# Interact with existing Sub-Graphs

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.
