You are a knowledge management systems architect with expertise in local-first software design. Create a comprehensive plan for a Markdown-based knowledge base desktop application with AI-enhanced retrieval.

Core Requirements

1. Local-First Architecture

  • All data stored as plain Markdown files on the local filesystem
  • No cloud dependency for core functionality
  • Git-compatible for version control and sync
  • Support for YAML frontmatter metadata

2. AI-Enhanced Features

Smart Search & Retrieval:

  • Hybrid search: full-text + semantic vector search over local files
  • Natural language queries ("What did I write about X last month?")
  • Local embedding model (e.g., all-MiniLM-L6-v2) for privacy
  • Incremental index updates on file change detection

Auto-Tagging & Classification:

  • Automatically suggest tags based on content analysis
  • Detect duplicate/similar notes and suggest merging
  • Topic clustering for organizing unstructured notes
  • Confidence scores for each suggestion

Bidirectional Link Recommendations:

  • Analyze note content to suggest relevant connections
  • Surface "orphan" notes that lack connections
  • Generate relationship strength scores
  • Visualize as interactive knowledge graph

AI Writing Assistant:

  • Context-aware autocomplete using surrounding notes
  • Summarize long notes into key points
  • Expand bullet points into full paragraphs
  • Generate questions for review/spaced repetition

3. Technical Stack Recommendations

  • Desktop framework (Electron/Tauri/native)
  • Local vector database (SQLite-vec, LanceDB, or Chroma)
  • File watcher for real-time index updates
  • Plugin architecture for extensibility

4. Performance Targets

  • Index 10,000+ notes in <30 seconds initial build
  • Incremental updates in <100ms per file change
  • Search results in <200ms
  • App startup in <2 seconds

Deliverables

  1. System architecture with component diagram
  2. Data model (file format + index schema)
  3. AI pipeline design (embedding, retrieval, generation)
  4. UI/UX wireframes description for key screens
  5. Technology selection matrix with trade-offs
  6. Development roadmap (MVP → V1 → V2)
  7. Privacy & security considerations
