Nexus Prime vs Cursor Memory
Cursor has built-in memory — but it's cloud-synced, limited to Cursor, and doesn't persist architecture decisions. Here's the full comparison.
The key difference: local vs cloud, one agent vs all
Cursor’s built-in memory is convenient — but it syncs to Cursor’s cloud, only works in Cursor, and is limited to conversation history. Nexus is local-first, works across 12+ agents, and stores structured architectural knowledge.
