Insights Example

💡 Vault Insights (all | all priority)

Found 3 actionable insights:

**23 Orphaned Notes Found** (medium)
9% of your notes (23 out of 247) have no incoming links, making them difficult to discover.
Action: Review orphaned notes and create connections to related content. Start with recent notes or those with valuable information.

**Knowledge Hub Notes Identified** (low)
You have 12 notes that serve as knowledge hubs with many connections. These are valuable reference points.
Action: Maintain and expand these hub notes. Consider adding overviews, summaries, or organizing them as MOCs (Maps of Content).

**Strong Note Connectivity** (low)
Your notes average 4.7 backlinks each, indicating good interconnectedness.
Action: Continue building connections between ideas. Consider creating overview notes that link to clusters of related content.
