Knowledge Engine
Every link you save becomes part of a living knowledge system — entities are extracted, notes are cross-referenced, and synthesis pages emerge automatically.
Auto-generated topic pages that aggregate knowledge across notes. AI synthesizes insights from all content about a subject.
Notes are automatically linked by semantic similarity. Discover connections you didn't know existed across your vault.
Browse all extracted entities by type. Click any person, concept, or tool to see every note that mentions it.
Track everything — notes processed, relations discovered, synthesis pages created, entities extracted. Full transparency into your knowledge growth.
Every Sunday, AI generates a weekly knowledge synthesis — summarizing themes, highlighting connections, and suggesting explorations.
Tell AI how to process your content. Prioritize certain topics, customize categorization, or focus on specific entity types.
