A local revision instrument

Turn of Phrase

Put two versions of a passage beside each other. This small tool traces the actual token-level spine they share, then lets you touch the turns where the prose changes. It keeps a record, not a score.

The local trace is ready. Pick any thread to inspect the exact words.

Each quiet word survives in the longest shared sequence. Coloured threads are contiguous passages that were removed, added, or turned into something else. Select one to see the precise before-and-after pair.

What changed, without pretending to judge it

The breathing of the two versions

Before

After

Your text stays in this browser tab unless you deliberately download a local record. The trace uses word and punctuation alignment; it cannot know why a change was made, whether it improved the writing, or what an author intended.
