The Stack

Two layers. One graph.

Use the engine headlessly from your agents, or run the desktop app for the polished daily-driver experience.

⚡

wikiX Engine

The open-core temporal knowledge engine. Self-host on a single port with Docker. Drive it from Claude Code, Cursor, or any MCP client.

Single-port Caddy ingress
13-tool MCP server surface
Bi-temporal graph with Neo4j
Hybrid retrieval: pgvector + graph
AST-first code extraction

◈

wikiX Desktop

The native daily-driver. Cytoscape graph viewer, syntax-highlighted book reader, streaming chat with tool cards, and an MCP Gateway.

Native graph visualization
Mermaid + KaTeX rendering
SSE chat with tool-call cards
Smart corpus folder watcher
Insights dashboard + spend telemetry

Agent Integration

One config. All IDEs.

Point Claude Code, Cursor, Codex, or Aider at the MCP server and start querying your knowledge graph immediately.

Capabilities

Built for agents.
Designed for humans.

Bi-Temporal Correctness

Every fact carries a validity window. Query the graph "as of last Tuesday" and get the world exactly as it was. Contradictions invalidate old edges—they don't erase them.

AST-First Extraction

Tree-sitter parsers for Python, TypeScript, Go, Rust, Java, and C/C++ produce deterministic code graphs. Every symbol has a precise source span and line range.

Confidence Taxonomy

EXTRACTED beats INFERRED beats AMBIGUOUS. A hallucinated edge cannot silently overwrite tree-sitter ground truth. It becomes a reviewable ConflictEvent instead.

Two-Pool Retrieval

Chunks live in pgvector + tsvector. Entities and edges live in the temporal graph. Each pool gets its own cross-encoder rerank. Returned side-by-side, never blindly fused.

Wiki Book Distillation

Every wiki auto-distills into chapters bucketed by Leiden community detection. A cite_check lint pass pills uncited paragraphs as *[cite needed]*.

Incremental AST Diff

Re-running over an unchanged file is free. When a file edits, we walk the AST diff, emit a delta episode, and surgically re-embed only what changed.

Desktop App

The graph,
in native form.

wikiX Desktop wraps the entire engine in a polished native interface. Visualize your knowledge graph with Cytoscape.js, read auto-generated wiki books with syntax highlighting, and chat with your corpus through a streaming SSE interface.

✓ Cytoscape graph viewer with fcose + dagre layouts
✓ Shiki-highlighted code blocks + Mermaid diagrams
✓ MCP Gateway with per-IDE token grants
✓ Insights tab: god-nodes, surprising connections, Atlas
✓ Signed .dmg / .msi / .AppImage releases
