Niche 6: AI & ChatGPT Integration
I Built a FREE AI Writing Assistant with n8n and OpenAI
I was paying for an AI writing tool, but I only used it for simple tasks like rephrasing sentences or brainstorming blog titles. I realized I could build my own for free. I created an n8n workflow with a webhook trigger. I connected this webhook to a simple web form. Now, I can type a prompt like “Rephrase this sentence to sound more professional,” paste my text, and hit submit. The workflow sends the prompt to the OpenAI API and displays the result on the screen. It’s my own personal, free-to-run AI writing assistant.
How to Triage and Summarize Your Inbox with AI Every Morning
My inbox used to give me anxiety. I built an AI-powered secretary to tame it. Every morning at 7 AM, an n8n workflow scans my unread emails. For each one, it asks the OpenAI API: “Is this email a newsletter, a promotion, a personal message, or an urgent task? Summarize it in one sentence.” The workflow then organizes the emails into a digest, grouped by category, and sends it to me in Slack. I can now grasp the state of my inbox in 60 seconds without getting bogged down in the details.
This n8n Workflow Uses AI to Draft Social Media Posts from a Blog URL
After writing a long blog post, the last thing I wanted to do was come up with clever social media copy to promote it. I built a workflow to do it for me. When I have a new blog post, I just give the URL to my n8n workflow. It scrapes the article’s content, sends it to an AI model, and prompts it to “Write 3 engaging tweets and 1 thoughtful LinkedIn post based on this article.” It then adds these generated posts as drafts in my social media scheduler, ready for a quick review.
I Built a Customer Support Bot That Solves 40% of Tickets Automatically
Our support team was swamped with repetitive questions like “How do I reset my password?” or “Where is my order?” I built an AI-powered “first line of defense.” When a new support ticket comes in, an n8n workflow first sends the question to an AI model that has been trained on our knowledge base. If the AI is highly confident it knows the answer, it replies to the customer directly. This single workflow now automatically resolves nearly 40% of our incoming tickets, freeing up our human agents to handle the truly complex issues.
How to Use AI to Personalize Your Cold Emails (Without Sounding Like a Robot)
My cold emails were generic and getting ignored. I used n8n and AI to add a personal touch at scale. My workflow takes a prospect’s name and company URL. It scrapes their company’s “About Us” page and sends the text to an AI with the prompt: “Find one interesting fact or mission statement from this text and write a single, genuine-sounding sentence about it.” It then inserts this sentence as the opening line of my cold email. The personalized intros have dramatically increased my reply rates.
This Workflow Analyzes Customer Feedback Sentiment with AI
We collect a lot of customer feedback, but reading through it all to gauge the general mood was time-consuming. I built a sentiment analysis workflow. Now, whenever a new piece of feedback is submitted via a survey or form, an n8n workflow sends the text to an AI model. It asks, “Is the sentiment of this feedback positive, negative, or neutral?” The workflow then logs the feedback and its sentiment score in a spreadsheet. This gives us a real-time, quantitative dashboard of customer happiness.
I Built a “Content Idea Generator” That Never Runs Out of Ideas
I used to stare at a blank page, struggling to come up with new blog post ideas. I built a machine to do it for me. My n8n workflow is connected to the RSS feeds of several industry blogs and news sites. Every day, it takes the titles of the latest articles, sends them to an AI, and prompts it: “Based on these current trends, generate a list of 10 surprising or controversial blog post titles for a [my industry] audience.” The results are sent to my “Ideas” board in Trello.
How to Automatically Generate Alt Text for Your Images with AI
Writing descriptive alt text for all our website images was a tedious but important accessibility task that we often skipped. I automated it. I built an n8n workflow that triggers whenever a new image is uploaded to our media library. The workflow sends the image to a vision-enabled AI model (like GPT-4 Vision) and prompts it: “Write a concise, descriptive alt text for this image.” The AI returns the text, and the workflow then updates the image’s alt text field in our CMS automatically.
This n8n Workflow Transcribes Audio/Video Files and Provides a Summary
I have hours of interview recordings and webinar footage that I needed to pull insights from. I built a workflow to process them. I can now drop an audio or video file into a specific Google Drive folder. This triggers an n8n workflow that sends the file to an AI transcription service like AssemblyAI. Once the transcript is ready, it sends the full text to another AI prompt: “Summarize the key topics and action items from this conversation.” The final summary is then emailed to me.
I Built an AI-Powered “Meeting Assistant” That Takes Notes For Me
I find it hard to actively participate in a meeting while also taking detailed notes. So I built an AI assistant to do it for me. I use a tool to record and transcribe my meetings. As soon as the meeting ends, a webhook sends the full transcript to my n8n workflow. The workflow then prompts an AI to identify the key decisions made, list all the action items (and who they were assigned to), and write a concise summary. It then posts these organized notes to our shared Notion page.
How to Use AI to Rephrase Your Content for Different Platforms
The same message doesn’t work on Twitter, LinkedIn, and in an email. I built a workflow to adapt my content. I can write a core message and give it to my n8n workflow. The workflow then uses a series of AI prompts to tailor it for different channels. It asks the AI to “turn this into a short, punchy tweet,” “expand on this for a professional LinkedIn post,” and “rewrite this as a friendly, informal email.” It allows me to maintain a consistent message while respecting the norms of each platform.
This Workflow Uses AI to Categorize Incoming Leads and Support Tickets
When a new lead or support ticket arrived, someone had to manually read it and assign it to the right department (e.g., Sales, Tech Support, Billing). I automated this triage process. Now, when a new message comes in, an n8n workflow sends the text to an AI model with a simple prompt: “Based on this text, categorize it as one of the following: Sales Inquiry, Technical Support, Billing Question, or Other.” The workflow then automatically adds the correct tag and routes the ticket to the appropriate team.
I Built a “Grammarly” Clone Using n8n and the OpenAI API
I wanted to check my writing for grammar and style without sending my data to a third-party service. I built my own personal “Grammarly.” I created a simple web interface where I can paste my text. This sends the text to an n8n workflow. The workflow forwards the text to the OpenAI API with a detailed prompt: “Act as a strict editor. Proofread the following text for any grammatical errors, spelling mistakes, or awkward phrasing. Provide a list of suggested changes.” The suggestions are then displayed back on the web page.
How to Generate Product Descriptions for Your E-commerce Store with AI
Writing unique and compelling product descriptions for hundreds of products was a huge bottleneck for my e-commerce store. I used AI to break the logjam. I created an n8n workflow that takes a product’s name and a few bullet points about its features from a spreadsheet. It then feeds this information into a crafted AI prompt: “Write a 150-word, persuasive e-commerce product description for a [product name] with these features: [features].” The workflow then writes the generated description back into the spreadsheet, ready for upload.
This n8n Workflow Creates AI-Generated Images for My Blog Posts
I needed unique featured images for my blog posts but didn’t have the budget for stock photos or a designer. I built an image generator. When I have a title for a new blog post, I give it to my n8n workflow. The workflow sends the title to an AI model (like DALL-E or Midjourney via their API) with a prompt like “Create a vibrant, abstract digital art image representing the concept of ‘[blog post title]’.” The generated image is then saved to my media library, ready to be used.
I Built a Research Assistant That Scours the Web and Summarizes Findings
When I need to research a new topic, I used to spend hours sifting through Google results. Now, I delegate it to my AI research assistant. I give my n8n workflow a research topic, like “the future of renewable energy.” The workflow performs a series of targeted Google searches, scrapes the text from the top 5 articles, and then feeds all that text into a large context AI model. The final prompt is: “Based on these articles, write a detailed summary of the key trends and findings.” The summary is then emailed to me.
How to Use AI to Write SQL Queries or Code Snippets on the Fly
I know what data I want from our database, but I’m slow at writing the correct SQL query. I built a “text-to-SQL” bot. I have a Slack command where I can write in plain English: “/sql-query show me all users from California who signed up last week.” An n8n workflow takes this text, combines it with our database schema information, and sends it to an AI with the prompt: “Write a valid SQL query for this request.” The workflow then posts the generated SQL code back to me in Slack.
This Workflow Translates Website Content into Multiple Languages with AI
We wanted our website to be accessible to a global audience but couldn’t afford professional translation services for every page. I built an AI-powered translation workflow. When we publish a new page or blog post in English, an n8n workflow is triggered. It takes the page’s content, sends it to a high-quality translation API like DeepL, and gets back the Spanish, French, and German versions. It then creates new pages in our CMS with the translated content, making our site multilingual automatically.
I Built an AI-Powered Chatbot for My Website Using n8n and Telegram
I wanted a simple chatbot on my website to answer basic questions, but the available platforms were too expensive. I built one myself. I embedded a Telegram web chat widget on my site. This chat is connected to an n8n workflow. When a user sends a message, it gets piped to the OpenAI API, which has been given our company’s information as context. The AI’s response is then sent back to the user via the Telegram bot. It’s a fully functional AI chatbot that I built for pennies.
How to Create Personalized AI-Generated Video Scripts
We wanted to create personalized video messages for our top clients but didn’t have time to write and record hundreds of them. I built a script generator. My n8n workflow takes a client’s name, their company, and a recent success they had with our product. It then feeds this into a detailed AI prompt: “Write a short, enthusiastic 30-second video script congratulating [Client Name] from [Company] on their success with [achievement].” The generated script is then sent to our sales team, ready for them to record.
This Workflow Uses AI to Score Leads Based on Their Initial Inquiry
When a new lead filled out our “contact us” form, it was hard to tell if they were a hot prospect or just a tire-kicker. I built an AI lead scorer. Now, when a new form is submitted, the n8n workflow sends the content of their message to an AI model. It asks the AI, “Based on this message, rate the user’s buying intent on a scale of 1-10.” The workflow then adds this “Intent Score” to a field in our CRM, helping our sales team prioritize who to call first.
I Built a “Plagiarism Checker” for My Content Team with n8n
To protect our site’s SEO, I needed to ensure all the articles from our freelance writers were original. I built a simple plagiarism checker. When a writer submits a new article in a Google Doc, it triggers an n8n workflow. The workflow takes the text, breaks it into paragraphs, and performs a series of exact-match Google searches for each paragraph. If it finds a high percentage of matches, it flags the document and sends an alert to our editor for a manual review.
How to Fine-Tune an AI Model Using Your Own Data via n8n
Generic AI models are good, but I wanted one that knew my company’s specific voice and style. This guide explains how you can use n8n to automate the process of fine-tuning an AI model. We’ll show you how to set up a workflow that gathers examples of your company’s best writing (from your blog, support docs, etc.), formats it into the required training file structure, and then uses the OpenAI API to kick off a fine-tuning job. The result is a custom AI model that truly sounds like you.
This Workflow Extracts Key Information from Resumes and PDFs
Our HR team was spending hours manually reading resumes and entering candidate information into our applicant tracking system. I built a workflow to do it for them. Now, when a new resume is emailed in, the n8n workflow receives the PDF. It sends the file to an AI document-parsing service. The AI extracts structured data like name, contact info, work experience, and skills. The workflow then uses this data to automatically create a complete candidate profile in our HR system.
I Built an “Explain It To Me Like I’m 5” AI Bot for Complex Topics
Sometimes I read a technical article or a dense report and struggle to grasp the core concept. I built a “simplifier” bot. I can send a block of text or a URL to my n8n workflow. It takes the content and sends it to an AI with a simple but powerful prompt: “Explain the following concept to me like I’m 5 years old.” The AI’s simplified explanation is then sent back to me. It’s an incredibly useful tool for cutting through jargon and understanding complex ideas quickly.
How to Automate Your SEO Meta Descriptions with AI
Writing unique meta descriptions for hundreds of product and blog pages is a classic SEO chore. I automated it. I have an n8n workflow that can scan my entire website. For any page that is missing a meta description, it takes the page’s main content, sends it to an AI, and prompts it: “Write a compelling, 155-character meta description for a page with this content.” The workflow then uses my CMS’s API to update the page with the generated description.
This Workflow Drafts Responses to Customer Reviews (Both Positive and Negative)
Responding to every customer review is important for our brand image, but it takes time. I built a “response drafter” bot. When a new review is posted for our business, a webhook notifies n8n. The workflow sends the review text and the star rating to an AI. It then uses a conditional prompt: if the review is positive, it asks for a “friendly and grateful response.” If it’s negative, it asks for an “apologetic and helpful response.” The drafted reply is then sent to our team for a quick edit and approval.
I Built an AI Story Generator for My Kids’ Bedtime Stories
My kids always ask for a new bedtime story, and sometimes my imagination runs dry. I built a story generator with n8n. I created a simple form where my kids can choose a main character (e.g., a brave knight), a setting (a spooky castle), and a magical object (a talking sword). The n8n workflow takes these inputs and weaves them into a detailed prompt for an AI model. The result is a unique, 5-minute bedtime story, which I can then read to them from my phone.
How to Use AI to Brainstorm Domain Names and Taglines
Coming up with a great name for a new project is one of the hardest parts. I built an AI brainstorming partner. I can give my n8n workflow a short description of a new product or company. The workflow then uses a series of AI prompts to generate ideas. It asks for “ten catchy, one-word .com domain names,” “ten clever two-word brand names,” and “five memorable taglines” related to the project description. It’s a fantastic way to kickstart the creative process.
This Workflow Creates Weekly Business Reports with AI-Generated Insights
My old weekly business reports were just a collection of data points. I built a new workflow that provides actual insights. The workflow gathers our key metrics (sales, website traffic, ad spend). But then, it sends all this data to an AI model with a prompt: “You are a business analyst. Based on this weekly data, what are the most significant trends, what is a potential risk, and what is the biggest opportunity? Write a short summary of your analysis.” This AI-generated insight is now the most valuable part of our weekly report.
I Built a “Fake Data” Generator for Testing and Development
When building a new feature, our developers needed realistic-looking data to test it, but using real customer data was a privacy risk. I built a fake data generator. A developer can send a request to an n8n workflow like “I need 100 fake user profiles with names, addresses, and email addresses.” The workflow then uses an AI model to generate this data, ensuring it looks real but is completely fabricated. This allows our team to test thoroughly without compromising user privacy.
How to Connect a Local AI Model (LLM) to n8n for Ultimate Privacy
I wanted to use the power of large language models for sensitive company data, but I couldn’t send that data to a third-party API like OpenAI. This guide shows how to run an open-source AI model (like Llama 3) locally on your own server, and then connect it to your n8n workflows. By calling your own local AI, you get the same powerful capabilities for summarization, analysis, and generation, but with the guarantee that your sensitive data never leaves your own infrastructure.
This Workflow Helps Me Prepare for Interviews by Generating Practice Questions
When I have an upcoming job interview, I want to be as prepared as possible. I built an interview prep workflow. I give the n8n workflow the job description for the role I’m applying for. The workflow sends the description to an AI and prompts it: “Based on this job description, generate a list of 15 challenging behavioral and technical interview questions that an interviewer might ask.” It’s like having a personal interview coach helping me anticipate the questions and prepare my answers.
I Built an AI-Powered “Fact Checker” for My Content
To maintain our brand’s credibility, I wanted to ensure our content was accurate. I built a simple AI fact-checker. When a new article is written, my n8n workflow extracts all the factual claims and statistics from the text. For each claim, it performs a targeted Google search and scrapes the top results. It then asks an AI to compare the claim with the search results and flag any inconsistencies. It’s not foolproof, but it acts as a valuable first-pass check for our editors.
How to Create a Knowledge Base Search Bot with AI Embeddings
Our company’s knowledge base was hard to search. You had to know the exact keywords. I built a smarter search bot using AI embeddings. An n8n workflow first “indexed” our entire knowledge base by converting each article into a set of vectors. Now, when a user asks a question like “How do I change my billing info?”, another workflow converts their question into a vector and finds the most semantically similar articles in our database, providing much more relevant results than a simple keyword search.
This Workflow Turns My Jumbled Notes into a Coherent Document
My personal notes are often a chaotic mix of bullet points, half-formed sentences, and random thoughts. I built a workflow to bring order to the chaos. I can paste my jumbled notes into a form. The n8n workflow sends the text to an AI with the prompt: “Take these disorganized notes and structure them into a coherent document. Use clear headings, bullet points, and well-written paragraphs to organize the information logically.” The output is a clean, readable document that I can actually use.
I Built a Diet and Meal Planner with AI and n8n
I wanted a personalized meal plan but didn’t want to pay for a nutritionist. I built an AI one. I have a form where I enter my dietary goals (e.g., “high protein, low carb, 2000 calories per day”) and any foods I dislike. An n8n workflow sends this information to an AI with a detailed prompt asking it to generate a full 7-day meal plan, complete with recipes and a consolidated grocery list. It’s a powerful and completely customized tool for managing my diet.
How to Use AI to Analyze Your Competitors’ Marketing Copy
I wanted to understand what messaging was resonating in my industry. I built a workflow to analyze my competitors’ marketing. The workflow scrapes the homepage copy from my top five competitors’ websites. It then sends all this text to an AI model and asks it a series of questions: “What are the most common value propositions? What is the prevailing tone of voice (e.g., playful, professional)? What pain points are they targeting?” The analysis gives me a clear overview of the competitive landscape.
This Workflow Creates Custom Excel Formulas with a Simple English Prompt
I often know what I want to do in Excel or Google Sheets, but I don’t know the right formula to use. I built a “formula generator” bot. I can go to a Slack channel and type “/excel-formula sum column C if column A says ‘Sales’.” An n8n workflow takes my plain English request, sends it to an AI model trained on writing formulas, and gets back the correct formula (=SUMIF(A:A, “Sales”, C:C)). It then posts the formula back in Slack.
I Built an AI Role-Playing Game Master Using n8n
My friends and I love Dungeons & Dragons, but we don’t always have someone available to be the Dungeon Master (DM). I built an AI DM. Using n8n and Telegram, we can interact with an AI that has been prompted to act as a creative and fair game master. It describes the world, presents challenges, and responds to our actions. n8n manages the “state” of the game (like player health and inventory), making for a surprisingly immersive and endlessly available role-playing experience.
How to Automate A/B Testing of Ad Copy with AI
Writing multiple versions of ad copy for A/B testing is time-consuming. I used AI to automate it. My n8n workflow takes a single core message for a new ad campaign. It then sends this message to an AI with a prompt: “Generate 5 different versions of ad copy based on this core message. Make one version funny, one focused on scarcity, one focused on benefits, one that asks a question, and one that is very direct.” The workflow then automatically creates a new A/B test in our ad platform with these five variants.
This Workflow Creates Personalized Learning Paths for New Employees
When a new employee joined, we used to just give them a long list of documents to read. It wasn’t very effective. I built a personalized learning path generator. Based on the new hire’s role (e.g., “Sales,” “Engineering”), an n8n workflow prompts an AI to create a structured, week-by-week learning plan. The plan includes specific articles to read, videos to watch, and people to meet, all tailored to their role. It provides a much more guided and effective onboarding experience.
I Built an AI “Dream Interpreter” Just for Fun
I thought it would be a fun and slightly weird project to build an AI dream interpreter. I set up an n8n workflow connected to a simple web form where I can write down the details of a dream I had. The workflow sends the text to an AI with a creative prompt: “You are a dream analyst who interprets dreams through a symbolic and psychological lens. Provide a thoughtful interpretation of the following dream.” The results are often surprisingly insightful and always entertaining.
How to Create AI-Powered Data Visualizations
I had a spreadsheet full of data, but I didn’t know the best way to visualize it. I built a workflow to help. I can upload a CSV file to my n8n workflow. The workflow analyzes the headers and a sample of the data, then asks an AI: “Given this data, what would be the most effective type of chart to visualize it (e.g., bar chart, line graph, scatter plot)?” It then uses a charting library and the AI’s suggestion to automatically generate a PNG of the chart and sends it to me.
This Workflow Helps Me Write Better Code by Suggesting Refinements
Sometimes my code works, but I know it could be cleaner or more efficient. I built a “code review” bot. I can paste a snippet of my code into a form that triggers an n8n workflow. The workflow sends the code to an AI model with the prompt: “Act as a senior software engineer. Review the following code. Is there any way to make it more efficient, more readable, or more robust? Suggest specific improvements.” The AI’s feedback helps me learn and improve my programming skills.
I Built an AI “Devil’s Advocate” to Challenge My Business Ideas
When I get excited about a new business idea, I can suffer from confirmation bias. I built an AI to be my “devil’s advocate.” I can write out my new idea and submit it to my n8n workflow. The workflow prompts an AI to “Read this business idea and act as a skeptical investor. Challenge the core assumptions. What are the biggest risks and potential failure points? What hard questions should I be asking myself?” This automated critique forces me to think more critically and strengthen my plans.
How to Connect n8n to Hugging Face Models for Specialized AI Tasks
OpenAI is great for general tasks, but sometimes you need a specialized model for something specific, like sentiment analysis or audio processing. This guide shows how to use n8n to connect to the thousands of open-source models available on Hugging Face. We’ll walk through how to use the Hugging Face node to perform tasks that are difficult or expensive with general-purpose models, unlocking a whole new world of powerful, specialized AI capabilities for your workflows.
This Workflow Summarizes Long YouTube Videos so I Don’t Have to Watch Them
I often want the key information from a long lecture or interview on YouTube, but I don’t have an hour to watch it. I built a video summarizer. I can give my n8n workflow a YouTube URL. The workflow uses a service to get the full transcript of the video. It then sends the entire transcript to an AI with the prompt: “This is a transcript of a YouTube video. Please provide a detailed summary of the main arguments, key takeaways, and any actionable advice.” The summary is then sent to me.
I Built a System to Automatically Tag and Organize My Photo Library with AI
My digital photo library was a mess of thousands of unorganized files. I built a workflow to automatically tag them. The workflow iterates through my photo library, and for each image, it sends it to a vision-enabled AI model. It prompts the AI to “analyze this image and return a list of relevant keywords or tags, including objects, settings, and people.” The workflow then writes these keywords into the image’s metadata, making my entire library searchable for the first time.
The Future of Work: How n8n + AI Will Replace Your Most Hated Tasks
This isn’t a “how-to” but a forward-looking vision piece. It tells the story of a fictional marketing manager, “Jane,” and how her job changes over a year as she learns to combine n8n and AI. We see her go from manually building reports to having AI analyze the data for her. We see her delegate tedious writing tasks to her AI assistant. The story illustrates that the future of work isn’t about AI replacing people, but about people using tools like n8n and AI to automate drudgery and elevate their roles to be more strategic and creative.
