Rewrite diff viewer

Rewriting tools are instructed to make text sound human, and they do that by removing hedges, shortening sentences and swapping vocabulary. They also, occasionally, delete a qualifier that made a claim true, or turn a hedged estimate into a flat number. Read the new version on its own and it looks better. Read the two together and you can see the sentence that lost its "up to".

The same view catches the opposite failure: a rewrite that changes nothing. If the diff is a wall of substitutions with no structural change, the text has been reworded rather than improved, and the reader will still feel the original shape underneath it.

First, claims. Every deletion of a number, a date, a qualifier or a source is a decision — confirm you meant to make it. Second, meaning. Words like may, most and typically carry weight, and a rewrite that drops them has made a stronger claim than the original. Third, voice. If the rewrite introduced phrasing you would not use in conversation, it has replaced one costume with another.

For client work, the comparison is the deliverable's audit trail: it shows what was edited and lets a reviewer accept or reject each change. Keep both versions alongside the final text rather than overwriting the original, and the edit history stays available the next time someone asks what changed.
