# Interact with existing Sub-Graphs

This section provides an overview of how users can expect to interact with and query existing subgraphs created and hosted by the GraphAI Team.

One of the first features available to Closed Beta users is the ability to explore and query **predefined sub-graphs** created by the GraphAI team. These sub-graphs act as curated datasets, each focused on a specific onchain activity such as token transfers, liquidity pool movements, or wallet behavior.

By starting with existing sub-graphs, users can immediately experience how GraphEngine transforms raw blockchain data into structured, queryable knowledge. You will be able to use **natural language prompts** or GraphQL queries to pull insights, test different types of questions, and see how responses are structured.

This approach ensures that even without creating a custom subgraph, you can begin experimenting right away. It also provides a foundation for understanding how sub-graphs are built and what kind of insights they unlock—knowledge that will be invaluable once you move on to creating your own.
