Publish prompts now say your file becomes a private page on claude.ai instead of an "Artifact".
What's wrong with this entry?
Anonymous. No account, no email.
What
The permission prompt for publishing a file no longer describes it as rendering to an "Artifact". It now says the HTML or Markdown file is published as a page on claude.ai, on Anthropic's servers, private by default, and the prompt says whether it goes to a new page or a named existing one.
Evidence
Publish an HTML or Markdown file as a page on claude.ai (Anthropic's servers), private by default.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
