What Is Text Compare?
Two near-identical documents arrive and you need to find every difference. Reading both windows side-by-side is exhausting and you'll miss small swaps.
Paste both versions and see additions and removals highlighted instantly.
If you're reviewing contracts, you flag every changed clause. If you're auditing configs, you spot drift from gold-standard templates. If you're checking drafts, you find transposed numbers and swapped words fast.
Frequently Asked Questions
What algorithm matches lines?
Line-by-line LCS (longest common subsequence) matches identical lines and flags the rest.
Tip: Best when paragraph structure is similar.
Can I diff JSON or YAML?
Yes, line-level works on code. Semantic diff needs specialized tools.
Tip: Pretty-print JSON first for cleaner structural diffs.
vs Difference Checker?
Compare shows side-by-side. Difference Checker lists phrases as a change-log.
Tip: Compare for visuals, Checker for change logs.
Can I ignore whitespace?
Yes, toggle to treat indentation as equivalent.
Tip: Ignore for prose, never for Python source.
Document size limits?
Tens of thousands of lines per side. Multi-MB files lag.
Tip: Use git diff for huge files.
How do I share the diff?
Copy the output as text or screenshot the panel.
