AI Prompt Scoring
Understand prompt quality with a clear scoring framework.
The Prompt Lab is a prompt scoring tool that turns prompt quality into explainable metrics so you can see why a prompt is strong or where it still needs work.
Score structure
Format + sequencing
Measure how well the prompt guides output format, sequencing, and section ordering.
Score reliability
Constraints + audience
Check whether the prompt defines who it is for, what limits apply, and how the result should be used.
