Stet editor showing a product spec with inline change marks and a sidebar listing edits from Claude and human collaborators

Most tools treat AI like a human

The words just appear. No attribution. No review step. A week later you can't tell what you wrote and what the model filled in. The doc carries your name either way.

What it actually does

Accept, reject, refine.

Edits show up as cards in a review sidebar. One per paragraph. Accept the good ones. Reject the bad ones. Tweak the ones that are close. Nothing lands without your call.

A byline for every edit.

You, a teammate, Claude, any agent. Every change is attributed. You can trace any sentence back to its author, today or a year from now.

Plain files. Any agent.

Your docs are markdown on your machine. No proprietary format. Any AI that can read a file becomes a collaborator. No integration, no API key.

Let it stand.

"Stet" is the proofreader's mark for "keep this change." Every AI edit in Stet becomes that decision. You decide what stays. That's the whole product.

Try it.

Download Stet, point it at a folder of markdown, and let an AI agent edit a doc. See who wrote what. Review every change before it lands.
