Vaultmind
RAG-optimized personal knowledge management system built with Tauri + Rust + Svelte
VaultMind
RAG-optimized personal knowledge management system.
VaultMind is a desktop app built with Tauri 2.0 where Retrieval-Augmented Generation (RAG) is a first-class architectural concern — not a plugin afterthought. Every note you create is automatically parsed, chunked, embedded, and connected in a knowledge graph for high-quality AI-powered retrieval.
Why VaultMind?
| Obsidian + Plugins | VaultMind | |
|---|---|---|
| Chunking | Naive (per-file/heading) | AST-based with hierarchical context |
| Embeddings | Plugin dependency | Built-in (ONNX, local-first) |
| Knowledge Graph | Link graph only | Explicit (wikilinks) + implicit (semantic similarity) |
| AI Agent | Chat-only | Action-capable (create, edit, link, refactor notes) |
| Retrieval | Vector search only | Hybrid (vector + BM25 + graph expansion + re-ranking) |
| Architecture | Plugin bolt-on | RAG as core design principle |
Features (Roadmap)
- Phase 1 — Markdown editor with wikilinks, tags, full-text search
- Phase 2 — Smart chunking pipeline with local embeddings (ONNX)
- Phase 3 — Knowledge graph + hybrid retrieval + Q&A
- Phase 4 — AI agent with action capabilities
- Phase 5 — Multi-modal (PDF, images, audio) + plugin system
Tech Stack
| Layer | Technology |

| Full-Text | Tantivy |
| Embeddings | ONNX Runtime (all-MiniLM-L6-v2) |
| Graph | petgraph |
