Cross Device Sync And Offline Reading Support

via “cross-device-highlight-sync”

Social web highlighter with AI summarization.

Unique: Implements differential sync with offline queueing, allowing highlights created offline to be persisted locally and synced to the cloud when connectivity is restored. Uses last-write-wins conflict resolution to avoid complex merge logic.

vs others: More seamless than manual export/import workflows because sync is automatic and bidirectional, but less sophisticated than operational transformation (OT) or CRDT-based systems because it doesn't handle simultaneous edits from multiple devices without conflicts.
