Spotting what changed between two versions of a contract, a config file, or a draft is slow and unreliable by eye. This diff checker aligns the two texts line by line and colours additions, deletions, and matches, so the actual change stands out immediately.
Line by line, using a longest-common-subsequence alignment. That is the standard approach for documents and code and keeps the output readable.
Because a line is the unit of comparison. A single altered word marks its line as removed and re-added, which is how version control diffs behave too.
Yes. Indentation and blank lines are preserved exactly, so source files, YAML, and JSON all compare cleanly.
No. The comparison runs entirely in your browser, so you can safely diff private or unreleased material.
