Build a personal knowledge graph, privately

PixelOkay Knowledge Graph Builder is a free visual workspace for brainstorming, organizing notes, mapping research, linking people and topics, and explaining how ideas relate. Add labeled connections, search and filter notes, focus on neighboring ideas, and arrange your graph using grid, circle, or relationship-based layouts.

How do I connect notes?

Create two nodes, choose Connect, then select the source and target node. Give the relationship a label, such as “supports,” “depends on,” or “inspired by.” Every node can hold private notes and tags.

How do I save or share a knowledge map?

Choose Save map for an editable .json file, and Open to continue later. Export as SVG or PNG for presentations, or CSV files for structured data. Local browser recovery is an optional safety copy—not a substitute for saving.

Does this require an account?

No. Nodes, notes, and relationships are processed locally in your browser. External services are not required for the editor. Keep downloadable project files for reliable storage across devices and browsers.

EXPORT

Take your ideas anywhere

Choose an export format. Your map stays on this device.
LOCAL SAFETY COPIES

Recovery center

Review saved browser copies. Restoring replaces the current map; downloading a copy does not.

Knowledge Graph guide

Add: Click “Add knowledge node,” or double-click blank canvas. Edit the title, notes, category, and tags in the inspector.

Connect: Click “Connect,” then choose the two nodes. Relationships can be directed or undirected, and have editable labels.

Navigate: Drag nodes to move them, drag empty canvas to pan, scroll to zoom. Use the left list for keyboard-friendly selection.

Ctrl/⌘ + S Save map · Ctrl/⌘ + Z Undo · Ctrl/⌘ + Shift + Z Redo · / Search

N Add node · C Connect · Esc Cancel connection / clear focus · Delete Remove selected · ↑ ↓ ← → Move selected node (outside form fields).

Path finder: Choose two nodes in the explorer to trace the shortest connection route. Check “Respect arrow directions” to follow directed links only. Use the tag filter to explore shared themes. Reverse an existing relationship in the relationship inspector. Recovery: Review, restore or download local backup copies. Privacy: The editor makes no upload requests. A local browser backup may help recovery, but storage can be cleared at any time. Download your JSON map regularly.

Using Knowledge Graph Builder

Add notes, connect related ideas and label the relationships. Use categories or tags to focus the map, explore a path between nodes and keep an editable JSON backup alongside shared diagrams.

This is a manually authored knowledge map, not automatic document extraction or AI research. Markdown is an outline export rather than an import format. Node, relationship and recovery budgets are bounded; local recovery is not durable storage or cloud synchronization.

Choose an editable knowledge map or a sharing format

Practice: connect three research notes

  1. Create fictional notes named Question, Evidence and Next check.
  2. Connect them with clear relationship labels and add a tag for the topic.
  3. Explore a path between notes and inspect which links it follows. Save JSON before exporting a diagram or outline.

This is an authored note-mapping exercise, not researched evidence or an automatically extracted knowledge graph.

Knowledge graph questions

Does the graph verify a claim or extract facts with AI?

No. Notes and relationships are authored manually. A shortest graph path describes the links you entered, not verified truth or a research conclusion.

Can I restore my editable map from a Markdown outline?

Markdown is an export, not an import format here. Keep the project JSON for reopening; browser recovery is bounded and does not create a cloud-synchronized backup.
