- Read the score and the three weakest dimensions it flags.
- Apply the suggested edits and re-run until the score stops moving.
Frequently asked questions
What does the score measure?
Clarity of the task, the context you supplied, the constraints on format and length, and whether the prompt tells the model what a good answer looks like.
Does it work for Claude and Gemini as well as ChatGPT?
Yes. The dimensions it scores are model-agnostic; a prompt that scores well here behaves well in any current model.
Is my prompt stored anywhere?
No. Scoring runs in your browser and nothing is sent to a server.
