A link is a snapshot, not sync
Share links encode a compressed copy of the note (title, content, tags) into the page URL hash. Anyone who opens the link imports that snapshot as a new local note in their browser.
The public path is /share?title=… so social previews (X, Slack, LinkedIn, etc.) show the note title and a short description — crawlers never see URL hashes, so the title has to live in the query string.
There is no Browser Notes server storing the shared note. The link is the package. That keeps the local-first story intact: you publish a copy when you choose to.
Built-in limits (on purpose)
URLs have size limits. Large notes — especially with embedded images — may need images stripped or a Markdown download instead. The share button guides you through those fallbacks.
Treat share links as portable text snapshots. For full fidelity with media, use download or backup export.
