Documentation Overview

The local-first second brain that Claude remembers.
Karpathy's self-compiling wiki × Zettelkasten — fully local, vault-safe, and MCP-native.

English · 한국어 · 日本語 · 简体中文

🤖 Add to Claude / Cursor · ⬇ Desktop App · ⚡ Quickstart · 🌐 Live Demo

One command to let Claude read your vault:
Terminal
npx -y stellavault setup    # wires the MCP server into Claude Code / Desktop, Cursor, Windsurf, or VS Code
Claude Code user? Install the plugin instead — the MCP server plus /vault-ask, /vault-review, /vault-decision skills, in two commands:
Code
/plugin marketplace add Evanciel/stellavault
/plugin install stellavault@stellavault

A second brain that compiles itself. Stellavault fuses two ideas about how knowledge should live and grow:

🧠 Karpathy's self-compiling wiki — drop in anything (a PDF, a YouTube link, a passing thought) and it's auto-extracted into raw/, then compiled into a clean _wiki/ of concepts and backlinks. Your knowledge re-compiles itself as it grows, instead of rotting in a folder.
🕸️ Zettelkasten — atomic notes, [[wikilinks]], and emergent connections, so a web of ideas (not a folder tree) becomes the real structure of how you think.

The result is one local-first knowledge tool — a full markdown editor, a 3D neural graph, hybrid AI search, and spaced-repetition memory decay — shipped as a desktop app, CLI, Obsidian plugin, and MCP server that lets Claude read your entire vault. No cloud, no API keys, and your original files are never modified.

3D Knowledge Graph
Your vault as a neural network. Local-first, no cloud required.

Highlights

🧠 It compiles itself. Drop in a PDF, a YouTube link, or a half-formed thought — Stellavault extracts it to raw/, then compiles a clean _wiki/ with concepts and backlinks. Knowledge that organizes itself as it grows.
🔍 Search that actually finds it. Hybrid retrieval fuses semantic meaning, exact keywords (BM25), and your own [[wikilinks]] / #tags with weighted RRF, then re-ranks by an FSRS memory model so what you're actually using resurfaces. 50+ languages, fully local, zero API keys.
🌌 Your mind, in 3D. A real-time neural graph (React Three Fiber) — cluster view with folder drilldown, per-note local graphs, tag overlays, and two-class edges that keep your wikilinks visually distinct from AI-inferred similarity. Scales to a full 17k-note vault. A way to see the shape of what you know.
🤖 Claude reads your entire vault. A first-class MCP server (21 tools): Claude can search, ask, draft, lint, and analyze your knowledge from Claude Code, Claude Desktop, Cursor, Windsurf, or VS Code.
⏳ It never silently forgets. FSRS memory decay surfaces the real notes you're about to lose — plus gap, contradiction, and duplicate detection across the whole vault.
🔒 Local-first. Vault-safe. Zero keys. Local embeddings, an on-device vector store, and your original files are never modified. Nothing leaves your machine unless you opt in.

Why Stellavault?

Most tools make you choose between writing, searching, and remembering. Stellavault does all three — locally, and in a way Claude can read.
