Build Your First App with AI
Go from zero coding knowledge to a real, shippable web app plan: describe what you want, read what the AI writes, fix it when it breaks, and put it online.
Why learn Build Your First App with AI?
You do not need a computer science degree to build software anymore, but you do need a skill almost nobody teaches: describing what you want precisely, reading what the AI gives back, and steering it when it goes wrong. That skill is learnable, and this course teaches it from absolute zero. No coding background is assumed at any point.
Most vibe-coding tutorials end at the magic demo. This course prepares you for what actually happens next: the error message in red, the feature that silently breaks an old one, the moment the AI cheerfully offers to add a login system you have no way to check. You learn the loop that keeps you in control, the reading skills to see what changed, and the safety lines that keep your first app from hurting you or anyone else.
By the end you are not holding a toy from a tutorial. You leave with a complete written build plan for an app you chose, a reusable prompt pack that takes any idea from blank page to live URL, and the judgment to run that plan with whatever AI tool you have.
Who this course is for
- Students of any major who want a real app for their club, project, or portfolio
- Complete beginners who have never written or read a line of code
- Founders and side-project builders who need a v1 without hiring anyone
- Tutorial-bouncers who can follow along but freeze the moment something breaks
What you'll build and practice
- The ability to read AI-generated HTML, CSS, and JavaScript well enough to know what it does and where to change it
- A one-page spec method (pages, actions, data, look) that turns the picture in your head into a plan an AI can build from
- A debugging routine: the three-part bug report, regression recovery, and save points that make breakage boring
- A working mental model of hosting, deploys, domains, and how updates reach your visitors
- A capstone blueprint and seven-prompt pack for the app you pick: portfolio site, club signup sheet, or flashcard app

Course curriculum
32 lessons across 7 modules. Lessons marked Free preview are readable without an account.
Module 1. From Idea to App
What building with AI actually feels like, the tools you'll use, and the loop you'll run for the rest of the course.
- 7mYou Can Build Software NowFree preview
For decades, making software meant years of study. That door is open now. Watch one real build conversation and learn the two jobs that are still yours.
- 7mWhat a Web App Actually IsFree preview
The genie hands you 'a web app'. What is that, physically? Files. Just files, and a browser that reads them. Plus the three jobs every app does.
- 8mYour First Build ConversationFree preview
Four messages. One working flashcard app. Watch StudyDeck get born, including the moment a vague wish goes sideways and how one precise word fixes it.
- 6mTools of the Trade
Chat assistant, AI app builder, AI code editor: the three kinds of places a build conversation can happen, and why starting beats shopping.
- 7mThe Ask-Look-Adjust Loop
The rhythm behind every successful build gets a name: ask small, look every time, adjust with specifics. Master the loop and the rest is details.
Module 2. Read the Code
You'll never write code from scratch in this course, but you'll always read it: the skeleton, the clothing, the brain, and where each one lives.
- 8mHTML: The Skeleton
The genie hands you files full of angle brackets. Time to read them. HTML is the skeleton: labeled containers that decide what exists on your page.
- 8mCSS: The Clothing
Every rule answers two questions: who gets dressed, and what do they wear? Learn to read selectors, properties, and those mysterious #FFD700 color codes.
- 8mJavaScript: The Brain
Skeleton and clothing make a page that just stands there. JavaScript is the brain: instructions that wait for your click and then act.
- 7mWhere Things Live
One body, three drawers: index.html, style.css, script.js. How the files find each other, and what happens when a name doesn't match.
- 9mPractice: Tour of a Real App 💪
No new ideas, just reps: walk through every line of the real StudyDeck v0, all three drawers, and prove to yourself you can read a whole app.
Module 3. Say What You Want
The difference between a wish and a spec, and how to hand the genie one wish per message with the evidence it needs.
- 7mA Screenshot in Words
The genie can't see the screen in your head, so you have to send it a screenshot made of words: regions, exact labels, counts, and positions.
- 8mThe One-Page Spec
A wish describes a moment; a spec describes an app. Four short sections, one page of writing, and the genie can build the whole thing: Pages, Actions, Data, Look.
- 7mOne Wish per Message
Five wishes in one message feels efficient, right up until two old features break and you can't tell which wish did it. The case for going one at a time.
- 7mShow, Don't Just Tell
Some conversations stall no matter how precisely you describe. The unlock: stop describing the thing and paste the thing itself.
Module 4. Tweak and Fix
Small edits you can make with your own hands, and what to do the day the genie breaks something that used to work.
- 7mEdits You Can Make Yourself
Asking the genie to change one word is like calling a plumber to refill the soap. Some edits are faster with your own hands, and this lesson shows you which ones.
- 7mFind Where the Data Lives
StudyDeck only knows three cards. You want more. The fastest way to add them isn't an ask, it's finding the one place in the code where the cards actually live.
- 8mWhen the AI Breaks Things
You ask for one new feature. The genie delivers it, and quietly breaks one you already had. Here's why that happens and how to catch it fast.
- 8mThe Debugging Conversation
Red text in the browser's console feels like a verdict. It's actually a clue, often the best one you'll get. Learn to read it and to hand it over properly.
- 7mSave Your Working Versions 💾
One day a big ask will go wrong and take working features with it. Whether that costs you five minutes or a whole evening depends on one habit you can start today.
Module 5. Put It Online
What hosting actually is, how one-click deploys work, what a URL is made of, and how updates reach your visitors.
- 6mWhat Hosting Is
You want to send your mom a link to StudyDeck. Right now the app lives in a folder only your laptop can see. Meet the computer that never sleeps.
- 7mOne-Click Deploys
Getting your files onto a host used to be an ordeal. Today it's a drag, a drop, and a link. Here's the whole flow, plus the free-tier question everyone asks.
- 7mLinks, Domains, and the Padlock
Your app has an address now. Learn to read every piece of it, when a bought name is worth the money, and what that padlock actually promises (less than you think).
- 7mUpdating a Live Site
You fixed the typo on your laptop an hour ago. The live site still proudly displays it. Nothing is broken: you just met the two-copies rule.
Module 6. Data and Safety
Where app data actually lives, the lines you never cross with secrets and other people's information, and a checklist before anything goes public.
- 8mWhere Your Data Lives
StudyDeck remembers your cards between visits, with no account and no help from the host. Where's that data actually kept, and when does that stop being enough?
- 7mNever Paste Secrets
Some services hand you a key so your app can use them. Two rules keep that key from becoming your most expensive mistake, and both fit on a sticky note.
- 7mFeatures You Can't Check
The genie will build you a login page or a checkout form without blinking. Whether you should SHIP one is a different question, with a one-line answer.
- 7mWho Owns What
Your app is built from your ideas, the genie's code, maybe a photo you found and a font you liked. Who owns which part? A plain-language orientation.
- 8mPractice: The Pre-Ship Safety Checklist 💪
Everything from this module, compressed into six lines you run before any app goes public. Then four fresh scenarios to sharpen it on.
Module 7. Capstone and Beyond
Scope a real v1, write the blueprint and prompt pack, supervise a full simulated build, and choose your next road.
- 8mCapstone: Pick and Scope
Time to build something that's yours. First skill of the capstone: choosing an app you'll actually finish, which means choosing what NOT to build.
- 8mCapstone: Blueprint and Prompt Pack
Assemble the course's final artifact: a one-page blueprint of your app, and the seven numbered prompts that will build it. Written before you talk to the genie at all.
- 9mCapstone: Build Day
The full Film Club build, prompt by prompt: the plan, the skeleton, a color the genie freelanced, a feature that works, and a regression hiding in plain sight.
- 7mWhere to Go Next
You came in unable to code and you're leaving with a shipped app and a working method. One last look at everything you carry now, and the two roads onward.
Frequently asked questions
- I have zero coding experience. Can I really follow this?
- Yes, the course is written for exactly that starting point. Every technical word is explained in plain language the first time it appears, you never write code from scratch, and every exercise is about reading, judging, or making one small edit to code you are shown. If you can describe what you want and look carefully at what you got, you can do this.
- How is this different from AI-Assisted Development?
- They sit on the same ladder. This course is the on-ramp: it assumes no coding knowledge and teaches you to build one real app by directing an AI, reading its output, and shipping it. AI-Assisted Development is the next rung, written for people who already read beginner-level code and want professional-grade review and verification skills. Finish this course and you meet its entry requirement.
- Do I need to pay for an AI tool or a hosting service to take it?
- No. The course teaches tool categories rather than one product, and everything it asks you to understand works with the free tier of a chat assistant, an AI app builder, and a hosting service. Named examples are included as of mid-2026, but the skills are written to outlive any single product.
- Will my app actually be online at the end?
- The course ends with a complete, written build plan plus a prompt pack, and a full simulated build day that takes an app from blueprint to live URL, including a bug hidden in the build for you to catch. Running that plan on your own app is designed to be an afternoon of work with the tool of your choice.
- What about accounts, payments, and user data? Can the AI just add those?
- It will offer to, and a full module teaches you why to say no for now. You learn the difference between data that can live in the browser and data that needs a real backend, why secrets never go into chats or shipped files, and the red line: never ship a feature you cannot personally check. That judgment is what keeps a first app safe.
