Update shared artifacts with edit access

Let someone edit with you

People you share with are viewers by default: they see each version you publish but can't change the page. On Team and Enterprise plans, you can also make someone an editor. In the share dialog, add a person and switch their role from viewer to editor.

An editor publishes new versions the same way you update the artifact from another session: they give Claude the artifact's URL, or attach it from /artifacts, and Claude pulls the current content and republishes with their changes. Everyone with the page open sees each update live.
