Preview before publishing
Use Share, inspect the transcript, set the title if needed and confirm publication. New shares default to public, indexable and listed at /shared/. Uncheck Allow search engines to index this page to create an unlisted public snapshot marked noindex,follow, excluded from the sitemap. This is not private access control. For indexable snapshots the publication notice also states that eligible user text contributes to shared recall and neural training. Revoking that snapshot removes its contribution and resets shared weights for retraining; separately opted-in chat contributions remain until withdrawn. Existing snapshots keep their indexing choice; publish a new snapshot for a different choice.
What the shared URL contains
The saved HTML includes the transcript, content-based description, self-canonical URL, Open Graph metadata and structured data. It can be read without JavaScript. The /shared/ directory uses 50-item pages, with crawlable numbered links to /shared/page/2/ and subsequent pages. Every directory page has its own canonical URL. Directory links and the share sitemap help crawlers discover indexable snapshots.
Links and duplicate content
Public indexable pages use index,follow. Transcript URLs carry ugc nofollow noopener noreferrer by default. Directory, navigation and pagination links remain ordinary followed links. Previously link-only snapshots keep noindex,follow. Two identical transcripts are still duplicate content even if their titles differ; metadata cannot guarantee indexing or rankings.
Remove access
Revoke a snapshot in Share to remove it from the service and discovery lists. Saved copies, search caches and third-party archives may remain. A share is an immutable snapshot; editing the live conversation does not rewrite it.
If a share opens the homepage
The /share/ path must reach the backend. The installer checks a real snapshot through local HTTPS Nginx and rejects homepage fallback. Each valid share must canonicalize to its own URL, not to the homepage.
