Early build for Mac

Let your team use AI.
Keep control.

AI makes everyone faster. But someone still has to own the output. Stet is the approval layer. Your team writes with whatever AI they want. Every change goes through review before it ships.

Speed vs. quality is a real trap

AI quietly drops a key detail. A draft reads well but says something you'd never approve. A doc ships before anyone checks what the AI actually changed. The answer isn't "stop using AI." It's a review step that catches it.

What it actually does

An approval layer for AI edits.

Every change, from any source, shows up as a proposal. You review it paragraph by paragraph. Accept, reject, or rewrite. The owner of the doc makes the final call.

A byline for every edit.

You, a teammate, Claude, any agent. Every change is attributed. You can trace any sentence back to its source.

Any AI your team uses.

Claude, ChatGPT, Cursor, a custom script. Stet doesn't ship its own AI or charge for tokens. It just watches the files and surfaces what changed.

Let it stand.

"Stet" is the proofreader's mark for "keep this change." Every AI edit becomes a team decision. The person who owns the doc makes the call. Nothing ships without it.

Try it.

Download Stet, point it at a folder of docs, and let an AI edit something. See what it feels like to approve changes before they land.
