Build anything with Google Gemini 3, here's how...

Google just dropped Gemini 3 and it's completely insane. You can build full apps in one prompt. Now, I'm talking 3D games, Instagram, spy tools, entire SAS platforms. No coding needed. Everything just works. I'll show you exactly how to use it to automate your agency. Let's go. Okay, so Google released Gemini 3 on November 18th, 2025. And this thing is a monster. I've been testing it for days, and honestly, it's blown my mind. We're talking about an AI that can handle 1 million tokens at once. That's like reading 700,000 words in one go. It can process text, images, video, audio, and code all at the same time. And the best part, it scored 1501 on the ELO benchmark, which means it's beating GPT and Claude on real world builds. This isn't just hype. This is the real deal. Now

here's what makes Gemini 3 different from everything else. It has this thing called generative interfaces. Basically, the AI adapts its responses on the fly. It doesn't just spit out text. It can build interactive UIs, create agents that do multi-step tasks, and generate entire workflows from a simple prompt. So, there are two main ways to use Gemini 3. First is

Google AI Studio. Second is anti-gravity IDE. Google AI studio is completely free to start. You just go to a studio. google. com. No credit card needed. You can test Gemini 3, build prototypes, and create apps without paying a single dollar. Anti-gravity IDE is different. This is for developers and agency owners who want to build more complex stuff. You can find it at anti-gravity. google. It connects with Gemini Agent, which is this insane multi-step task system. I use this when I'm building client tools because it can debug code, fix errors, and even deploy apps automatically. All right, let me show you how to actually use this thing. First step, go to astudio. google. com. Click the start building button. Now you need to pick your model. You'll see Gemini 3 Flash and Gemini 3 Pro. Flash is faster. Pro is slower, but it has way better reasoning for the stuff I'm about to show you. Use Pro. Trust me. Next

you want to enable deep think mode. Now, here's where it gets fun. I'm going to show you three real builds that you can copy right now. First up, a lead magnet quiz tool for the AI profit boardroom. Second, an Instagram competitor analysis dashboard. Third, a voice AI agent for customer support. All of these were built with one prompt each. No coding, no technical skills, just good prompting. Before we keep going, I want to tell you about the AI profit boardroom. This is where we teach agency owners and entrepreneurs how to save time and automate their business with AI tools like Gemini 3. We're building real tools, real systems, real SOPs that you can plug into your business today. If you want to learn how to use AI to get more clients, automate your outreach, and build tools like the ones I'm showing you right now, check out the AI Profit Boardroom. Link is in the description. Okay, so the AI Profit

Boardroom needs a lead magnet quiz, something that asks visitors a few questions and then gives them a personalized AI automation plan. This is the exact prompt I used. Build a complete interactive quiz tool in HTML, CSS, and JavaScript. The quiz should ask five questions about the user's business, their biggest timewasting tasks, their current tools, their monthly revenue, and their automation goals. After they answer, generate a personalized AI automation road map with three specific tools they should use and why. Make it mobile responsive with a clean, modern design. Include email capture at the end so we can follow up. Add animations and make it feel premium. I hit enter and waited about 45 seconds. Gemini 3 Pro generated the entire thing. Full HTML file, all the JavaScript logic, CSS styling, everything. Working quiz, I tested it on my phone. Worked perfectly. This is what I mean when I say Gemini free is a game changer. You can build real client deliverables in under a minute. I didn't stop there. I asked Gemini to add a results page that dynamically changes based on the answers. So, if someone says they're struggling with content creation, the results page shows them AI writing tools and video generators. If they say they're struggling with lead generation, it shows them outreach automation and CRM tools. The whole thing took maybe 3 minutes total. And now the AI profit boardroom has a lead magnet that actually converts because it's personalized. Next example. Let's say

you're running an agency and you want to offer Instagram competitor analysis as a service. Your clients want to know what's working for their competitors. Normally, you'd have to manually go through competitor profiles, screenshot everything, analyze hooks and CTAs, write up a report. That's hours of work. Not anymore. Here's the prompt I used. Build an Instagram reels competitor analysis tool. The tool should accept an Instagram username. Scrape their last 10 reels using Appify API. Extract the hooks in the first 3 seconds. Identify all CTAs and calls to action. Analyze engagement patterns and suggest three improvements the user can make. Display everything in a clean dashboard with charts showing engagement over time. Include a download PDF button for the full report. Gemini [snorts] 3 generated the entire dashboard. It included the Appify integration. It built the UI with charts. It even added the PDF export function. I tested it with a competitor in the SEO space and it worked flawlessly. The tool pulled all their reels, analyzed the hooks, found patterns, and suggested improvements. Now, here's what's crazy. I asked Gemini to add a feature that tracks hook types. So, it categorizes hooks as questionbased, shock value, benefit driven, or curiosity gap. Then, it tells you which type gets the most engagement for that specific competitor. This is gold because now you know exactly what hook style to use. All right, last

build, and this one is wild. Voice AI agents are huge right now. Every business wants a voice bot that can answer customer questions, book appointments, take orders, whatever. Gemini 3 can do this in one prompt. Here's what I used. Create a multi- aent voice AI platform for customer support. The system should have voice input and output using web speech API. It should understand customer questions. Search a knowledge base for answers. Escalate to a human if it doesn't know and log every conversation in a simple dashboard. Include user authentication so multiple businesses can use it. Make it feel conversational and friendly. Deploy ready code only. Gemini built the whole thing. Voice input worked. Voice output worked. The agent actually sounded natural. It had a knowledgebased system where you can upload FAQs. It had escalation logic and it had a dashboard showing all conversations with timestamps and transcripts. I tested it by asking random customer service questions and it handled everything. This is a SAS product you could sell for $99 a month per business. And Gemini built it in one prompt. Now, let me tell

you the secret to making this stuff work. The secret is in the prompt. You need to be specific. Don't just say, "Build me a voice agent. " agent that does X, Y, Zed with features A, B, C, and make it look like this. " The more details you give, the better the output. Also, always specify the output format. Say, give me deploy ready code or give me production ready HTML. And always mention mobile responsive if it's a web app. Let me give you some pro tips. First, Gemini 3 is amazing at multimodal tasks. That means you can upload a photo and ask it to turn that photo into code. I tested this with a whiteboard sketch. I drew a rough layout of a landing page on a whiteboard, just boxes and arrows. I took a photo, uploaded it to Gemini, and said, "Convert this whiteboard sketch into a full landing page with HTML, CSS, and JavaScript. It worked perfectly. " Second tip, use vibe coding. Vibe coding is when you describe the vibe or aesthetic instead of technical details. For example, build me a retro80s dance party landing page with neon colors, animated backgrounds, synth wave fonts, and an RSVP form. Gemini gets it. I use vibe coding to build a landing page for an AI profit boardroom event and it came out amazing. Third tip, always ask for error handling. Add this to your prompts. Include error handling for all user inputs and API calls. This makes your code way more robust. Before we wrap up, I want to tell you about the AI success lab.
