A link is a snapshot, not sync
Share links encode a compressed copy of a note, sticky board, or mind map into the page URL hash. Anyone who opens the link sees a readable preview, then imports that snapshot as a new local item in their browser.
The public path is /share?title=… so social previews (X, Slack, LinkedIn, etc.) show the 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 content. 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 or boards — especially with embedded images — may need images stripped or a Markdown / PNG / JSON backup instead. The share button guides you through those fallbacks.
Treat share links as portable snapshots. For full fidelity with media, use download or backup export.
