Introduction:
I just discovered the ridiculously simple one-page website that’s secretly pulling in almost $100,000 every single month from pure passive income.
Traffic and Revenue Numbers
So the traffic and revenue for the site are 1.6 million visitors, 5.39 pages per visit, and a $10 RPM. That’s nearly like six figures just from Google AdSense running on autopilot.

Building a Similar Website with AI
And here’s the crazier part. I’m about to guide you exactly on how to build the same type of website using just one AI tool. I have zero coding knowledge and zero web development experience, but in the next 15 minutes, I’m going to build an exact replica of this traffic-pulling machine.
We’re talking about AI doing all the technical work for us. Google AdSense integration, Stripe for premium features, and everything you need to create your own passive income website. And by the end of this article, you’re going to know exactly how to build a website from scratch.
Introducing the AI Tool: Replit
Now, the AI tool that we’re going to use today is Replit.
Project Goal: Photo Enhancement Web App
This project is all about recreating the magic of photo enhancement apps like Remedy, but doing it entirely inside of Replit using simple prompts and a few clever tools.
Now, the goal is to build a clean, fast, and monetizable web app that takes blurry or damaged photos and then turns them into something impressive in real time. We’ll include everything like real enhancement features, user accounts, premium upgrades, and even ad revenue.
Starting with the Layout
But first, it all starts with the layout.
Initial Prompt for Web App
So to begin, we’re going to ask Replit to build a responsive web app using HTML, CSS, and JavaScript. Include navigation sections like home, upload, enhance, history settings, and premium. Ensure fast routing between sections without full-page reloads.
Important Disclaimer
Important disclaimer: building websites and making money online is not easy. Despite what other bloggers are saying, when I guide you on how to build a website, I’m demonstrating the technical process and the potential. I am not generating your results.
These AI tools are legit and the techniques do work, but success depends on your execution, timing, and honestly, some luck. Most websites don’t make money immediately, and many don’t make money at all.
So, I’m not promising that you’ll get rich or that you’ll quit your job. This is not financial advice or a get-rich-quick scheme. I’m just guiding you on what’s possible with these tools. What you do with that knowledge, well, it’s entirely up to you.
Replit Response
So, all right, with expectations set, let’s go ahead and continue building the app. So after we give that prompt, Replit responds by setting up the foundation with dynamic routing between pages so that everything loads instantly without having to refresh the whole browser.
Now each section—home, upload, enhance history settings, and premium—gets its own dedicated view, and the navigation bar stays fixed while adapting nicely to smaller screens. It’s a solid starting point that already feels like a real web app.

Building the First Feature:
Photo Upload and Enhancement
One of the first things we want users to try, of course, is uploading a photo and watching it improve right away. It’s a quick win that shows off what the app can do, and it sets the tone for the rest of the experience.
Uploading and Enhancing Photos
First User Experience
One of the first things we want users to try, of course, is uploading a photo and watching it improve right away. It’s a quick win that shows off what the app can do, and it sets the tone for the rest of the experience.
Creating the Enhancement Interface
So, that’s the next feature we’re going to build. And to do that, we’ll just have to ask Replit to create the enhancement interface with this prompt.
“Create a component where users can upload a photo, JPEG or PNG. Show a preview and an enhance now button. Simulate enhancement by applying placeholder effects. Sharpen D noise is upscale. Show the enhanced image beside the original.”
Placeholder Enhancement Effects
So with that, Replit sets up the component just like we asked. Users can upload their images, which instantly appear in the preview window. So, when they click enhance now, placeholder effects kick in to simulate a sharper, cleaner version of that photo. The enhanced result shows up right beside the original, and that makes it easier to compare the before and after.
Optimizing the Interface
Simplifying the Process
After some hands-on testing, I’m also thinking about, you know, just simplifying the interface even more. The separate enhance page isn’t really necessary if you think about it. It just adds an extra click.
Refining the Layout
So, we’re going to go back to Replit and enter this follow-up prompt.
“Optimize the front end and improve the UI UX. Remove the enhanced page since it is not needed. Remove the general file upload as well.”
Streamlined Experience
So, after those changes are applied, everything feels a lot tighter. The upload and enhancement features now live in one streamlined view with no distractions or any extra steps. It’s a lot faster, it’s clearer, and it is a much smoother experience overall.
Adding Multiple Enhancement Modes
Addressing Different Image Needs
Once those basic enhancements are working, our next step is giving our users more control over how their photos are processed because not every image needs the same treatment. Some are selfies, others are old scans, and a few just need heavy cleanup.
Defining Enhancement Modes
So, with that, we’re going to build in multiple enhancement modes that our users can choose from. So for this part of the process, we’re going to go ahead and tell Replit to add facial feature enhancement. For example, sharpen facial detail, smooth skin, do old photo restoration, simulate damage repair, and do noise reduction. Prior to processing, let users to pick between the following enhancement types: basic, face, vintage, and noise reduction.
Preset Options Created
Replit then creates four preset alternatives in response. First is basic, which does general upscaling, face-based touch-up for selfies, vintage photo restoration designed to, you know, restore older or faded images, and finally, aggressive noise reduction. Our users can select one of these modes before running the enhancement.

Improving the Mode Selector
Identifying a UI Problem
However, the mode selector to me feels a little bit clunky. Switching between options isn’t very intuitive.
Updating the Interface
So, I’m going to go back and simply ask Replit to refine the interface with this follow-up prompt. “I can’t properly choose enhancement types; improve that interface to be more user-friendly.”
A Visual Solution
Replit will modernize the user interface by transforming the mode options into a more graphical component, such as label tabs or buttons with icons.
Introducing User Accounts and Galleries
Why User Accounts Matter
As more features get added, we have to start thinking about user accounts because if someone enhances a photo, you know, they should be able to come back to it later and still find it there, especially if they’re using the app regularly.
Setting Up Authentication
I will thus use Supabase to create up authentication and personal galleries in this next phase. To enable login and private galleries, all we have to do is go back to Replit and say add superbase authentication email/pass.” After login, let users view previously enhanced photos under their account with preview thumbnails and timestamps. Store image metadata in Supabase.
Connecting Supabase
And with that, Replit sets up Supabase to handle login, registration, and secure user sessions. During setup, it’s asking for the Supabase credentials. So, all we have to do is go back to our Superbase from the Superbase dashboard and then plug them in and everything connects smoothly from here on out.
Personal Gallery
Once someone does log in, they’re shown a personal gallery with all of their previously enhanced photos. For convenience, each has a timestamp and thumbnail. Now, in the background, a superbase keeps track of each saved photo along with details like when it was enhanced and which user it belongs to.
Fixing a Gallery Bug
But after enhancing a photo, a notification confirms it’s saved, but nothing shows up in the gallery view. So, we’re going to ask Replit to help us troubleshoot with this follow-up. I get a notification about an enhanced photo saved to the gallery, but I don’t see it on the gallery page.
Resolving Permission Issues
Now here it turns out there was a mismatch in superbase permissions. So after following the replits, the gallery updates correctly and our saved photos become visible right after enhancement.
Adding Premium Features
Why Premium Features Matter
As the app grows, some users might want advanced functionality beyond the free features. Introducing premium features allows us to monetize while still keeping a free option for everyone.
Defining Premium Options
So, for the premium upgrade, we’re going to offer higher-resolution exports, unlimited enhancements, and priority processing. This ensures that people who pay get real value while casual users still enjoy the free version.
Setting Up Payment Integration
To handle payments, we integrate Stripe. This allows users to upgrade securely with credit cards or digital wallets. Replit can help us build a subscription model with Stripe integration, payment confirmation, and access control based on the user’s subscription status.
Subscription Flow
When a user opts for premium, they see a simple model showing benefits, pricing, and a checkout button. Once the payment goes through, their account status updates instantly to premium, unlocking all the new enhancement modes and higher-resolution downloads.
Exporting and Downloading Photos
Export Options
Users can download enhanced photos in JPEG, PNG, or even higher-resolution formats if they’re premium. Each download preserves the enhancements exactly as they appear in the preview.
Implementing Download Functionality
We create a “Download” button next to the enhanced image. When clicked, the app generates the selected format and resolution, then starts the download automatically. Premium users see an additional “High-Res Download” option.
Preserving Metadata
Along with the photo, we keep metadata like enhancement type, date, and user ID embedded. This is useful for tracking, analytics, and personalized experiences in the gallery.
Analytics and Tracking

Understanding User Behavior
Understanding how consumers engage with the app is crucial. Analytics allow us to see which enhancement modes are most popular, how often users return, and what drives premium conversions.
Integrating Analytics Tools
We integrate tools like Google Analytics and custom Supabase tracking to monitor clicks, uploads, downloads, and enhancement types selected.
Using Data to Improve UX
The analytics dashboard helps us identify bottlenecks and optimize the interface. For example, if many users struggle to find the download button, we can redesign it for better visibility.
Notifications and Feedback
Keeping Users Informed
Notifications improve engagement by letting users know when enhancements are complete, premium benefits are available, or new features are released.
Implementing In-App Notifications
We build a notification system showing pop-ups, banners, and emails. These are triggered by user actions, like completing an enhancement or upgrading to premium.
Collecting Feedback
User feedback is critical for continuous improvement. We ask users to review the experience and provide comments following each improvement. This helps identify bugs and areas for improvement.
Preparing for Launch
Final Testing
Before public release, we thoroughly test all features: photo uploads, enhancements, premium subscription flow, downloads, analytics, notifications, and galleries.
Fixing Bugs
Any issues, like gallery glitches or failed downloads, are fixed based on test results. Reliability checks are performed on Stripe integration, API requests, and Supabase permissions.
Launch Strategy
We prepare marketing materials, demo videos, and social media posts to attract early users. Early adopters can try the free version, share feedback, and spread the word about the app.
Integrating Google AdSense

Adding Ads Without Disrupting UX
Even free users can generate revenue through ads. The objective is to incorporate Google AdSense without interfering with the user experience.
Setting Up Ad Slots
We add responsive ad placeholders in strategic areas: the homepage, the upload section, and the free result viewer. These ads are visible but unobtrusive, maintaining a clean interface.
Verifying Ownership
Once ad slots are in place, the website is submitted for AdSense review. Upon approval, the verification code is added to the HTML head section to confirm ownership.
Displaying Ads
Live ad units automatically appear in designated slots after verification. Users can continue enhancing photos without intrusive pop-ups or interruptions.
Scaling User Engagement
Encouraging Return Visits
User accounts and personal galleries encourage repeated usage. By storing previously enhanced photos, users are more likely to return to the app.
Enhancing Mobile Experience
The vertical layout for multiple enhancement variants ensures smooth scrolling on mobile devices. Mobile-friendly navigation improves engagement and overall usability.
User-Friendly UI
Refinements like icon-based enhancement modes, intuitive sliders, and clear download options make the app more approachable for all user levels.
Continuous Enhancement Options
Multiple Enhancement Variants
Users can generate up to 18 enhancement variants, allowing them to explore different styles, colors, and details.
Comparison Tools
A side-by-side toggle and before-and-after sliders let users compare their preferred variant with the original image for maximum clarity.
Customization Controls
Users can toggle elements like backdrop pop, face beautify, and color boost, as well as change the level of the augmentation. These changes are reflected in real time in the preview.
Monetization Strategy

Free Users Drive Traffic
Free users are crucial because their engagement generates page views, which can be monetized through AdSense.
Premium Subscriptions
Premium subscribers unlock all 18 enhancement variants, high-resolution downloads, and advanced editing controls. The subscription flow is seamless through Stripe integration.
Ad Revenue Integration
Ads are placed thoughtfully so that the core user experience remains smooth while generating passive income from free users.
Final App Review
Full Feature Set
The app now includes:
- Image upload and enhancement
- Multiple enhancement modes and variants
- Personal galleries and user accounts
- Premium subscriptions with Stripe checkout
- Responsive Google AdSense integration
Seamless User Flow
Users can easily navigate between features, upgrade to premium, download images, and explore multiple variants without friction.
Ready to Scale
With all core features implemented, the app is fully functional and ready to scale as traffic increases.
Conclusion
Recap of the Process
From a simple AI prompt to a fully monetizable web app, every feature—photo enhancement, subscription flow, gallery management, and ad integration—was created using Replit without writing a single line of code.
Empowering Passive Income
The same model can generate significant revenue, similar to the one-page website earning nearly $100,000 per month.
