What is Knogra?

Knogra is a knowledge graph explorer for visual learners, researchers, and the deeply curious. It lets you chart a whole subject as one connected graph, broken into focused scenes, with labeled relationships, spatial transitions, and topology-aware AI assistance. It is a desktop-oriented web app that also supports importing and exporting Markdown and Mermaid diagrams.

How to use Knogra?

Open app.knogra.io on your computer and start a new graph. Create your first node, add a neighbour, connect the two, and step into another scene to see the view reorganise. Use the context menu for most commands, follow the step-by-step basics guide, and optionally set up the AI assistant with your own API key (Google Gemini, OpenAI, Anthropic, or OpenRouter) to suggest concepts and connections.
