How it works

Three steps to better AI output

01

Paste your prompt

Drop in any prompt you use with ChatGPT, Claude, Gemini, or any AI tool. Works with system prompts, user prompts, and templates.

02

Get your audit

PromptCheck scores across clarity, token efficiency, and specificity in seconds. See exactly what's weak, what it's costing you, and why.

03

Use the rewrite

Every audit includes an AI-rewritten version scoring 80+. Copy it and immediately get better results — on the first try.


What we measure

Every dimension of prompt quality

Clarity Score

Measures how unambiguous your intent is. Vague pronouns, missing context, and undefined references all tank your score — and your results.

Token Efficiency

Identifies redundant words, filler phrases, and repeated instructions that waste tokens and inflate your API bill at scale.

Specificity Analysis

Flags missing parameters: no length limit, no format instruction, no audience definition. The more specific your prompt, the better the output.

Instant Rewrite

Every audit includes a fully rewritten prompt that scores 80+ across all dimensions. One click to copy. Immediate improvement.
