Paste any ChatGPT, Claude, or Gemini prompt and get an instant 0–100 score with specific fixes — so you stop getting generic answers. Free, private, no sign-up.
Drop any prompt above and get an instant score with specific fixes.
Add a role, e.g. “Act as a senior copywriter…” so the model adopts the right expertise and tone.
Spell out the situation, who it’s for, and the goal. Most generic answers come from missing context.
State exactly what you want done with a strong verb and a specific deliverable (e.g. “write a 5-email sequence”).
Add constraints: length, tone, what to avoid, must-include points. Constraints turn an almost-right answer into the right one.
Tell it how to format the answer (table, numbered steps, JSON…) so it’s usable immediately.
Too short — add the specifics (names, numbers, examples) the model needs.
Add fill-in-the-blank placeholders like [PRODUCT] or {audience} to turn it into a reusable template.

Every great prompt shares the same seven traits. The grader scores each one — here's what they mean and why they matter.
Tell the model who to be — 'act as a senior CFO'.
The situation, who it's for, and the goal.
A specific deliverable with a strong verb.
Length, tone, must-include, what to avoid.
Table, numbered steps, JSON — how to format.
Concrete names, numbers, and examples.
Placeholders like [PRODUCT] so you can reuse it.
It scores your prompt 0–100 across the seven traits of an effective prompt: a clear role, context and audience, a specific task, constraints, an output format, specificity/length, and reusable placeholders. Each gets a pass, partial, or fail with a specific fix. The scoring is rule-based and runs entirely in your browser — instant and private.
Yes, completely free with no sign-up. Paste any ChatGPT, Claude, or Gemini prompt and get an instant score and fixes. If you want the prompt rewritten for you automatically, the Pro AI Improver does that.
A strong prompt assigns a role ('act as a…'), gives context and audience, states a specific task, sets constraints (length, tone, what to avoid), specifies an output format (table, list, JSON), includes concrete specifics, and uses placeholders so it's reusable. Hit those and you rarely need a 'magic' prompt.
No. The grading happens locally in your browser — your prompt is never uploaded or stored. You can grade sensitive or proprietary prompts safely.
Usually because it's missing a role, context, constraints, or an output format — the things that stop a model from defaulting to generic answers. Check the failing items in the breakdown and add what's missing, or use the AI Improver to rewrite it.
