 title: Data Overview
 ---
 
-The RPC, data indexers, Hubble, and Horizon are platforms or tools that facilitate communication between users and applications and the Stellar network. With these various platforms, users can query network data, submit transactions, and interact with smart contracts without needing to understand the low-level details of Stellar Core.

+
+There are several products to choose from when interacting with the Stellar Network, and each one is optimized for different access patterns, so it's important to choose the right tool based on your specific use-case. These tools allow users to query network data, submit transactions, and interact with smart contracts without needing to understand the low-level details of Stellar Core.
 
 This section will walk you through the differences between the various platforms and tools, what platform or tool is best for what use case, and then link to their various documentation locations.
 
+- **[RPC](#rpc)** - live network gateway
+- **[Horizon](#horizon)** - API for network state data
+- **Galexie** - exports raw ledger metadata files

 ## [RPC](./rpc/README.mdx)
 
 The RPC primarily provides information that the Stellar network currently has in view, i.e., **the current state**, which includes the current balances of all accounts, the current state of smart contracts, and any other relevant information that constitutes the present condition of the blockchain. It has the ability to send a transaction to the network and query the network for the status of previous transactions (subject to the retention window of seven days, transactions older than that will return a `NOT_FOUND` response). The RPC is meant to be simple, minimal, and scalable.
