Grok.me management

A local index of your published apps. Checking a host only reads the public page. Rename, access, covers, and unpublish still happen in that app’s Build chat, on Publish.

Official controls

Open the Build conversation for that app. Publish sits on the preview bar. This board cannot change the live site.

Address
The Publish sheet mints the grok.me name. Change it there, then publish again.
Access
Just you, anyone with the link, or the whole internet.
Cover
Regenerate, upload, or ask that same chat to redesign the share card.
Update
Edits in the chat stay in preview until you publish again.
Also there
Custom domain, remix, GitHub export, secrets, and per-app model access.
