Hands-on Course: Building Profitable Websites with AI

With a single website,
reach users on PCs and smartphones.

A responsive website is a website whose layout and size adjust to fit the screen. Users can access it at the same URL from PC and mobile browsers without installing a separate app.

Start with a small single-page site. Build three common tools and one tool based on your own idea, then check how they look and work on mobile screens. Next, practice attracting visitors through search and managing AdSense, then expand it into a web service by adding login, data, and test payments.

Web fundamentals → AI creation and review → Deployment and search → AdSense → Service operation and improvement

If you watched YouTube and thought, “I want to try that too,” now you can bring your own idea to life. We’ll cover how to build a website and how to operate it after it’s built.

Plan → build with AI → review it yourself → operate and improve.

We don’t stop at a single good prompt. We build the habit of connecting the user’s problem, a working result, and the validation record.

Before enrolling, please check whether this aligns with your expectations.

This is not a course that guarantees passive income or AdSense approval, nor does it provide development outsourcing. You will need time to practice hands-on and verify the results. It is also not suitable for those looking for an advanced development or large-scale infrastructure specialization course.

Start with a small achievement, but set clear completion criteria.

Create a page containing your name and open your URL on your phone. Check that the text is easy to read and that the buttons and tools work properly on both PC and mobile. Then, review whether only your data is visible and whether changes can be reverted, expanding it into a web service that can be operated reliably.

How do “profitable websites”
start monetizing?

The starting point is a small tool that solves someone’s problem. You build the necessary features, reach users through search, and improve the content and functionality based on visitors’ responses. To this, you connect the process of trying to monetize through AdSense ads.

Afterward, we will implement a structure in a test environment where members can save their own records and use buyer features. Going one step beyond ad monetization, you will learn the foundation for expanding it into your own service.

“Money-making” means creating and operating with monetization as the goal; it does not guarantee revenue or AdSense approval. You will learn how to improve by identifying users’ needs and evaluating actual operational results.

The payment exercises use a test mode with no actual charges. Actual sales require separate operational preparations, including contracts, review, security, and refunds. The course distinguishes between test implementation and the items to check before switching to live payments.

Before enrolling, check the cost and requirements first.

Required setup: A PC, internet access, basic file and folder skills, and an environment where you can create accounts and check email. The main hands-on practice uses VS Code, Claude Code, Next.js, GitHub, and Vercel. For instructions on installing and using Claude Code, see the official documentation at code.claude.com/docs.

Costs beyond the course fee: A subscription or API usage fee to use Claude Code, domain registration and renewal fees, and hosting costs suitable for commercial operations. Additional costs for databases, APIs, and other services may arise depending on usage. Check the official information available at the time of payment for pricing, limits, exchange rates, and taxes.

Important: Vercel Hobby is for non-commercial use. For commercial operations, including AdSense ads, you must check the terms of the commercial plans. Do not calculate the course cost on the assumption that you can “continue monetizing with free hosting.”

The home server section is optional. You can learn the remaining sections without purchasing separate equipment. If you choose to use equipment, electricity costs, networking, backups, security, and incident response also become the operator’s responsibility.

Materials to use when practicing alone

• Website planning document and AI work and review guide md

• Step-by-step prompts and an error and recovery log template

• Deployment, search registration, AdSense, and security checklist

• Login · RLS · Test Payment Verification Checklist

• Learning progress tracker, section-by-section completion checklist, weekly operations, and 30-day action plan

The materials are not answer sheets to simply copy and paste and be done with; they are working tools to fill out and verify according to your own site. AI results and tool screens may vary depending on the timing and environment.

We explain the course format and set expectations.

This is a hands-on VOD practice course that you follow along with directly. For questions about the course content, please use Inflearn’s Q&A section. Individual service development, 1:1 mentoring, real-time consultations, and approval assistance are not included.

Search indexing and AdSense reviews are subject to the decisions and schedules of external services. To avoid stopping while waiting, we work in parallel on improving content, validating with users, and the next hands-on exercise.

The public release schedule and video upload status will be finalized and announced when the course launches. Set your learning plan around verifiable outcomes such as “my URL is accessible,” “only the data I entered is visible,” and “I can undo changes”, rather than progress.

Frequently Asked Questions

Q. Do you create separate websites for PC and mobile apps?

No. We create a responsive website that uses the same URL on PC and mobile browsers. We adjust the layout to fit the screen size and review the functionality. This is not a process for creating native iOS and Android apps registered on app stores.

Q. Is this a course that only teaches AdSense?

AdSense is your first monetization experiment. You’ll learn the fundamentals of the web, AI-powered creation, deployment, search, and analytics, and in the latter part, you’ll connect memberships, a database, and test payments to build the foundation for running your own service.

Q. How much can I earn? Do you guarantee AdSense approval?

We do not guarantee specific earnings, visitor numbers, search rankings, approvals, or the time required to achieve them. The instructor’s YouTube figures are a personal example and not projected earnings. The goal of this course is to develop the operational skills to build, deploy, apply, analyze, and improve your own services.

Q. Is real money charged?

P7 is a hands-on exercise using Toss Payments test keys, with no actual charges. Before selling for real, preparations are required for contracting, review, business operations, security, refunds, and more, which are separated into a checklist. A successful test is not considered readiness for live payments.

Q. Is a home server and separate equipment absolutely necessary?

No. P8 is an optional section, and you can continue the rest of the learning using cloud hosting. With a home server, the operator is responsible for the equipment, electricity, network, backups, security, and handling failures. When installing it, data on existing disks may be erased, so dedicated equipment and backups are necessary.

Make a website based on your idea,
and now get someone to use it.

Build it with AI, check it on PC and mobile, and reach users through search. Try monetizing with AdSense, review operational data, and choose your next improvement.

From a single working website to my first business—one I understand and operate.
