Host: Greg Isenberg
Episode: Is Gemini 3 a 10x Designer? I Wanted Proof.
Date: November 21, 2025
Episode Overview
In this episode, Greg Isenberg dives deep into the creative and practical capabilities of Google's Gemini 3.0 within Google AI Studio. The challenge: put Gemini 3.0 to the test as a designer—specifically, to see if it can achieve "10x designer" quality in three areas:
- Personal website design
- SaaS app dashboard design
- Mobile app design
Greg provides live feedback, iteratively prompts Gemini, and rates its designs on a scale of 1 to 10, all while offering his candid, energetic commentary on AI’s impact on the design process and the startup landscape.
Key Discussion Points & Insights
1. Setting Up the Test: What Can Gemini 3.0 Really Do?
[00:00] – [03:30]
-
Greg outlines his plan: test Gemini 3.0 across three design challenges.
-
Emphasizes his limited prior experience:
“The only exposure I had to using Gemini 3.0 and Google AI Studio was…in the episode I did the other day with Logan Kilpatrick from the DeepMind team. It did a pretty good job at it, actually. …I wanted to go deeper.” (00:28)
-
He notes Google’s rapid evolution:
“…Think about where they were 12, 18 months ago. They were literally building Google Bard. …Now their cursor competitor is called Ultra Gravity. Way cooler, right?” (02:15)
2. Personal Website Redesign: Gemini’s First Test
[03:30] – [15:00]
Initial Prompt & Setup
- Greg uploads a screenshot of his current website, prompts Gemini for a "Microsoft XP" aesthetic, asking for more color, freshness, and a full experience without much detail.
- Observes Gemini’s process in Google AI Studio:
“You can see here it's actually creating the metadata JSON, the index HTML…it's using tailwind CSS React…” (04:40)
Evaluation of Output
-
Gemini delivers a Windows XP-style website, incorporating site copy and functional links:
“The notepad is over here where it says, like Greg Eisberg, the Internet is my playground. I kind of love that tagline. It's taken the copy from my website already. …This is crazy.” (07:25)
-
Functionality check: Works surprisingly well on mobile.
-
Greg gives feedback: improve the “application” icons to look like real Windows/Mac app icons, and adjust the boring white background to match XP’s classic blue-sky/green-hill palette.
Leveraging the Annotation Feature
-
Greg tries Gemini’s annotation tool to visually prompt a background change:
“Yes. So Logan was showing me this. You can highlight components, sketch new ideas or add precise feedback right where it matters. …pass your visual prompts to Gemini and watch your app update live.” (10:38)
-
After some iteration:
“It broke the icons. But …having the background looks nicer. …It didn't take my feedback around creating the mountain. …Overall I don't know about you, but I'm pretty damn impressed. This exceeded my expectations on this personal website. Nine on ten for me.” (14:35)
Memorable Quote:
“Good design is viral. Good design is something that people talk about. Good design adds trust. So that's why, you know, you should want good design.” (13:16)
Rating:
- 9/10: “This exceeded my expectations…” (14:35)
3. Designing a SaaS App Dashboard
[15:00] – [23:00]
Prompting With References
- Greg uses a Dribbble dashboard as a visual reference, describes wanting a SaaS analytics/AI app for restaurants with clean, modern, “real feeling” buttons.
- Adds a second reference from Teenage Engineering for tactile inspiration:
“I also included a photo of a Teenage Engineering product that's physical that I imagine the buttons could be, you know, used on the SaaS app.” (17:55)
Gemini’s Output
-
Gemini delivers:
“Here we have it. So that looks really nice. That looks really nice. The buttons look really nice. They've got that teenage engineering vibe. …That is cool.” (20:57)
-
Greg appreciates the visuals and functionality hints:
“They’ve created this AI analyst Chef os. Does this thing work? …Like this is something you might be able to like sell to a restaurant. I think this looks super, super, super good.” (21:32)
-
Small usability critiques, but overall quite impressed.
Rating:
- 8.5/10: “This is one prompt…8.5 on 10.” (22:13)
4. Designing a Mobile App: The "Gains Fitness" Prototype
[23:00] – [28:45]
Creating a Gamified Fitness App
- Greg references the "Brainrot" app (helps break social media addiction), asks Gemini to design a fitness app in that style.
- Specific prompt: Use mascot, gamification, warm colors; ensure iOS-native appearance.
Output & Assessment
-
Gemini generates “Gains Fitness”:
“It features a mascot that reacts to your workout habits. …It's got the streak. It's got the goal Maintenance mode. …Imagine, like, it integrates with Apple Health.” (27:24)
-
Greg pokes at limited prototype interactivity, but likes the design polish:
“…From a one prompt, I'm going to give this an 8.3 on 10.” (28:10)
Context & Tools
- Mentions competitors (Roark, Vibe code app, Create Anything), points mobile development will be covered more in future episodes.
Rating:
- 8.3/10: “From a one prompt, I'm going to give this an 8.3 on 10.” (28:10)
Notable Quotes & Memorable Moments
-
On AI-Driven Product Creation:
“It really is like if you have good ideas…you can stand out, right? …A personal website, everyone has …But …if you can stand out, maybe that gets you the…job you wanted. …Good design is viral.” (12:32)
-
On Gemini’s Progress:
“We’ve exited this era where Vibe coding produced not the most beautiful websites, not the most beautiful apps. …With the right reference images, the right prompts, you can design something beautiful.” (30:15)
-
On the Future of AI Tools:
“We are getting scared. It’s getting scary good. …If you just keep prompting it, I think you can get to places where you have an extremely well designed app without any designers. You are the designer right now…” (29:46)
