Needle RAG Integration for n8n: Supercharge Your Workflows with RAG

Today I'm excited to share how you can connect Needle AI with n8n to build powerful automated workflows that tap into all your organization's knowledge. This integration opens up new possibilities for information discovery and automation.

What is Needle AI?

Needle AI is a Knowledge Threading™ platform that helps you find information in seconds across all your connected data sources. According to McKinsey, employees spend a staggering 1.8 hours every day searching for information. Needle eliminates this waste by:

• Connecting your data sources: Google Drive, Dropbox, Confluence, and more

• Providing AI-powered search: Find exactly what you need with natural language queries

• Delivering answers instantly: Say goodbye to communication bottlenecks and information silos

• Enabling AI agent creation: Build powerful AI agents that interact with your data

Introducing the n8n Integration

If you're already using n8n for your automation workflows, you'll be thrilled to know that Needle AI now integrates seamlessly as a custom node. For those unfamiliar with n8n, it's an open-source workflow automation tool that connects apps, services, and APIs.

The Needle node for n8n unlocks powerful capabilities:

• Collection Management: List, create, and manage your Needle collections

• Semantic Search: Perform intelligent searches across your documents

• File Management: Add files to collections directly through your workflows

• Workflow Automation: Build complex knowledge workflows with Needle at the center

Setting Up the Integration (Self-Hosted Only)

Note: Currently, the Needle node is available for self-hosted n8n instances only. If you'd like to see it in the cloud version, please upvote our thread (linked below).

The setup process is straightforward:

1. Install pnpm (if you haven't already):

npm install -g pnpm

1. Navigate to your n8n custom nodes directory:

cd ~/.n8n/custom/

1. Install the Needle node:

pnpm add @needle-ai/needle-n8n-nodes

1. Start n8n to load the new nodes:

n8n start

Once installed, you'll find the Needle nodes in your n8n node panel by searching for "Needle". The nodes include operations for collections, files, and search functionality.

Real-World Use Cases

Let's explore some practical applications of the Needle AI and n8n integration:

1. Automated Support Workflow

Imagine this flow:

• A new support ticket arrives in your helpdesk system

• n8n captures the customer's question

• Your workflow automatically searches Needle for relevant information

• The perfect answer is retrieved with proper sources and references

• This information passes through an AI service for refinement

• A comprehensive response gets delivered to your support team in Slack

This workflow reduces response times, ensures accuracy, and frees your support team to focus on complex issues.

2. Smart Documentation Updates

Keep your knowledge base fresh:

• When your team updates a document in Google Drive

• n8n detects the change and adds it to your Needle collection

• Your entire organization immediately has access to the latest information

• No more outdated knowledge or version confusion

3. Sales Enablement

Empower your sales team:

• Sales reps input customer needs into a form

• n8n triggers a Needle search across all sales materials

• The most relevant pricing, decks, and case studies are automatically compiled

• Everything is packaged into a personalized email for the prospect

Getting Started with a Basic Workflow

Here's a simple example to get you started:

1. Set up a trigger (HTTP, Scheduler, etc.)

2. Add a Needle node:

   • Select "Collection" as the resource

   • Choose "Search" as the operation

   • Enter your Collection ID

   • Provide a search query (e.g., "latest quarterly financial reports")

3. Process the results with a function node or send them to another service

The Needle node will return comprehensive search results including the content, source files, and relevance scores.

Support for Cloud Version

Currently, the Needle node is available as a custom node for self-hosted n8n instances. To get it added to the n8n cloud version, n8n requires a significant number of user requests.

Help us make it happen! If you'd like to use Needle in n8n cloud, please upvote our thread. Once there's sufficient demand, n8n will consider adding Needle to their cloud offering.
