17 Oct 2025

Transcription

Chapter 1: What is the main topic discussed in this episode?

0.031 - 17.753 Greg Isenberg

Alex, by the end of this episode, what are we going to learn?

0

Chapter 2: How can I find app ideas using Idea Browser?

18.087 - 30.077 Greg Isenberg

We're going to be using two really awesome tools. We're going to be using Idea Browser to come up with a really amazing business idea. And then we're going to be using OpenAI's Codex to build out that idea.

0

30.719 - 31.962 Alex Finn

Okay, let's get started.

0

Chapter 3: What role does ChatGPT play in developing app concepts?

39.67 - 51.946 Alex Finn

I must confess that I built Idea Browser for myself. So I am a co-founder in Idea Browser. But I think that if it's valuable for me, it's going to be valuable for other people. So let's get to it.

0

52.787 - 68.007 Greg Isenberg

And I must confess, I have absolutely no affiliation with Idea Browser whatsoever. I just find it awesome to find ideas. So let's do it. All right. I am going to share my screen. First of all, props, Greg, on Idea Browser. Awesome, awesome platform for me.

0

69.337 - 73.643 Alex Finn

Well, the context there, by the way, is that I run a holding company.

0

Chapter 4: What are the capabilities of OpenAI's Codex?

73.663 - 91.446 Alex Finn

So we're constantly incubating, investing, and acquiring businesses. So we need ideas. Ideas are the lifeblood of our business. So the whole idea is if you can scrape Facebook groups, subreddits, get data, and create validated ideas, then you have an unfair advantage.

0

91.831 - 99.084 Greg Isenberg

Yeah, and I talk to a lot of vibe coders and new people to AI every single day, and building has never been easier.

0

Chapter 5: How do I build a Minimum Viable Product (MVP) using AI agents?

99.144 - 116.674 Greg Isenberg

The challenge is the ideas. People can't come up with good ideas, and so this is a fantastic way to find them so you can find things to build out. I personally use this kind of as like a boxing gym, in a way, idea browser, where it's like, okay, I'm going to go into this. I'm going to find ideas. I'm going to build them out.

0

116.654 - 131.253 Greg Isenberg

Not always necessarily will they be million dollar businesses, but at least I'll get that practice of going from my idea to building. And so what I'll do is kind of walk you through how I use it and we'll choose an idea and we'll start building it out. But where I like to start off is market insights.

0

131.273 - 151.533 Greg Isenberg

What's cool about market insights is it pulls from a lot of the big social media networks, right? Reddit, Facebook, and you can see what people are talking about. See their pain points, see where there might be solutions and maybe come up with ideas from these. So I don't know too much about psychedelic assisted therapy, but I know a little bit about email deliverability.

0

151.573 - 172.463 Greg Isenberg

And so I'll come in here. I'll see what pain points people are having with email deliverability. Sudden drops in deliverability. If you have a newsletter like I do, you know this is something you run into all the time. Fear of Google outlook policy changes. You can really find some cool, interesting pain points to solve from these marketing insights.

0

173.236 - 195.057 Greg Isenberg

They give you some solution gaps, places where there are no solutions at the moment, segments that are underserved. A lot of really cool ways you can pull ideas from here. But where I seem to personally find the most ideas to build out is I like to go to trends. This is just like... purpose built, ready served on a platter, things you can build out.

195.077 - 196.74 Greg Isenberg

Like I don't even have to think too hard, right?

Chapter 6: What marketing strategies can I use to launch my app?

196.8 - 216.135 Greg Isenberg

Like website design for small businesses, wellness app. This is a cool one. So this is, this is one I've been thinking about and it looks like it is having a lot of volume and growth at the moment. And so what I'll do is I'll look for a trend that I myself have interest in because the best products to build out are things you have interest in. I'll click in

0

217.55 - 221.738 Greg Isenberg

And what this is going to do is give me more information on this trend.

0

Chapter 7: What steps should I take to gather beta testers for my app?

222.158 - 239.49 Greg Isenberg

So I can actually pull up the wellness app here. It'll tell me a little bit about how many monthly searches this app or this trend is getting. Tell me about what people are searching for with this trend. A wellness app refers to a digital platform designed to support individuals in achieving and maintaining their health and well-being goals.

0

239.47 - 259.977 Greg Isenberg

and gives me a little bit info on how many people are searching for this. And as you can see, a lot of people searching, not a ton of competition. So this for me, when I'm coming into Idea Browser and I'm looking for ideas to build out and practice my building skills, this is kind of exactly what I'm looking for. Things that are having good growth,

0

259.957 - 276.482 Greg Isenberg

things with not a lot of competition and things where I myself am interested. I'm interested in wellness. I work out. I try to eat relatively healthy, not including chocolate. And so this is something I, for me is a really good candidate for, to build out.

0

278.165 - 291.955 Alex Finn

It's funny. Cause like when you put it like that, find something that is in a growing industry with low competition that you personally understand and love. Obviously, your chances of success is going to be highest there.

0

292.964 - 304.256 Greg Isenberg

Well, the chances of success honestly are 100%. The reason being is like at the very least, even if no one buys the product at all, you've built a product for yourself, right?

Chapter 8: How can I leverage AI tools for effective product development?

304.276 - 323.818 Greg Isenberg

That'll improve your own life. And like for me, my business creator buddy, I built it because I wanted to build an AI that analyzes my posts. At the very least, if no one bought it, I would have a product for myself to improve my own content. And so that's why it's always a win if you build things you're interested in. So here's my workflow. This is what I do. You know, I got into trends.

0

323.838 - 350.535 Greg Isenberg

I found a trend I really like. I have a prompt I built called the Idea Browser prompt. Purpose built for Idea Browser. I'll go, I'll take this trend. I'll copy it. I'll go into chat GPT, which for me at the moment, GPT-5 is the most powerful model there is. Sonnet 4.5, incredible for coding, the best for coding, but straight up for chatting, ideating. I'm still a GPT-5 guy.

0

351.736 - 375.823 Greg Isenberg

And so what I'll do is I will take my prompt, and we can put this in the description down below. But basically, the prompt is this. I'm giving you a link to a business idea from Idea Browser. Your job is to act as a professional app builder and creative strategist. Read the page and then generate three high-quality, unique app ideas inspired by that idea. For each app idea, include the name,

0

376.259 - 399.82 Greg Isenberg

a concept summary, core features, why it works, and why it would succeed in today's market. Keep it practical and make it easy for a solo founder to build out. So I have that prompt. I'll take our trend we found. I'll put it in here. So here's the idea. Paste it in. And what this is going to do is have chat GPT

0

400.795 - 426.87 Greg Isenberg

Go into that website, see what that trend is all about, and then give us a few ideas for what we can build out in our next stage, which will be going into Codex and actually building out that idea. So we have a few different ideas here. We have Mood Mosaic, which is an expressive mood journaling and creative wellness app for people who want a more visual, playful way to track emotional health.

427.34 - 450.588 Greg Isenberg

Rather than writing pages of text, users paint their mood via simple sketches, colors, stickers, and stamps. Maybe. A little out there. WellSyncBuddy. WellSyncBuddy is a wellness, accountability, and habit pairing app that helps pairs, small groups, synchronize and support each other's wellness routines. And it's for people who thrive on social accountability.

451.489 - 475.224 Greg Isenberg

That's actually a multiplayer social network wellness app. It's not a bad idea. And then we have Biorhythm Coach. Biorhythm Coach is a personalized micro wellness app built around users' individual daily biorhythms. It nudges users to schedule task breaks and wellness micro practices like stretching, breathing, and light exposure in alignment with their energy peaks and troughs.

476.005 - 498.726 Greg Isenberg

That one's pretty cool. I think... I don't think any of these are bullseye for what I want to build, but what we can do from here is we can take certain ideas and combine them into one, right? Like some of these are a little abstract, like mood mosaic. I don't really want to build like a drawing app. Well sync, building a multiplayer social network is a little tough for one podcast.

498.746 - 535.023 Greg Isenberg

Biorhythm, I kind of like getting daily habits based on your goals. So let's do this. I think what we can do is we can say, I like idea number three, but it's a little abstract. Build me a plan for a habit tracker that also builds us wellness routines. So what I really liked in this one was the wellness, micro wellness app.
