AI Data Storage
Store, manage, and index documents with chunking and embedding for semantic search.
Purpose
AI Data Storage (RAG) is a component of the Latenode platform designed for storing and indexing text files, images, and other knowledge sources.
!!! tip This tool is primarily intended to be used in conjunction with the AI Agent — it provides documents in the form of chunks, which the agent can then use to generate responses.
Use cases include:
- Uploading and storing structured or unstructured content
- Generating embedding vectors for fast semantic search
- Running natural language search queries
- Connecting to the RAG Search node inside a scenario
How to Access
You can access this feature via Data Storage → AI Data Storage (RAG) in the left-hand side menu.
Creating Storage
Click Create Storage to open the setup modal:
Fill in the required fields: Storage Name, Chunk Size, Chunk Overlap
What are Chunk Size and Overlap?
- Chunk Size — the number of tokens in a single chunk. Smaller chunks provide higher accuracy but increase the total number of chunks.
- Chunk Overlap — the percentage of token overlap between neighboring chunks. Helps maintain context across them.
Managing Storage
Created storages are displayed in a table:
| Field | Description |
|---|---|
| Name | Storage name |
| Chunk Size | Number of tokens per chunk |
| Chunk Overlap | Overlap between chunks in % |
| Created | Creation date |
| Updated | Last updated date |
Uploading Files
Open a storage to access the upload interface. Drag-and-drop is supported.
After uploading:
- Each file is processed and indexed (status: Processing)
- Files are listed with size, upload date, and status
- Editing or downloading files is currently not supported
