Text Diff Checker FAQ
What do the diff colors mean?
Added lines, removed lines, and modified lines use separate colors so changes are easier to scan.
Is this a full code diff tool?
It is a simple line-by-line text comparer for quick checks. Larger code reviews should use Git or a dedicated diff viewer.
Can I copy a summary?
Yes. Copy Summary creates a plain-text view of changed lines.
