What’s On My Mind: What The Heck is n8n And Why Are AI Nerds Obsessed With It?
This week, let’s cover a topic that’s super hot right now in the world of generative AI but is not super well explained: the automation system n8n.
Maybe you’ve heard of it, maybe you haven’t. If you’ve seen screenshots of things that look kind of like Zapier, and a bunch of frothing and foaming at the mouth about agentic AI on LinkedIn, you’ve probably seen n8n.
Part 1: What is n8n?
In a nutshell, n8n is workflow automation software. You and I use it to automate tasks, from the mundane to the exotic. If you’ve ever played games where you have to connect different nodes together (like that one game where you have to connect pipes to get water flowing), or build modular structures (like in SimCity/SimTower), n8n is a natural evolution of that kind of automation.
What makes it different and useful in many ways is that n8n has both no-code and high-code options. Hardcore coders can use it and write in its native language (JSON) to quickly develop very elaborate workflows and automations, as well as write their own modules and nodes for it, making it infinitely extensible. Non-technical people can use its interface and pre-made connectors and blocks (called nodes) to piece together workflows.
By no means is n8n a unique idea; tools like IBM’s Node-RED and tools like Zapier have offered low-code/no-code solutions for well over a decade.
What makes n8n different from those options is that it’s easier to use than a system like Node-RED, and because it’s open-source, you can run it for free on your computer instead of paying for the cloud service. (that said, companies probably want to pay for the cloud version unless you have specific reasons not to, like data privacy) Itโs not the only company and product in the field; Zapier and Make (formerly Integromat) and a few others also play similar roles.
Part 2: Why is everyone talking about n8n?
The main reason that the nerds are all talking about n8n is automation of AI. N8n as an ecosystem makes it very easy to tie generative AI into your existing workflows in ways that donโt require a lot of coding. Itโs the middleware that connects AI to other things – and thatโs the critical thing you need to know about it.
One of the things Iโve said for a while about generative AI is that while itโs a powerful tool, itโs like the engine of the car. The engine of a car is critical to its operation, but without the rest of the car, itโs not terribly helpful. No one drives down the road sitting on an engine block. You drive down the road in a car, with wheels, a body, seats, a steering wheel – you get the idea.
The challenge is for a lot of us, building the rest of the car is the challenge. Many folks are still doing a ton of copy pasting into and out of ChatGPT, lamenting the entire time that AI was supposed to reduce their work, not increase it. AI was supposed to take things off their to do lists and not add more items on it.
When youโre copy pasting in and out of ChatGPT, you are the middleware. You are the software, in human form, connecting your systems together.
โฆ And that doesnโt make the most of your time, does it? In fact, it can feel a lot like drudgery, constantly copying and pasting.
Shouldnโt a machine be able to do that?
Well, yes. And thatโs exactly what tools like n8n are all about. They help you build the necessary infrastructure around a tool like ChatGPT or other generative AI systems so that youโre not copy pasting any more. They connect your AI to other systems, and can connect other systems to each other.
In fact, Iโd say the majority of use cases for a tool like n8n are non-AI related. For example, a simple workflow might be to connect to your GMail inbox and download all the attachments from your emails to a folder on your laptop. Thereโs no AI involved, but you could see how that could be useful.
That’s why n8n is so hot right now. It’s a fast way to build the rest of the car for the AI engine.
Part 3: How do you get started with n8n?
Getting started with n8n requires a straightforward choice: you self-host it inside your company/your computer, or you subscribe to their paid cloud service. How you make that decision is based on three factors:
- Privacy
- Cost
- Skill
Privacy: if youโre going to be working with sensitive data, data that you wouldnโt want a third party to see, self-hosting is the obvious choice.
Cost: n8nโs hosted options start at $20 a month for 2500 executions a month. Thatโs more than enough for one person messing around with things, but for a team, you could burn through that fairly quickly. And that permits you 5 active production workflows. The self-hosted version is limited only by the computer running it; a self-hosted server could handle thousands of flows and executions if the underlying machine is beefy enough.
Skill: hereโs the make or break. To deploy n8n locally on a computer, you need to have some prerequisites installed, such as node.js, npm, and npx, all parts of the node.js ecosystem. Theyโre all free, but most folks arenโt willing or able to get them all installed and configured because you spend a decent amount of time in the command line. If youโre willing to learn those IT skills (and itโs really just installing software without a point and click interface) then you can load and run n8n yourself. If youโre not willing to do that, or you have a scenario where you want to self-host for a team (which is a more complicated setup), then going with the paid hosting makes more sense.
My suggested setup for the average company that does have IT resources is to self-host. n8n by itself doesnโt require a huge amount of bandwidth or storage. At its core, itโs basically a web server and a scheduler – all its power comes from the systems you connect it to.
My suggested setup for the average individual with no IT resources and no technical skills is to pay for the cloud hosted version, as long as you donโt have privacy issues with sending data to a third party.
My suggested setup for the hardcore nerds, if you havenโt already installed it, is just to run it through npx. Run npx n8n@latest and youโll get the beta server up and running immediately.
Part 4: Setting up your first AI workflow
Now that weโve got access to n8n, letโs start building our first workflow automation. The first thing we do isโฆ not leap into the software itself. As Katie Robbert often says, starting with the technology is the recipe for disaster. Instead, take a look at the tasks youโre doing today and see which one is so repetitive, so boring, so mindless that you desperately wish a computer could do it.
This is doubly true if itโs a task youโre doing in a tool like ChatGPT. Maybe youโre having it clean up transcripts or something equally mundane, and youโre tired of copying and pasting. Using Katieโs Trust Insights 5P Framework, you start by cataloging your purpose and establishing your performance outcomes – the measures of success.
From there, you document the process that you currently use. Hereโs where it gets tricky – many of us, once weโve learned a process, forget its component pieces. We do them automatically, mindlessly, and the tasks all blur together. When weโre building workflow automation, we have to consciously remember all the little pieces that we take for granted.
- Where is the file on our computer?
- What format is it in?
- How do we upload it to our AI tool?
- Whatโs our prompt?
- What do we do with the output after AI processes it?
For example, with my weekly videos, Iโll take the transcript, load it into Google Gemini and generate a cleaned transcript and a YouTube description and YouTube tags. That simple-sounding task is composed of many subtasks, multiple prompts, and a logical sequence. I canโt make tags before I make the transcript, so thinking through the order in which we do things matters.
A workflow automation, in many ways, is like a recipe. You have ingredients – your data. You have appliances and tools – the nodes that contain methods like reading/writing files, accessing AI, etc. And you have steps that you have to follow in order.
In the video version of this newsletter, you can see me build this exact workflow, step by step, from loading the files to creating the outputs.
Part 5: Wrapping up
Workflow automation software is the next obvious evolution of a task you currently do manually. It’s the middle rung on the ladder to building AI agents, which is why learning and applying it is so important. You can’t and shouldn’t skip straight to building an AI agent without first proving that the process works in an automation – and you can’t leap straight into an automation without knowing the components work manually.
That’s why things like the 5P Framework are so essential. You prove out the concept first, set the purpose and the performance, understand who’s doing what, build out a working process manually, and then you introduce automation and eventually agentic solutions. You must build on a solid foundation of proven practices if you want to avoid endless cycles of re-work.
Take a look at what you’re doing today manually, where you are the middleware copying and pasting or manually moving data around. Those will be the ideal candidates for replacnig with automation, whether or not AI is involved. Once you’ve optimized with a system like n8n, you’ll have the bandwidth you need to start innovating new things with it.
