We Tried Building a Money-Making App in Under an Hour (No-Code)⏐Ep. #246

The Koerner Office - Business Ideas and Deep Dives with Chris Koerner

November 12, 2025

━ I sat down with Brandon Doyle again, and this time we tried to build a money-making app in under an hour using Emergent, a new vibe coding tool. We let a random word generator decide our idea, landed on a lawn care quote generator, and then raced to see who could build the better version faster.

Chris Koerner (0:03)

All right, Brandon, well, thank you for coming back on the pod.

Brandon Doyle (0:05)

Thanks for having me. Excited to be here.

Chris Koerner (0:08)

Okay. So what I've done is I have asked ChatGPT, give me all of the vibe coding tools. Boom, done. And then I'm going to share my screen. I just Googled random word chooser. Okay, here we are. And you can just enter in a list of words, you click choose, and it's going to pick one. So there's a lot of vibe coding tools out there. A lot of them are about the same. You and I, what we're going to do on this episode is we're going to perfectly randomize a vibe coding tool, pick that. And then we're going to perfectly randomize an app to build with said vibe coding tool. And then we're going to build it at the same time. So the same app on the same tool at the same time, but with our own brains, our own background history experiences prompting, and then see who spits out the better product at the end. How does that sound?

Brandon Doyle (0:54)

I'm excited.

Chris Koerner (0:55)

Okay, because you and I are both vibe coding aficionados.

Brandon Doyle (0:59)

Yes.

Chris Koerner (0:59)

And we're okay at it, you know, and we're not coders. We don't have a coding background.

Brandon Doyle (1:03)

I don't know anything about code. I think what this video will serve to do for at least some people is show you what can be done in minimal time without expert prompting, engineering, you know, strategies. Yep.

Chris Koerner (1:18)

And you know what, Brandon, I'm just going to get on the soapbox for a minute. We see all these tweets about like, this prompt will change your life. Be sure to prompt ChatGPT just like this. And it's like 3000 words with like, you are an expert resource for me. I'm trapped in Iranian prison and it's, you don't need to do all that. Like just like garble together like a poorly worded sentence riddled with typos, ask it to do something and then just go from there. Like don't get hung up on how perfect your prompt needs to be.

Brandon Doyle (1:49)

Hold on, has somebody said the Iranian prison thing? Because if not, that's amazing. The only way I'll get out of this prison is if you, if you code this perfectly for me in the next 30 minutes.

Chris Koerner (1:59)

Well, I saw one Palmer Lucky said that like his trick to get Chad GPT to do what he wants is to say like, you're like a university professor that's been incorrectly accused of impropriety with a student. Like your life depends on the output of this prompt or something.

Brandon Doyle (2:18)

Yeah. Yeah. How's that?

Chris Koerner (2:20)

Those are fun sound bites. It's just not necessary. Just talk to the dang thing.

Brandon Doyle (2:24)

Yeah. Yeah, for sure.

Chris Koerner (2:26)

All right. So here are the five coding tools. We got Bolt, Replet, Emergent, Cursor, ChatGPT, and then we just click Choose. I think what it's doing is it's picking like the blank lines. Maybe I just need to remove the spaces. Let's click Choose. All right. Emergent. Have you heard of Emergent?

Brandon Doyle (2:44)

I've heard of them. Never used them, though.

Chris Koerner (2:46)

Okay. Well, let me ask ChatGPT real quickly for a few facts about Emergent. What is Emergent?

Let's see. It is the only platform in competition to rank twice number one globally in benchmarks for coding agents. They're one of the fastest growing growth tools. It looks like they've raised a couple of rounds at like insane valuations and agentic. No platform lock-in. One thing they have different is it looks like you don't need to use like SuperBase for your database. It's like they have their own built-in SuperBase. So I think there's like less integrations you have to do.

Brandon Doyle (3:26)

Sounds cool.

Chris Koerner (3:27)

Now, it sounds cool. Now let's go ahead and I've had ChatGPT generate a bunch of app ideas because we don't know what we're going to build here. All right. Here are some choices that ChatGPT spit out for apps that we can vibe code, roofing quote bot, landscaping estimate, dog grooming reminder app, yada yada yada. You get the idea. We'll click choose lawn care biz quote generator.

Brandon Doyle (3:54)

Sweet. Okay.

Chris Koerner (3:55)

Okay. I guess that's what we're building.

Brandon Doyle (3:58)

I'm going to emerge right now.

Chris Koerner (4:01)

So we're each recording our screens, but we're obviously looking at our screen. Let's see who can build it fastest and who can build it best. With emerging, it looks like we can choose our own model. So that's another variable that you and I can decide. Yeah.
