About Meta Tag Diff & Compare

The unified view highlights tags that were added, removed, or changed.
FAQ
What is the difference between "diff" and "compare"?
Both are done by the same tool. "Diff" highlights the lines/parts that changed (added/removed), while "compare" shows how similar the two inputs are (similarity percentage + summary). You get both at once here.
