Review, compare and redline Word documents inside Claude and ChatGPT.

Your AI proposes the changes. Scaffold turns each one into a real Word tracked change with its reason, and keeps track of where you are in the document, so you don't have to.

Scaffold reviewing a contract's tracked changes one at a time

Works inside Claude ChatGPT through the Scaffold MCP connector. No add-in, no desktop install.

What it does

Contract review output your team can actually use.

Claude and ChatGPT can analyze a contract, but they don't turn each recommendation into a Word file you can review. Scaffold does: tracked changes, version history and comparison, in the browser or inside your AI.

Review

Every proposed change, one at a time.

Each edit your AI proposes carries its plain-English reason. Approve or reject it, and the Track moves you on to the next one. You always see how many are left. Page thumbnails mark where the changes are, so one click takes you to any page.

Scaffold's review screen: a Master Services Agreement with change 1 of 3 open, its reason, Reject and Approve buttons, and page thumbnails down the left, the first marked with 3 changes

Compare

Compare two versions, word by word.

Pick any two versions and Scaffold shows what changed, down to the word. Add a change to the earlier version, or revert it in the later one.

Comparing version 3 with version 8: one changed sentence with the old wording struck and the new wording inserted

History

Every version, and what went in.

Each version keeps its own Track: green for what went in, red for what was turned back. Tick two versions to compare them.

Version history: eight versions, each with a Track showing how many changes went in and how many were turned back
