Prompt Comparison
See exactly what changed between two versions of a prompt before you decide which one to keep.
How it works
Line and word differences
Changed lines are paired so you can see the words that were added or removed, not just that the line is different.
Instructions and structure
Added and removed instruction lines are listed separately, alongside counts for sections, list items, placeholders and “do not” rules.
No performance claims
The tool describes how the text changed. Which version works better has to be measured by running both with the same inputs.
