Powerful Features
Everything you need to build, explore, and share knowledge graphs.

Upload documents and auto-extract entities and relationships. Powered by Claude AI.
Multilingual
Extract knowledge in any language — English, Arabic, French, and 100+ more. RTL rendering built in.
Export Anywhere
PNG, SVG, JSON, CSV — export your graphs in any format you need for presentations or analysis.
Undo / Redo
Full command history for safe editing. Experiment freely — you can always go back.
Secure & Private
Per-user isolation with encrypted data. Your knowledge graphs are yours alone.
How it works
From raw document to interactive knowledge graph in three steps.
1. Upload a document
Drop in any PDF, DOCX, TXT, or markdown. Multilingual content is supported out of the box — English, Arabic, French, and 100+ more languages work with zero configuration.
2. AI extracts entities and relationships
Claude reads the text and identifies the people, organizations, places, and concepts inside, plus how they connect. Every extraction lands in a staged review before it hits your graph.
3. Explore, edit, and export
Refine the graph with drag-and-drop editing, undo and redo at every step, then export to PNG, SVG, JSON, or CSV. Pro unlocks JSON-LD, RDF, and Neo4j for downstream pipelines.
