How to use the Text Compare

Paste an original version and a changed version to compare them line by line. The current Fieldlet highlights lines that were added, removed, or left unchanged.

  1. Paste the original text into the left editor and the changed text into the right editor.
  2. Fieldlet calculates a line-based longest-common-subsequence comparison.
  3. Removed lines and added lines are labeled separately so changes are easier to review.

Common questions

Does this compare individual characters?

The launch version is line based. This keeps long text comparisons readable and fast; word-level highlighting can be added later.
