Notion redesigned its text editing system in 2025 to support true collaborative editing by implementing CRDTs (Conflict-free Replicated Data Types), replacing a flawed last-write-wins approach that caused concurrent edits to overwrite each other. The new system ensures conflict-free rich-text editing while also supporting Notion's unique block-based document model, addressing data loss risks especially during offline mode usage.
Background
Notion transitioned from a last-write-wins conflict resolution model to CRDTs in 2025 to support real-time collaborative editing at scale, addressing data loss issues that arose as their user base grew and offline mode was introduced.
