, leaving the treatment to you
Best for
- Checking a prompt before sending it
- A clarity read-out across four axes
- Catching ambiguity early
Not for
- Cleaning the prompt — that's the Prompt Cleaner
- Rewriting it stronger — that's the Prompt Rewriter
FAQ
What four things does a prompt readability check measure?
Clarity, ambiguity, specificity, and structure — each scored and explained. The healthy sample here shows Clarity 90, Ambiguity 100, Specificity 50, Structure 65, with the STRUCTURE ANALYSIS reporting 'Specificity anchors present: 3 of 6 (number, length limit, format, audience, examples, criteria)'. The four axes turn a vague feeling into a concrete diagnosis of where a prompt is thin.
Where does the readability report tell me a prompt is vague?
In the OBSERVATION NOTES, which name the specific gap rather than just flagging a number. On this otherwise-clear prompt the notes point out 'No explicit output format was detected', so you know exactly where clarity may suffer. The check is read-only and fixes nothing — it hands you off to the Prompt Cleaner, Rewriter, or Formatter for the actual change.

Fix a Vague Prompt
'Make it good', 'be detailed', 'keep it interesting' — vague prompts get vague output. The fix is mechanical: replace every fuzzy word with a checkable instruction.
