+## From graph to AI
+
+### Data Persistence
+
+ArangoDB is a scalable database system that you can use to store
+[JSON documents](arangodb/3.12/concepts/data-structure/documents/_index.md),
+which allows a flexible data structure for each record. ArangoDB natively supports
+[graphs](arangodb/3.12/graphs/_index.md), letting you connect documents with
+edges to express relationships between records and build complex
+information networks. 
+
+### Data Retrieval
+
+You can query your data in various ways using the core database system.
+The native support for multiple data models lets you access information in
+different ways with a single query language called [AQL](arangodb/3.12/aql/_index.md).
+It has built-in support for aggregation, vector and full-text search, geo-spatial
+queries, and more.
+
+### Data Exploration
+
+You can visually explore and interact with your ArangoDB graphs through an
+intuitive web interface called the [Graph Visualizer](data-platform/graph-visualizer.md).
+It is part of the [Arango Data Platform](data-platform/_index.md) that builds on
+ArangoDB, extending it to a Kubernetes-native environment that unifies
+data management, monitoring, and automation.
+
+### Graph Queries
+
+Utilizing connected data starts with running simple [graph queries](arangodb/3.12/aql/graphs/_index.md).
+Using ArangoDB and its query language, you can determine the shortest paths between nodes as well as execute graph traversals. A traversal starts at a
+given node of a graph and follows the directly connected edges. The edges indicate
+what the next connected nodes are, and this discovery of neighbors can repeat.
+ 
+Graph queries can answer questions like **Who can introduce me to person X?**
+
+### Graph Analytics
+
+The next level of utilizing connected data in terms of complexity is to use
+graph analytics or graph algorithms to aggregate information about a graph.
+Unlike with graph queries, this involves the entire graph at once.
+
+Graph analytics can answer questions like **Who are the most connected persons?**
+
+Arango offers a [Graph Analytics](ai-suite/graph-analytics.md) solution as part
+of the [Arango AI Data Platform](data-platform/features.md) to run algorithms
+such as connected components, label propagation, and PageRank on your data.
+
+### GraphML
+
+For higher-level insights, you can use advanced graph-based data science.
+Applying machine learning on graphs lets you predict connections, get better
+product recommendations, and also classify nodes, edges, and graphs.
+
+GraphML can answer questions like:
+- **Is there a connection between person X and person Y?**
+- **Will a customer churn?**
+- **Is this particular transaction anomalous?**
+
+Arango's enterprise-ready, graph-powered machine learning capabilities are
+included in the [AI Suite](ai-suite/_index.md) as part of the
+Arango AI Data Platform. See [Arango GraphML](ai-suite/graphml/_index.md).
+
+### GraphRAG
+
+Generative AI often struggle with hallucinations because the connectedness of
+data is not properly or cleanly represented. GraphRAG is a technique that
+turbocharges GenAI applications using the power of graph relationships and
+vector embeddings.
+
+Arango's [GraphRAG](ai-suite/graphrag/_index.md) included in the
+[AI Suite](ai-suite/_index.md) is a turn-key solution to transform your
+organization's data into a knowledge graph and let everyone utilize the
+knowledge by asking questions in natural language.
+
+It automatically creates a knowledge graph from raw text by identifying and
+extracting entities and relationships within the data, groups and summarizes
+semantically similar entities, and stores everything in ArangoDB. When you ask a
+question, the large language model (LLM) is supplied with additional context
+from the knowledge graph, using lexical and semantic search. This enables
+accurate, context-aware intelligence grounded in enterprise data.

+## What are knowledge graphs?
+
+A knowledge graph can be thought of as a dynamic and interconnected network of
+real-world entities and the intricate relationships that exist between them.
+
+Key aspects of knowledge graphs:
+- **Domain-specific knowledge**: You can tailor knowledge graphs to specific
+  domains and industries.
+- **Structured information**: Makes it easy to query, analyze, and extract
+  meaningful insights from your data.
+- **Accessibility**: You can build a Semantic Web knowledge graph or using
+  custom data.
+
+LLMs can help distill knowledge graphs from natural language by performing
+the following tasks:
+- Entity discovery
+- Relation extraction
+- Coreference resolution
+- End-to-end knowledge graph construction
+- (Text) Embeddings
+
