About
A personal knowledge management system that combines Claude AI with Obsidian to create an automated second brain that ingests, processes, and connects all your notes, articles, and ideas without manual maintenance.
What it can do
Automatically ingest and process notes from various sources
Notes, articles, documents from multiple formats and sources → Structured, searchable content in Obsidian vault
Generate connections between related ideas and concepts
Existing notes and new content in knowledge base → Automatically created links and relationship mappings
Extract key insights and summaries from lengthy content
Long articles, documents, or research papers → Concise summaries and highlighted key points
Answer questions using your personal knowledge base
Natural language questions about stored content → Contextual answers drawn from your notes and articles
Organize content into thematic clusters and tags
Raw notes and unstructured information → Categorized content with relevant tags and folder structure
Generate new ideas by connecting disparate concepts
Existing knowledge base and creative prompts → Novel insights and creative connections between ideas
Why it made the leaderboard
A concrete setup wiring Claude into Obsidian so your notes get ingested, connected, and made queryable instead of rotting in folders. Steal the architecture if you have bounced off every "second brain" that was all capture and no retrieval.
