Red rows were removed, green rows were added, and adjacent remove/add pairs highlight the exact token-level edits.
Why this one is useful
It is faster than manual scanning when two notes, prompts, changelogs, or copied outputs are almost the same.
Whitespace, case, and blank-line toggles help separate meaningful edits from noisy formatting changes.
Inline token highlights make same-line edits much easier to spot when the wording only changed slightly.
Common uses
Comparing policy drafts, prompt revisions, and release notes.
Checking whether copied API responses changed between runs.
Reviewing edits to config snippets, markdown files, and plain-text exports.
