I Built the Ultimate Browser Agent with No Code (n8n + Airtop)

This AI agent can use a computer just like a human would. As you can see, if we take a look at its browser tools, it can start up a browser, it can click, type, query, load windows, and also end those sessions. So the whole point of this agent is to take web actions with completely natural language. Let's hop into a quick demo so I can show you guys what I mean by that, and then we'll break down how this agent works. So what I'm going to do here is ask this agent to find posts on X about Google V03. So I wanted to move over our agent because what it's going to do real quick is it's going to use its start browser tool to spin up a browser in AirTop. And when it does that, it's going to give us a link in our Slack where we can actually click onto that and we can watch the agent move around in a browser. So it's going to be really cool. So now that that browser has started, we got the link and it's going to load up that session. And then we're going to be able to watch the agent actually do things. So right here you can see that it's using its type tool. So it's probably going to move its mouse all the way up here, click on the search bar, and then type in Google VO3. And then it will hit enter so we can search for Google VO3. As you can see, there goes the mouse. We're gonna click onto it. It's typing Google VO3, and bam, now we are searching X. And if you guys will notice, I'm actually logged in down here in the bottom left. You can tell I'm logged into one of my Twitter accounts. So that means that even if you need to be on a site where you have authentication, you can still automate that with AirTop. And already the browser is being ended right now because we already got our results back. Okay, so let's see what our agent comes up with after it was able to search X. So here's what the agent came up with. Based on search results from X, here's what I found about Google V03. Found latest features. V03 now includes native audio generation capabilities. We found availability and reception. It's released in 73 countries through the Gemini app. And finally, we found technical notes. It builds upon previous V02 capabilities. All right, so hopefully that gives you guys a taste of what a browser agent can do. We're going to break down how this build works. I know it may seem a little complicated, but trust me, It's really easy. All we have to do is use natural language. So let's break it down. But before we do that, real quick, if you want to download this template for free so you can follow along with the rest of the video, all you have to do is join my free school community. The link for that is down in the description. You will have to come in here, search for the title of this video, or you can click on YouTube Resources and find the post associated with this video. Once you click on that post, you'll see a JSON file right here to download, which once you download it, you can import that into NN. And you'll have this exact template right here. And then all you have to do is plug in a few credentials and you'll be good to go. All right, so let me explain how this works at a high level. We have an AI agent that has the ability to start up a browser. Once it starts up that browser, it can then click in it, type in it, look at it, load different windows, and then it has to end the session at the end. So the way that it's actually able to spin up these browsers is through something called AirTop, which are these nodes right here. And AirTop lets you automate the web with just your words. You can go ahead and sign up for free using the link in the description, and then you can also get 50% off for 3 months using code NateHalfOff, which will also be in the description. And the cool thing about AirTop is if you click on automations and you go down here to NNN, there are so many AirTop templates already out there for doing things like commenting on X posts, building a list of profiles, extracting information from LinkedIn profiles. There's so many different use cases for browser automation. Anyways, let's start to break down this workflow a little bit. First thing I'm going to do is just click into the system prompt and show you guys how simple this is. So the overview is that you are a smart advanced web agent and you have tools that let you control a remote web browser. Your primary goal is to fulfill the human's request, and you're able to do that by using the different tools that you have. So then the next thing I did was I gave it its tools. So it has the ability to start a browser, which I said always begin with this tool. It returns a session ID and a window ID, which are required for the other tools because other tools like click or type have to know, okay, which actual browser am I clicking or typing in. You also have the tool to load a URL, which loads a website in the browser window. You have a tool called query, which basically lets you scan the browser and you can extract information like where's the search bar or what's the menu options or, you know, any information that you need to retrieve like our X-posts. You have a tool called click, which you use to click on certain elements like buttons. You have the tool called Type, which lets you type into visible input fields like search bars, and it also automatically hits Enter after you're done typing. You have a tool to end the session, which must be used every single time before you respond to the human, because we want to turn off that browser session in AirTop. And then we gave it access to the Think tool, which lets it think and reflect on what it's done and what it still needs to do, which I found be really helpful for browser automation. And then I gave it a few tips that are important, like always think step by step, use the query whenever you're unsure of what's on the screen. and you'll never need to log in. All right, so let's just start off by looking at that Start Browser tool. So you guys will notice that this is not an AirTop node. This is an N8N workflow tool that we configured ourselves. So I'm just gonna scroll over, over here, and this is the actual Start Browser tool. So let me just drag this over here so we're looking at everything in one clean screen. So when the browser agent calls this tool to start a browser, it actually goes through this flow to start that browser. So what I'm gonna do real quick is pull up the execution from that live demo we just did, and we'll see how it started up the browser. So here's that data right here. It passed over twitter.com so we could go to X and scrape it, and then also passed over my profile name, which I set up in AirTop. I'll show you guys that later, but that's how you can access something like X or Instagram or whatever you want to go through that requires a login, because you can set up that login once in AirTop, and then your agent in N8N can access that and do whatever you want. Anyways, from there it's going to do two main things, which is set up a session and set up a window. And once we've done that, we get back both a session ID and a window ID. And right now I'm in my AirTop dashboard. If I click on browser sessions, you can see all the previous sessions that I've had with different remote browsers. What we also get is a live URL. So this live view URL lets us click on it and we can go watch the browser agent actually interact with stuff. So that's what you guys saw me click on earlier in Slack. So all I'm doing here is I'm sending myself that URL. And then the last thing we have to do is we have to give back the session and window ID to the main agent. So we do that with the set node where we basically say, okay, here's a session ID and here's a window ID. All right, so while editing this video, I just realized there was something that I wanted to touch on in a little bit more detail, which is basically like what is going on in the transfer of data between this tool to start the browser And then down here, this actual workflow that starts the browser and sends us back that session and window ID. So what this tool does is it lets us call on a different NNN workflow as a tool. And typically we would have something like this in a separate workflow that we would call on, and we would do that by choosing from list. And then we could just choose a workflow that we had done from list. Like let's say I had a tool right here to grab profiles. I could hook it up and then now data's being sent to that tool. So if you want to call on the tool that lives in the same workflow like we see here, all you have to do is you have to do it by ID. So in your URL up here, I think it's cut off for you guys, it'll be workflow slash and then a bunch of like capital letters, lowercase letters, and numbers. You will basically just copy that and then you'll come back into this tool, change this to by ID, and then you'll basically just paste that right in there. And then you have the workflow inputs and profile name to actually map. So just wanted to clear that up. Hopefully it's not too confusing. You have the option to keep it in this workflow, or you can move it into a separate workflow and call it from a list. But there will also be a setup guide kind of right over here that explains everything you need to do to connect yourself to this agent when you download the template. So let's get back to the video. Okay, cool. So that's the Start Browser tool. I'm gonna go back into the execution, which was our actual browser actions, and we're back. So like I said, browser agent calls this tool. Starts the browser, we get session ID and window ID, and now the agent's able to figure out what do I have to do next. So in this example, what it did next was it typed. So it called its type tool, and what happens here is really, really simple. First of all, it sends over session ID and window ID, which are right up here, and this just says, okay, browser agent, this is the session and window that you're going to actually type in. And then we have to tell it basically what are you going to type and where do you type. So as you can see right here, the element description is the search box that says search X, and the text is Google VO3. And that's exactly what we saw it do in that little live window. And then this type tool responds to the main agent and says, type operation completed. And then the agent realized, okay, now that we've made that search, I have to query the page to see what those results look like. So I called on this query tool. We do 3 things. Once again, we're sending over session ID, window ID, and then we're sending over a prompt, which is what do you actually extract from this page? Page. And the prompt was, what are the search results showing about Google VO3? Please summarize the most relevant points and information. And then on the right-hand side, this tool responds back to the main agent and says, the search results for Google VO3 highlight several key points, and then it lists off all those points. And then finally, before it actually responds to the human with those answers, it just has to end the session. And that's really simple because all we have to send over is a session ID. All right, so that was one quick example. Let's just go through another example and we can see if it uses any different tools and how that all works. All right, so this time we're saying, find me good deals on laptops from Best Buy. So what I'm gonna do once again is just kind of move this guy over so we can pull up our Slack so we can watch it happen live again. Starting up that browser, which is actually calling that workflow below us that we just looked at. And what it's gonna do is send us over that live link so that we can watch the agent take action. Okay, so our browser session's been started. We got a link, and now we're gonna load that up. We can see the agent right now is typing, so we'll see if it's typing for laptops or whatever it does. It basically has full autonomy to use whatever tool it needs to do to get the job done. Okay, so we can see the mouse just clicked on the search bar. It typed in laptop deals, and then it went ahead and hit enter. Okay, so the live view's a little bit behind, but it loaded up a new page, and now we can see the agent's using its click tool. So we'll have to take a look and see what it actually did. And it's actually using the load URL tool. So we've got a couple new tools to look at. So it looks like it pulled up a page of 858 laptops and now it's querying it once again. Okay, there we go. So it's ending the session. The browser has been disconnected. So let's close out and let's come over here and see what the agent came up with. All right, there we go. So I found several good laptop deals currently available at Best Buy. Here are the most notable ones. So we've got a Microsoft Surface laptop, latest model, which is $200 off. It's highly rated. It has 16 gigs of memory, 512 gigs of storage, blah, blah, blah. We have a Samsung Galaxy that is $142 off. And we also have a Lenovo Yoga, which is starting open box $270. So cool. Now what we're gonna do is I wanna look through the actual agent logs so that we can see what it did and why. So I'm just gonna click on the agent. I'm going to click on logs and let's take a look. So the first thing that it did was obviously it started up the browser. Then it called its type tool and it says to type for laptop deals. So that's exactly what we saw happen. Then it used its query tool and the prompt was, what are some of the best laptop deals currently shown? Please list the prices. And then the query tool responded and said, unable to satisfy object. The webpage content provided does not contain any specific information about laptop deals, prices, or descriptions. So then what it did is it decided to click and it decided to click on the link that says laptops or laptop deals. So super cool. So it basically clicked on that link and it loaded up this new URL. As you can see, this one right here about laptops. And then we go to the query tool once again to ask that same prompt, which, what are notable deals? And then once we actually get that answer back right here from that query tool, it knows to go ahead and end the session. So let's take a quick look at what happens in the click and the load URL tool since we haven't looked at those yet. Real quick off the bat, there is a native integration click tool right here for Airtop. But what happened when I was using that is I kept getting these like timeouts. So I was able to use the HTTP requests to have more control over it, and now I don't run into that issue with timeouts. So in the click one, we're sending over session ID, window ID, and then we're just saying what to click on. So right here it says link that says laptops or laptop deals. Oh, okay, and one thing I actually missed is that it didn't work. So that's why it had to go load a URL, because right here we can see that it actually failed to click, and probably because there wasn't actually a button that that said one of these things. So then it said, okay, that didn't work. I'm gonna just go load my own URL. And we loaded up this URL, bestbuy.com/site/laptop/computers, blah, blah, blah. And then because that worked, the agent was able to query through it. And then of course, before it responded to us, it went ahead and ended that session. Okay, so what's special about browser automation is that it basically spins up a remote browser. So it looks a lot more like a human's actually controlling stuff because it moves the mouse and it does all this stuff. And so what I showed you guys with the demo with X is that I was already logged into my account. So what you can do is when you come into AirTop, you click on profiles, and then in an actual profile, which I just created, when you connect, it basically will let you enter in a website and you can log in with your credentials and it saves them to that profile. So if you came in here and saved your credentials for Amazon, X, Instagram, LinkedIn, whatever you wanted to, you could then connect and do things in a browser through an AirTop agent. I would just strongly encourage you though to look into the policies for the different websites and providers because some of them are really strict on even browser automation bots. So just be careful with that. But once you basically create all of those different credentials, this is the name of your profile, and that's what I'm passing over when I start up the browser. So in here, when you see I'm starting up the browser and I'm passing over a URL, which is what URL to load in, and also a profile name, which in this case was Nate Hurk because that's the one that I made right over here. But you don't necessarily need a profile name. You only need to provide this profile name if you want to access a site that has credentials or has to log in. So just as one final example, just to show you guys, I'm going to completely remove the profile and it's— there's going to be nothing being passed over, and I'll show you that we're still able to browser automate. So like this previous example right here with Best Buy, we didn't have to log in to do so. But just to show you guys that I'm not lying, right here we're just going to say find a Yeti water bottle on Google. It's going to go ahead and start a browser with no profile, no credentials saved. The browser just got started, so let's load up that window. We can see that it's going to type, so it's going to type in this Google search bar, Yeti water bottle. There we go, Yeti water bottle. Hit search. And now it's going to use its query tool to scan these results. There we go. It's ending the session because we found everything we needed to. And then we will just basically see that it worked. And keep in mind, I'm not passing over any sort of profile name, so you only need to do that if you're accessing a site where you actually need to log in. Okay, so here's our results. They range from sizes 18 oz to 64 oz, prices ranging from $20 to $65. Here are some places you can get them, blah blah blah. All right, so some final things to think about real quick. The reason I'm using a Click HTTPS rather than the native AirTop node for the Click tool, I was running into some issues where it was timing out. So the Click tool does work, but for certain requests it was just timing out on me. So not sure if you guys will have a similar experience or not, but that's why I switched it out. I'm sure you guys are probably wondering about like different use cases for this because I know it seems just kind of fun and flashy, but there definitely are good use cases for this. Like I said, I'd encourage you to go to Airtop and check out the N8N templates. There's a ton of cool stuff like ICP scoring, LinkedIn person ICP scoring, monitoring competitor price changes, monitoring job changes, all that kind of stuff. And remember, you can use code NateHalfOff for 50% off 3 months. Okay. And finally, when you get in here and you need to set this up for yourself, what do you actually do? First of all, you'll have to connect a chat model. So I'm using OpenRouter and I'm using Claude 3.5 Sonnet. I tested out GPT-4.1. I tested out some other ones. I definitely found that 3.5 Sonnet or the higher power Claude models worked the best. So that's why I went with that here. I also gave it access to a think tool, which is pretty cool because sometimes it would get stuck and it would come here and think about it. Obviously it's better when it doesn't have to use it, but on some more complex things it may have to use a think tool. So it's good to have that there. And then of course you'll have to come in there and plug in your own AirTop API key, which is super simple because of the native node. You'd come in here, create new credential, and just plug in an API key. You could get that from AirTop if you go to your dashboard and you go to API keys right here, and all you'd have to do is click on create new key and copy and paste it in. And finally, I'm sure you guys are wondering a little bit about the plans. So you can start for free and get 5,000 credits, which will last you quite a while. If I go to my billing, you can see that I've done about 2 hours of automation with this, just testing out, and I just finally passed over the 5,000 free limit. So, um, if you go ahead in here and you can get 30,000 credits for $15, if you use my code, you can get 100,000 credits for only $45 if you use my code. And the other thing here is you have different amounts of simultaneous browsers. So, you know how I said you start up a session and then the agent uses its tools and then it ends the session? How that works is back here you have browser sessions. And this keeps track of all of the different sessions you have active. So if you're on the free plan, you can only do one active at a time. If you're on the starter plan, you can have three running at a time, but that's it. And that's why you have to make sure at the end that you actually terminate them using this tool right here, end session. Otherwise they'll just keep being active forever. Well, I'm sure they'll time out eventually, but they'll stay active for a while. And so really you should get in here and you should customize the prompt a little bit and play with the different tools to fit your use case. But this is a really good skeleton and a really good place to get you started. Rather than starting from scratch. And you can download this entire template for free by joining my FreeSchool community. Link for that is down in the description. When you download that, there'll be a setup guide somewhere right over here that will basically tell you what you need to plug in and all of the different API keys that you need to connect. You'll also need to, of course, connect something like Slack if you wanna grab those live URLs. But anyways, that's gonna do it for this video. If you guys enjoyed this style video, then definitely check out my paid community. The link for that is down in the description as well. It's a great community filled with like-minded people building with n8n every day. Sharing their challenges, sharing their wins, and it's a really cool place to be. We've got two full courses, one called Agent Zero on the foundations of AI automation, and then a course called 10 Hours to 10 Seconds where you learn how to identify, design, and build time-saving automations. So I'd love to see you guys in those calls or in the community. But if you enjoyed the video and you learned something new, please give it a like. Definitely helps me out a ton, and I'll see you guys in the next one. Thanks everyone.
