Prompt Validator

Check a draft prompt before you send it to any language model. Get four dimension scores, evidence, and actionable fixes you can apply in your editor.

Education only

This is a simple rule-based check, not a judgment of your prompt quality in every language or domain.

How it works

  1. Paste your draftUp to 12,000 characters.
  2. Set goal (optional)Nudges a few coding-related checks when relevant.
  3. Review four dimensionsGoal, context, output shape, and constraints, plus a fix list.

Analyze your prompt

What we look for

  • Task verbs & clear ask
  • Audience & background
  • Format & length
  • Tone & boundaries
0 / 12,000characters

Helps weight a few checks (e.g. coding terms when "Coding" is selected).

What this tool does

Prompt Validator helps you tighten instructions so models have less to guess: what you want done, what context matters, how the answer should look, and what is off limits. It is built for learners and practitioners who want practical structure, not a generic “improve this” button with no explanation.

What you get

  • Four dimensions: goal clarity, context completeness, output specification, and constraint quality, each with an ordinal rating.
  • Evidence lines: short notes tied to the rules that fired, so you can see why a dimension was marked strong or needs work.
  • Summary and top fixes: a diagnostic paragraph plus prioritized suggestions for the weakest areas.
  • Checklist: concrete next edits. When you choose a task goal, copy nudges toward coding, writing, research, or creative work.

What this tool does not do

  • It does not replace domain expertise or guarantee model behavior in every language or subject.
  • It does not call a separate AI in the MVP to score your prompt.
  • It is education only, not professional, medical, or legal advice.

Common questions

How does Prompt Validator analyze my prompt?

It applies deterministic rules (for example task verbs, format cues, length, constraints) to score four dimensions and show which rules fired. The MVP does not send your text to a separate AI model for grading.

What does the optional goal setting do?

It tailors checklist items, top fixes, and some guidance toward writing, coding, research, creative work, or a general task so recommendations match how you plan to use the answer.

Is my prompt saved or used to train models?

The MVP does not keep a personal history of utility runs. Avoid pasting secrets you would not share on any website. Details are in Help.

What do Strong, Needs work, and Weak mean?

They are ordinal labels per dimension from the rule engine. They are heuristics to improve drafts, not statistically calibrated scores.

Why was only part of my text analyzed?

Very long inputs may be truncated to a maximum character limit. The tool tells you when truncation applies.
