You have a 200-page PDF. Inside it: entities, relationships, hierarchies, processes, dependencies — a web of knowledge buried in linear text. Reading through it takes hours. Understanding the connections between concepts? Even longer.
What if you could upload that PDF and get an interactive knowledge graph in seconds? Not a generic summary — a grounded visual map of the actual entities and relationships extracted from your document.
That's what Citra AI's diagram generator does.
The Problem: Documents Are Linear, Knowledge Isn't
PDFs, reports, and research papers present information sequentially — page after page. But the knowledge inside them is networked. Concepts connect across sections, chapters reference each other, dependencies span multiple documents.
Traditional approaches to extracting this structure:
- Manual diagramming — Read everything, then manually draw relationships in Lucidchart or Miro. Hours of work for a single document.
- AI summaries — Tools like ChatGPT can summarize content, but the output is still text — not visual.
- Basic visualization tools — NotebookLM offers mindmaps and diagrams, but doesn't generate knowledge graphs — the deepest form of relationship extraction. Other mind-mapping tools produce shallow hierarchies without real entity-relationship understanding.
None of these produce a grounded visualization, connected to your actual documents, that updates when your knowledge evolves.
What Citra AI Generates
When you upload documents to Citra Vault and request a diagram, the AI extracts entities, relationships, hierarchies, and processes directly from your documents. Here are the diagram types available:
Knowledge Graph
Entities as nodes, relationships as edges. See how concepts connect across your documents.
Mindmap
Hierarchical breakdown of themes and sub-topics. Great for research papers and reports.
Flowchart
Process flows and decision trees extracted from procedural documents.
Process Diagram
Step-by-step workflows with dependencies. Ideal for operational docs and SOPs.
Step-by-Step: PDF to Knowledge Graph
Upload PDFs to Citra Vault
Create a Vault and upload your documents — research papers, reports, SOPs, technical specs. The AI indexes the full content, extracting entities, terminology, and structure.
Select your diagram type
Choose Knowledge Graph for relationship mapping, Mindmap for hierarchical breakdowns, or Flowchart for process visualization. You can also let the AI suggest the best format.
Generate the visualization
Citra AI reads your Vault context, extracts the relevant entities and relationships, and renders an interactive diagram. Every node and edge traces back to a source in your documents.
Add to a presentation or report
Drop the diagram into a slide deck or executive summary. It becomes part of your living presentation — connected to the same Vault.
Update when documents change
Add new PDFs or replace outdated ones in the Vault. Regenerate the diagram. The visualization reflects the latest state of your knowledge base.
Real-World Use Cases
Literature Reviews
Upload 20+ research papers. Generate a knowledge graph showing how studies reference each other, which methodologies are shared, and where findings conflict.
Regulatory Compliance
Upload policy documents and regulations. Visualize which requirements map to which internal procedures, and identify gaps.
Technical Documentation
Upload architecture docs, API specs, and design documents. Generate a dependency graph showing how systems connect.
Due Diligence
Upload financial reports, contracts, and market research. Map entity relationships, ownership structures, and risk dependencies.
Why Grounded Diagrams Matter
Generic AI tools can generate diagrams from prompts — but they're not grounded in your actual documents. They hallucinate nodes, invent relationships, and produce diagrams that look impressive but aren't accurate. Citra AI's diagrams are extracted from your uploaded documents, with every connection traceable to a source. This is the difference between a diagram that looks right and one that is right.
From Diagram to Presentation in Seconds
The real power is the connection between diagrams and presentations. In Citra AI:
- Generate a knowledge graph from your PDFs.
- Add it to a presentation slide with one click.
- Generate additional slides from the same Vault — text, charts, summaries — all grounded in the same sources.
- Share the presentation. When your PDFs are updated, refresh both the diagram and the slides.
No tool-hopping. No exporting SVGs from one app and importing into another. No manually redrawing when documents change. The diagram, the presentation, and the knowledge source are all part of one connected workspace.
