+[Stardog](https://www.stardog.com) is an enterprise knowledge graph platform that enables organizations to unify, query, and analyze their data.
+
+Give agents a tool to:
+
+- Ask natural language questions and get hallucination-free answers from your enterprise knowledge graph database
+- Generate SPARQL queries from natural language
+- Query and analyze structured data using semantic reasoning
+- Access enterprise data through a conversational interface
+
+### How it works
+Stardog provides knowledge graph infrastructure that combines data integration with natural language processing:
+
+1. Give your agent access to enterprise knowledge graphs
+2. Query data using natural language through Voicebox
+3. Get accurate, grounded answers backed by your data
+
+## Installation and Setup
+
+Check out the [tool documentation](/oss/integrations/tools/stardog) to see how to set up and use the available tools.

+>[Stardog](https://www.stardog.com) is an enterprise knowledge graph platform that enables organizations to unify, query, and analyze their data.  
+> This integration package provides langchain tools and runnables for interacting with Stardog Voicebox, which is a natural language answering agent providing hallucination-free insights from your enterprise data.
+
+## Overview
+
+The Stardog LangChain integration package provides the following tools for working with Stardog Voicebox:
+- `VoiceboxAskTool` - Ask questions and get natural language answers
+- `VoiceboxGenerateQueryTool` - Generate SPARQL queries from natural language
+- `VoiceboxSettingsTool` - Retrieve Voicebox application settings
+
+All tools support both synchronous and asynchronous execution modes, making them suitable for various application architectures.
+
+For complete details, see the [GitHub repository](https://github.com/stardog-union/stardog-langchain).
+
+## Setup
+
+### Installation
+
+```bash
+pip install langchain-stardog
+```
+
+### Prerequisites
+
+- A [Stardog Cloud](https://cloud.stardog.com) account
+- A Voicebox application configured with your data
+- A Voicebox API token
+
+### Getting Your API Token
+
+1. Log in to [Stardog Cloud](https://cloud.stardog.com)
+2. Click on your profile icon and select **Manage API Keys**.
+3. Create a new application and generate a secret.
+4. Copy the API token and keep it secure.
+5. For more details, see Stardog Voicebox API access.
+
+### Credentials
+
+Set your API token as an environment variable:
+
+```python
+import getpass
+import os
+
+if not os.environ.get("SD_VOICEBOX_API_TOKEN"):
+    os.environ["SD_VOICEBOX_API_TOKEN"] = getpass.getpass("Enter your Voicebox API token: ")
+```
+
+Optional environment variables:
+
+```python
+os.environ["SD_VOICEBOX_CLIENT_ID"] = "my-app"  # Client identifier (default: VBX-LANGCHAIN)
+os.environ["SD_CLOUD_ENDPOINT"] = "https://cloud.stardog.com/api"  # Custom endpoint (optional)
+```
+
+## Instantiation and Examples
+
+### VoiceboxAskTool
+
+Ask natural language questions relevant to the knowledge graph configured with your API token, and receive hallucination-free answers.
+
+```python
+from langchain_stardog.voicebox import VoiceboxAskTool
+
+# Tools automatically load credentials from environment variables
+ask_tool = VoiceboxAskTool()
+
+# Ask a question
+result = ask_tool.invoke({"question": "What are all flights from San Francisco to New York?"})
+print(result)
+# Returns: Natural language answer
+```
+
+### VoiceboxSettingsTool
+
+Retrieve Voicebox application configuration and metadata.
+
+```python
+from langchain_stardog.voicebox import VoiceboxSettingsTool
+
+settings_tool = VoiceboxSettingsTool()
+
+# Get application settings
+settings = settings_tool.invoke({})
+print(settings)
+# Returns: Configuration details like data sources, schema info, and capabilities
+```
+
+### VoiceboxGenerateQueryTool
+
+Generate SPARQL queries for the natural language question without executing them.
+
+```python
+from langchain_stardog.voicebox import VoiceboxGenerateQueryTool
+
+query_tool = VoiceboxGenerateQueryTool()
+
+# Generate a SPARQL query
+query = query_tool.invoke({"question": "Which flights are delayed by more than 30 minutes?"})
+print(query)
+# Returns: Generated SPARQL query without executing it
+```
+
+Refer to the [Examples](https://github.com/stardog-union/stardog-langchain?tab=readme-ov-file#examples) section for different ways to use these tools and runnables.
