Dive into the world of automation with n8n and AI by building three beginner-friendly workflows! This breakdown will show you step-by-step how to connect various services, deploy powerful AI models, and create automation systems that streamline tasks. By the end, you’ll master the fundamentals of workflow creation and integration while gaining hands-on experience with cutting-edge tools.
🚀 Why This Matters
Automation allows you to offload repetitive tasks, save countless hours, and ensure consistency. With n8n, a tool that connects various platforms and automates workflows, the possibilities are endless. Whether you’re organizing customer support, generating content, or developing custom AI agents, you’ll want these skills at your fingertips.
🧠 Workflow 1: Build a Retrieval-Augmented Generation (RAG) Chatbot
💡 Core Idea:
Create a chatbot that can look up specific answers from your database when it doesn’t know the answer—leveraging retrieval-augmented generation (RAG) and vector databases.
🧩 How It Works:
- Understand RAG: It combines question-answering with a reference system. If the AI doesn’t know something, it searches a vector database for relevant content.
- What’s a Vector Database?
- Think of it as mapping words or sentences into a dimensional space based on their meanings. 🐕 Words like “dog,” “cat,” or “wolf” get stored near each other. 🍎 “Apple” and “banana” are stored elsewhere since they’re fruits.
- When a question is asked, it’s converted into this space to find the best match.
⚙️ Steps to Build:
- Use Google Drive to upload files (like policies or FAQs).
- Break your document into small, chunked pieces (e.g. 1,000-character text snippets).
- Use an embeddings model (e.g. OpenAI’s
text-embedding-ada-002) to turn those text chunks into numbers. - Store these data points into a vector database like Pinecone.
- Set up a chatbot that queries the database when needed.
Example✨:
- Upload a store policy document.
- Ask: “What’s your warranty policy?”
- The chatbot retrieves the relevant section from the document stored in Pinecone.
📌 Quick Tip:
In Pinecone, organize your data by 'namespace' to keep FAQ data separate from others—just like folders! 🌐
🛠️ Workflow 2: Automate Customer Support with AI
💡 Core Idea:
Build an AI-driven inbox assistant that identifies customer support emails and automates replies. 📧
🧩 How It Works:
- Email Trigger: Automatically detect new incoming Gmail messages.
- Classify Messages: Use AI to label emails as “Customer Support” or “Other.”
- Pull Data to Respond: Feed message details into the RAG workflow to generate personalized responses.
⚙️ Steps to Build:
- Connect Gmail:
- Use Google Cloud to enable the Gmail API.
- Provide proper OAuth credentials to access your inbox.
- Categorize Emails:
- Apply a Text Classifier node to label emails as “Support” or “Non-support.”
- Train the AI with examples of common ticket phrases (e.g., “What’s your pricing policy?”).
- Reply Automatically:
- For classified emails, fetch relevant policy data using the vector database.
- Generate a reply using AI (e.g., via OpenAI or Claude).
- Update Status:
- Add a Gmail label or color-tag for resolved conversations.
Example✨:
- An email asks: “What is your privacy policy?”
- The workflow retrieves privacy FAQs and crafts a response:
“Hi! Here’s our policy: [Data Protection Overview]. For details: [Link].”
📌 Quick Tip:
Keep it friendly by adding emojis and custom sign-offs, like “Warm regards, [Your AI Assistant].” 🎊
✍️ Workflow 3: Automatic LinkedIn Content Creator
💡 Core Idea:
Generate fresh LinkedIn posts every day based on pre-defined topics. Kickstart your brand-building efforts effortlessly. 🌟
🧩 How It Works:
- Schedule daily content generation using a Google Sheet as your task manager.
- Automatically search the web for material related to your topic.
- Leverage AI writing models to summarize findings and create engaging posts.
⚙️ Steps to Build:
- Define Your Topic List:
- Create a Google Sheet with three columns:
Topic(e.g., “AI Image Generation”),Status(set as “To-Do”),LinkedIn Content(leave blank for AI to fill later).
- Fetch Tasks 🧾:
- Use Google Sheets API and filter rows where the
Status= “To-Do.”
- Conduct Research 🔍:
- Call Tavily API to pull relevant web searches around the topic (limit to key articles).
- Generate Content:
- Use an AI agent to process articles and craft a LinkedIn post.
- Write Back Results 💾:
- Update the original Google Sheet to mark the
Statusas “Complete” and fill in the generated content.
Example✨:
- Topic: “AI Image Generation”
- Output:
“The creative revolution is here with AI-powered tools like [X]!” 🖌️🎨 Include hashtags like#AIand#Innovation.
📌 Quick Tip:
Set this workflow on auto-schedule to post at a specific time for a seamless daily routine.
