Anyone who has watched an AI assistant rewrite a paragraph they spent an hour on knows the specific dread. You asked for a small tweak and got back a stranger’s draft, with no easy way to see what it actually changed. Revise, which launched on 11 August out of Great Barrington, Massachusetts, is built around the opposite instinct. It is a browser-based word processor where every edit the AI makes arrives as a tracked change you can read, accept or reject, one at a time.
That single design choice is the whole point. The AI can draft, rewrite, summarise, translate and research inside the document, but it cannot change a word without showing you first. Every addition and deletion turns up as tracked-changes markup, the same red-and-green corrections Word users have squinted at for twenty years, except here a machine proposes the edits and a human signs off on each one.
Why anyone should care
The stakes are not abstract. An unnoticed AI edit to a figure in a contract, a dosage in a medical document, or a disclaimer in a regulated filing is the sort of mistake that ends in a lawsuit or a fine. That is the real reason most professionals still paste AI output into a separate window and reconcile it by hand: they do not trust a model to touch the live file, because they cannot see what it changed. Revise inverts that. The model works in the document, but the correction, not the finished text, is the deliverable. You review the reasoning and keep the liability where it belongs, with a human.
Revise is aimed squarely at the documents where being wrong is expensive: investor updates, contracts, briefs, proposals, marketing copy. Rather than bolting a chat window onto an existing editor, the company built the AI into the document engine itself, which it argues makes drafting and editing faster than any third-party plugin manages.
- Tracked changes by default: every AI edit is a reviewable correction, compatible with Word’s own tracked changes.
- In-context AI: draft, revise, summarise, translate and research without leaving the page.
- Collaboration: live cursors, view or edit permissions, and a revision history you can travel back through.
- Import and export: Word, PDF, HTML and Markdown.
- MCP support: Revise exposes its editing tools to outside agents, with one-click install through Claude’s Connectors Directory.
The MCP support is the sleeper feature. Because Revise speaks MCP, you can point Claude at a document and have it make edits that still land as tracked changes for you to approve. The accountability layer does not vanish when an external agent does the typing, which is the detail that earns its keep the moment a lawyer or a compliance team is in the room.
The honest limits
This is a version one going up against Microsoft Word and Google Docs, two products with roughly a planet’s worth of muscle memory behind them. Migraine, Inc., the parent company, is a small operation, and moving a whole team off either incumbent is a real ask. Founder Artur Sapek’s line, “AI agents are active collaborators, with humans retaining final control,” is a decent slogan, but slogans do not shift filing habits. There is a free tier, with paid plans from $8 a month, so the cost of a trial is low. Start with a single high-stakes document, the kind where a missed edit costs real money, and see whether the tracked changes save you more time than the switch costs you.
Did you know: Revise’s parent company is legally registered as Migraine, Inc., which is either brutally honest branding for the word-processing trade or a very specific cry for help.
