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.

KnodeGraph vs Notion AI (2026)

Verdict

Choose Notion AI if you want one workspace for docs, wikis, databases, and projects with an AI assistant that writes, summarizes, and answers questions across all of it. Choose KnodeGraph if you need structured knowledge — typed entities and relationships extracted from documents into a visual, queryable graph. Notion has no graph view; KnodeGraph is no workspace.

An Assistant Over Prose vs a Graph From Documents

Notion AI is an assistant layered over the Notion workspace. It drafts and rewrites text, summarizes pages, autofills database properties, and answers questions across your workspace and connected tools like Slack and Google Drive. Its output is prose and database fields inside Notion pages.

KnodeGraph does one thing Notion does not attempt: it converts documents into a structured knowledge graph. Upload PDFs, text, or Markdown, and Claude AI extracts typed entities and the relationships between them, staged for your review before they join an interactive graph you can explore, filter, and edit.

The distinction matters because prose and graphs answer different questions. Notion AI can summarize what a document says; KnodeGraph can show you every organization mentioned across fifty documents and exactly how they connect. One produces text you read; the other produces structured data you can filter, traverse, and export.

Where Notion AI Wins

If your team already runs on Notion, the AI add-on is the path of least resistance: zero new tools, zero migration, and the assistant inherits your existing wikis, meeting notes, and project databases as context. Its Q&A can search across the workspace and connected apps, which no standalone knowledge-graph tool can do out of the box.

Notion is also simply a more complete collaboration product. Real-time co-editing, comments, granular permissions, databases, boards, and a huge template ecosystem make it a genuine all-in-one replacement for several point tools. KnodeGraph offers none of that — it is a focused analysis tool, not a place where your team writes and plans.

For everyday writing assistance — drafting, rewriting, translating, summarizing meeting notes — Notion AI is the better daily driver.

Where KnodeGraph Wins

Notion has no graph view and no concept of typed entities. If you ask 'which people appear in these documents and which organizations employ them?', Notion AI can write you a paragraph; KnodeGraph gives you an actual graph you can traverse, filter by entity type, and export as JSON or CSV for downstream analysis.

KnodeGraph's extraction is also reviewable: every AI-proposed entity and relationship sits in a staging area where you approve, edit, merge, or reject it. That human-in-the-loop step is what makes the resulting graph trustworthy enough to cite — there is no equivalent verification workflow for Notion AI's generated answers.

Extraction works in 100+ languages including Arabic with RTL support, and the Pro plan exposes a REST API so the graph data can feed other systems.

Pricing Compared

Notion's free plan includes only limited AI responses. To use Notion AI properly, a paid seat is required: Notion Plus at $10 per user per month plus the AI add-on at $10 per user per month — $20/user/mo in total, scaling with team size.

KnodeGraph is flat-priced: $0 for the free tier (3 graphs, 100 nodes per graph, 5 AI extractions per month) and $14.99/mo for Pro (unlimited graphs, 50,000 nodes, 50 extractions per month, templates, API). For an individual researcher, KnodeGraph Pro costs less than a single Notion-plus-AI seat.

Which Should You Choose?

Choose Notion AI if you need a workspace first and an assistant second — your team's docs, wikis, and projects in one place, with AI that drafts and answers questions over them.

Choose KnodeGraph if you need structure: a typed, visual, exportable knowledge graph extracted from source documents, with a review step that keeps it accurate. Researchers, analysts, and journalists mapping entities across large document sets fall squarely on this side of the line.

They pair naturally. Export any Notion page to Markdown and upload it to KnodeGraph for extraction, or embed a link to your KnodeGraph project inside the Notion page where the team documents its research. Notion remains the workspace; KnodeGraph becomes the structural layer underneath it.

Frequently Asked Questions

Does Notion have a knowledge graph or graph view?

No. Notion organizes content as pages and databases. There is no graph visualization and no typed entity-relationship model. KnodeGraph exists precisely to provide that structure.

Can Notion AI extract entities and relationships from documents?

Not as structured data. Notion AI can summarize a document or autofill database properties, but it does not produce a typed entity-relationship graph you can visualize, query, or export. KnodeGraph's extraction pipeline is built for exactly that.

Is KnodeGraph a Notion replacement?

No. KnodeGraph has no wikis, databases, project boards, or collaborative editing. It replaces the manual work of building a knowledge graph from documents — not your team workspace.

Which is cheaper for a single user?

KnodeGraph. Pro is $14.99/mo flat, while Notion Plus with the AI add-on is $20/user/mo. Both products offer free tiers: KnodeGraph with 3 graphs and 100 nodes, Notion with limited AI responses.

Can I use Notion and KnodeGraph together?

Yes. Export Notion pages to Markdown and upload them to KnodeGraph for entity extraction, then link the resulting graph from your Notion workspace. Notion handles the writing; KnodeGraph handles the structure.
