What if I told you that a simple, one-page website is secretly generating over $15,000 every single month with almost no effort? It’s true. Just look at the analytics: a basic time zone converter app is getting 1.5 million monthly visitors, pulling in a $10 RPM, and creating massive passive income through Google AdSense.
Most people assume you need years of coding experience to build something like this. But you can do it with absolutely zero coding knowledge and zero web development experience. In this guide, we’ll recreate this exact money-making website using just one AI tool. We’ll let artificial intelligence handle all the technical features, connect it to Google AdSense for ad revenue, and add Stripe for premium features. By the end, you’ll have a complete blueprint for building your own passive income website. This is the future of online business—while everyone else is still learning to code, we’re letting AI do the heavy lifting to start generating income.
The AI tool we’ll use is Replet.
Laying the Groundwork
We’ll start by focusing on creating a clean, one-page web app that helps users convert time zones and calculate time or date differences. The goal is to build a straightforward, user-friendly layout with distinct sections:
- Time zone conversions
- Time/date calculators
- Meeting planners
- An AI assistant
Here is the prompt we’ll give Replet to start:
“Build a one-page web app. The app should have a clean and modern user interface and be designed to help users convert time zones and calculate time date differences. The page layout should include sections organizing the single page layout to include time zone conversions, time date calculators, additional utility tools like meeting planners, and an AI assistant.”
Once you give Replet this prompt, it will display a visual preview of the app. If everything looks good, you can approve the plan to begin building.
Building the Core Features
Global Time Zone Converter
The first key feature is a global time zone converter that allows users to effortlessly compare time across different locations worldwide. It will support major time zones from hundreds of cities across North America, Europe, Asia-Pacific, Africa, and South America to ensure accuracy.
The prompt for Replet:
“Add time difference converter among different time zones worldwide, allowing users to easily compare two or more locations. This feature should support major time zones across North America, Europe, Asia-Pacific, Africa, and South America, and must cover hundreds of cities and regions globally to ensure worldwide accuracy.”
Once the section is updated, users can either search or select cities from a dropdown menu to instantly see the time difference between two or more locations. The app will also allow you to compare up to eight time zones at once.
Time and Date Calculators
Next, we’ll add a tool that lets users quickly add or subtract time, or figure out the exact duration between two dates or times. This feature is advanced enough to take daylight saving time into account, ensuring all calculations are perfectly adjusted based on location and season.
The prompt for Replet:
“Include time and date calculators for various time related computations such as adding or subtracting time or calculating durations between two dates or time. Be sure to include daylight saving time information and handling so all calculations adjust correctly based on the location and season.”
With this feature, users can check how many days are between two dates or figure out what time it will be 10 days from now in a specific location, with accurate results that account for daylight saving time.
Additional Tools
Scheduling meetings across different time zones can be a headache, especially with daylight saving time changes. To solve this, we’re adding a meeting planner feature. This tool will help users easily find the best time to schedule calls or events. It provides a timeline view that lays out all selected time zones side-by-side and clearly marks optimal working hours.
The prompt for Replet:
“Provide users with meeting planners and daylight savings time information, making it easier to schedule calls or events across different regions. Also integrate a time zone search functionality to let users quickly find a city or zone and display a complete list of worldwide time zones for quick reference.”
This feature makes it simple to find a perfect meeting time, no matter where your participants are located.
AI Assistant
To make the app even smarter and more user-friendly, we’re adding an AI assistant. Instead of manually filling out details, users can simply ask the app questions in natural language, making time-related queries feel like a simple conversation.
The prompt for Replet:
“This feature should use natural language processing for complex time queries like ‘what time will it be in Tokyo when it’s 3:00 p.m. tomorrow in New York?’ and it should also include smart meeting time suggestions for multiple participants in different time zones.”
With the AI assistant running, users can type their questions in plain language, and the app will understand and provide the correct answer instantly.
Monetization: Making It a Business
The real fun begins when you figure out how to make money. We’ll add two key monetization methods: Google AdSense and Stripe.
Google AdSense
We’ll integrate Google AdSense to generate revenue from ads placed in non-intrusive locations, like sidebars or between tool sections. The ad placeholders will be designed to blend in seamlessly with the app’s style.
The prompt for Replet:
“Add Google AdSense to the website to show ads or ad banners, placing them in non-intrusive locations such as sidebars or between tool sections. The ad placeholders should look exactly like real Google AdSense ads with Google’s standard ad styling and format.”
After adding the ad placeholders, you’ll need to sign up for Google AdSense and paste your code snippet into Replet. Once your account is approved (which can take a few weeks), the ads will start appearing on your site.
Stripe for Premium Features
To add a premium revenue stream, we’ll integrate Stripe. This will allow users to unlock premium features like full access to the AI assistant and advanced scheduling tools.
The prompt for Replet:
“Add Stripe to unlock premium features such as full access to the AI assistant and advanced scheduling tools for professional users. Use the Stripe checkout page for payment.”
Once you enter your Stripe API keys into Replet, a premium button will appear on your site. When a user clicks it, they will be redirected to a secure payment page. After the payment is processed, all previously locked premium features will be unlocked, and the user’s dashboard will display a premium badge, confirming their full access.
And there you have it. We’ve set up the core features, integrated ads, and unlocked premium tools—all without writing a single line of code. This is just the beginning. The potential for building profitable online businesses with AI is limitless.
