get into it, though. So, here's the prompt I'm going to do. I want to build a stock portfolio app. It should allow me to type in a ticker for a stock. And by the way, the prompts down below if you want to follow along with me. Highly recommend it. Then it saves the stock to a watch list, pulls the data about the stock from the Alpha Vantage API, really nice free stock API, displays the chart, and displays other helpful information. It is critical that this is a beautiful app that doesn't look like it's built by AI and has nice animations and transitions so it feels really nice to use. Any other features you think are interesting, please add them. I like to add that so that the I can test the model to see what new ideas it can come up with and how creative it can get. Let's do this. Let's just hit send. Let's get it popping and let's get the model working. It is going to be interesting to see how this cursor inhouse built AI model will perform. I'm going to hit run. I'm going to allow it to create all the folders. This is a fresh new project we're building here. No prior code or anything inside it. We're building it from scratch so we can see how this does. We're going to test this out in the inapp browser that cursor just released as well. I like the sound of this feature. We'll see how that goes. We'll see if we can actually test the browser inside the app. I'm going to run this and I'm going to keep it running. Uh I do like the user interface. Composer and cursor have always had uh some of the best user interfaces. Very clean and easy to read. They also up to this point had one of the strongest uh plan modes as well. We're not using the plan mode for this. We're just letting it run to see how well it does. And once this gets built out, what I'm going to test next is how well can this go with multiple agents. I'm going to spin up a bunch of agents right after it builds out this V1. I'm going to see are they going to conflict with each other? clash? Is it going to crash? We're going to see how managing multiple agents at the same time in cursor is going to go as well because that's kind of the whole point of this cursor 2. 0 is to make it so instead of writing code, managing code, looking at code, you're just a manager of agents. You're just like the CEO of this agent company, the agents are going and working for you. So, we're going to see how that experience is when we run like six or seven different agents at the same time. So, stick around when we see that. But, I'm going to let this run. And build out here and we're going to see what this looks like in just a second. And wow, this is actually fast. Uh I have not really edited this at all. We're probably what, a minute in here, and it's already made,00 lines of code. That is pretty good. That is definitely faster than the other models. I can say that right off the rip. This is probably the fastest coding model. Uh it is coding very fast. That is very impressive. But I will say this, speed means absolutely nothing if the code stinks. So we're going to see if this works. Wow. Oh, just like that, it's telling me to npm run build. Okay, so we're just going to let this rip. This is it. This is working right away. Let's see how this goes. Wow. It is coding so fast that I literally uh cannot even read what it is doing. It is going so fast. That is extremely impressive. I assume it's running npm run build over and over again uh so that it can test what it's doing. Uh I again I can't even tell because it's moving so fast, which I think is a good thing. I think I like that. All right, build succeed. I literally it's moving so fast I can't read anything it's saying. All right, let's see what we got here. How to use start your server with npm rundev. Search for stocks. Click a result to add your watch list. I think we probably need to add the Alpha Vantage API somewhere. Oh, here we go. It's down. Important. The app uses a demo API key here. Place it in Alpha Vantage with your Alpha Vantage API key. Okay, so I'm going to grab that. I'll have a link to the Alpha Vantage API down below if you want to do this with me. Just it's completely free. Just put in your email, you'll get a key. All right, so I put that in. Let's test this out. So I'm going to open up the terminal. I'm going to do npm rundev. That looks like it's running. Okay, let's see if we can do Can we use the inapp browser here? Let's go browser tab. We're going to enter, I assume, local host right here. So, this is just Google Chrome builtin. Let's see how we go here. Okay. Uh, this looks terrible. Let's just see. I'm going to open up in a regular Chrome tab to see if it looks any different. And I'm going to pull it open. Nope. Looks exactly the same. It looks terrible. That's one of the worst looking apps I've ever seen in my life. Uh, I'm going to imagine the styling is not getting applied because there's no way it would by default think this is the way an app should be styled. So, let's go back to the agent here and let's say looks like the styling didn't get applied and I'll send a screenshot. Whenever you get UI issues or anything like that, just screenshot what you see, put it in here. I wonder would we be can we select element toggle? It'd be cool if I could like Oh, take Okay, take full page screenshot. Oh, that's what I was looking for. That's what I wanted. Okay, cool. I like that you can just take a full page screenshot. I like that. Let's hit enter. That's a good feature. Thank you, cursor. That is a good feature. But now, more important than screenshot features is the model actually doing well. So, let's see how it goes here. Let's see if we could fix this UI issue because that is I don't even want to test it. It's so ugly looking. It hurts my eyeballs. Checking why Tailwind isn't applying. review the current. Okay, I'm going to have it review the current CSS setup. We're using Tailwind v4, which requires different syntax. I've seen this a lot with all models to be honest with you. For some reason, they all go for Tailwind 4 and then have no idea how to use it. So, they always have to downgrade to three. For me, Claude Code stopped doing this like a month ago. It was doing this all the time and then it stopped. Codec still does this sometimes for me where it just it doesn't know how to use the newest version of Tailwind and I force it to downgrade. And now we're doing it with Cursor's new agent. So, we'll see if it can figure it out here if we're going to go into a circle here right off the rip. Here's the thing. It is fast. It is the fastest one out of all of them. But if it is running lowquality code or doesn't understand what it's doing, the speed doesn't matter. It just doesn't matter if you do I'd rather have the right thing done slow than the wrong thing done very fast. So, hopefully you can figure this out. It's I've had to run literally 400 different commands right now to fix styling being applied. All right, looks like it is all set. Let's run npm rundev and see if it was able to fix this. I'm just going to open us this up in Oh, there we go. Look at that. That looks good. It fixed it. Okay, so it felt like it was taking a little while to do it, but it actually fixed it. That looks beautiful. Good work. Let's uh let's test it out. Let's uh do Apple hit. Oh, I like that. I uh type in the beginning of the company and it gives me a bunch of suggestions. I've literally never seen any coding model do that for like build that out when I asked them to build this app. Like this is usually one of my first tests is to build like a stock market app. I've never seen them have like this autofill suggestion before. So that is really smart and nice. I hit it. Oo, that is nice. That is really well formatted. I like the UI. It is clean. Let's uh you know, it is nice that it's doing it in this little tiny browser, but I'm going to pull open regular Chrome just so we can see it in like a browser people would use. All right, let's do Tesla. Oh, that comes in. I like the way it like slides in all the stock slide. That's a nice attention to detail here. The charts looking good. Is this real time data? I think it is. I think this is real time data. Gives all the information on the stock. I like that. This is nice. This does look Oh, I could favorite. They add favoring. So, they did add some features. Oo, and then the watch list. The watch list is nice. Okay, so this is good. And it says live data. This is good. Does it still go with the blue and purple color scheme that every other AI on planet Earth goes with for some reason? Yes. the first AI model that makes it so blue and purple aren't the default color scheme for everything. I will be I will use that model forever. Be the first one. That's all I ask. All right, so let's move on to other features. We tested the model a little bit there. It looked good. Listen, it messed up at first, but it recovered and it recovered very nicely. Let's do this. Let's use what this was built for, which was spinning up and managing tons of agents at once. Let's go into it. So, we're going to do a new agent. We're going to keep using the
