Frequently Asked Questions
- How does it compare text?
- It runs a line-by-line longest-common-subsequence (LCS) diff — the same approach used by version-control tools — to find added, removed, and unchanged lines.
- Does it compare word-by-word?
- It compares whole lines. A changed line appears as one removed line plus one added line.
- Is my text sent anywhere?
- No. The comparison runs entirely in your browser.
