Knodegraph is a knowledge graph builder that lets you upload documents and automatically extract entities and relationships using AI. You can also build graphs manually with a drag-and-drop editor.

How much does Knodegraph cost?

Knodegraph has a free tier with 3 graphs and 100 nodes per graph. The Pro plan is $14.99/month and includes unlimited graphs, 50,000 nodes, NLP extraction, multilingual support, and API access.

What languages does Knodegraph support?

Knodegraph supports over 100 languages for entity extraction, including English, Arabic (with full RTL support), French, Spanish, German, Chinese, Japanese, and many more.

Is my data secure on Knodegraph?

Yes. Knodegraph uses per-user data isolation, meaning your knowledge graphs are completely separate from other users. All data is stored on secure, self-hosted infrastructure with encrypted connections.

How does AI extraction work?

Upload any document and Knodegraph uses Claude AI to identify entities (people, organizations, locations, concepts) and the relationships between them. Extracted data is staged for your review before being added to your graph - you always have final control.

Can I export my knowledge graphs?

Yes. Free users can export to PNG, SVG, JSON, and CSV. Pro users additionally get access to JSON-LD, RDF, and Neo4j export formats.

Looking for a Roam Research Alternative?

Roam Research pioneered networked thought with bidirectional links and block references. KnodeGraph takes a different approach: instead of linking notes manually, it uses AI to extract typed entities and relationships from documents, building structured knowledge graphs you can visually edit and export.

Why People Look for Roam Research Alternatives

Roam is great for journaling but $15/mo for note-taking feels expensive when I mainly want knowledge graphs.

Roam's pricing reflects its note-taking features. If your primary goal is building knowledge graphs rather than daily journaling, KnodeGraph Pro at $14.99/mo includes AI extraction and graph visualization purpose-built for that use case.

The graph in Roam just shows page connections -- I need to see actual relationships between concepts.

Like Obsidian, Roam's graph shows page-level links. KnodeGraph builds entity-relationship graphs where each connection has a type and direction, revealing the actual structure of knowledge.

I can't upload a research paper and have it automatically mapped out.

Roam requires manual input -- you type everything and create links by hand. KnodeGraph lets you upload documents and automatically extracts entities and relationships using Claude AI.

Block references are powerful but my graph is a mess of thousands of unstructured connections.

Roam's flexibility can lead to graph sprawl. KnodeGraph produces structured graphs with typed entities and labeled relationships, making large graphs navigable and meaningful.

Feature Comparison

Feature	KnodeGraph	Roam Research
Primary use case	Knowledge graph construction	Networked note-taking
Input method	Document upload + AI extraction	Manual typing with [[links]]
Graph structure	Typed entities + labeled relationships	Page links + block references
Graph visualization	Interactive canvas editor	Basic graph overview
Daily workflow	Document analysis and exploration	Daily notes and journaling
AI features	Claude AI entity extraction (100+ languages)	None built-in

Frequently Asked Questions

Is KnodeGraph better than Roam Research?

They solve different problems. Roam is a note-taking tool for capturing and connecting ideas through daily writing. KnodeGraph is a knowledge graph tool for extracting structured entities and relationships from documents. If you write daily notes and build knowledge bottom-up, use Roam. If you analyze documents and need structured graphs, use KnodeGraph.

Can I import my Roam database into KnodeGraph?

You can export your Roam database as Markdown or JSON, then upload those files to KnodeGraph for AI extraction. The AI will identify entities and relationships in your notes and build a structured knowledge graph from them.

Does KnodeGraph have bidirectional links like Roam?

KnodeGraph uses a different model -- typed relationships in a graph database. Instead of note-to-note bidirectional links, you get labeled relationships (e.g., 'Einstein' --[developed]--> 'Theory of Relativity') that carry semantic meaning.

Why is KnodeGraph Pro more expensive than Roam Pro?

KnodeGraph Pro ($14.99/mo) includes AI-powered entity extraction via Claude, a graph database, and visual graph editing. Roam Pro ($15/mo) is a note-taking tool. The price difference reflects the AI compute costs and graph infrastructure included in KnodeGraph.
