Chat with PDF / MD / Text Files using GraphRAG (no vector store needed)

# Step 1: Upload Your PDF / MD / Text Files to InfraNodus GraphRAG

## Copy your PDF files to a Google drive and then upload them to your InfraNodus knowledge graph

### InfraNodus visualizes your text as a knowledge graph, showing the main topics and ideas inside. It also provides API access to the knowledge graph, so you can use it as a knowledge base instead of the complex vector store setup

1. You need an [InfraNodus](https://infranodus.com) account to use this workflow. Get the API key at [https://infranodus.com/api-access](https://infranodus.com/api-access)
2. Also, specify the **name of the graph** you want to save the files to in the InfraNodus HTTP node
3. When the workflow finishes running, you can get a visualization of your knowledge base at [https://infranodus.com/your_user_name/your_graph_name/edit](https://infranodus.com/your_user_name/your_graph_name/edit)
