Not available yet. Copy embed snippet is not working in the product today. This page describes what is planned, so do not follow it as steps.
What to do instead: publish the artifact for an audience outside your team, or share the artifact link with teammates. See Share an artifact.
When it lands, Export → Copy embed snippet will give you an iframe that shows the artifact live. Not a screenshot, not a copy: the current version, always.
What it will be for
Anywhere the thing should stay current: an internal wiki, a project page, a status dashboard, a client-facing report.
The embed will be read-only by construction. It shows the artifact, and it cannot be used to edit it.
Visibility will still apply
The planned embed will inherit the artifact's workspace access. A private artifact embedded elsewhere will show a sign-in wall, and only people who can access that workspace will see the content. If the audience is wider, publish the artifact.
Steps
Coming soon. When the snippet is available: open the artifact, select Export → Copy embed snippet, and paste the iframe into your page.
Questions and answers
Why would an embed show a sign-in wall? Because the artifact is in a workspace the viewer cannot access. Viewers without workspace access see the wall rather than the content.
Will the embed update when the artifact changes? Yes. That is the point of it.
Could someone edit through it? No. It is read-only.
What should I use today? Publish for an outside audience, or share the artifact link with your team.
