A free course that builds your app with you
Six short lessons, taught by your own coding agent, on your own idea. Your app is live on the internet in the first lesson. By the last, you have tested with your own hands that one person cannot see another's things, the link looks right when you share it, and you have sent it to your first people.
You do not learn to code. You learn the part that is yours: saying what you want so an agent builds the right thing, checking that it did, and getting it in front of people.
Say what it is
- You do
- Describe your app as one person doing one job: who it is for, the one thing they do with it, and what they see when it worked.
- You have
- Your app at a live address, with sign-in working. You open it on your phone and use it.
- You keep
- An app is one person doing one job. Describe that, and the features follow.
Ask for a change
- You do
- Write one request in three parts: what you see now, what you want to see instead, and how you will know it worked.
- You have
- The first change you asked for yourself, live, and checked by you against your own test.
- You keep
- One change at a time, with a way to check it.
Who can see what
- You do
- Say in plain words who may see, change, and delete each thing your app saves. Then try to see something you should not, with two accounts in two browsers.
- You have
- An app whose rules you wrote down, and your own attempt to reach another person's things, refused.
- You keep
- Say who may see what. Then try to see something you should not.
When something is wrong
- You do
- Use your app the way a stranger would, find one thing that is wrong or confusing, and report it: what you did, what you expected, what happened.
- You have
- The fix live, and the list of every version of your app, any of which you can go back to with one sentence.
- You keep
- Say what happened, not what you think is wrong. Nothing is lost: you can always go back.
What a stranger sees first
- You do
- Choose the name and the one sentence that tell someone who has never heard of your app what it is. Send yourself the link and look at it as they would.
- You have
- A link that shows your app's name and sentence when it is shared, and a first screen that says what the app is. On your own domain name too, if you want one and are on a paid plan.
- You keep
- A stranger decides from the link and the first screen. Say what it is in one sentence.
Your first ten people
- You do
- Name five to ten real people who have the problem your app is for, and send them the link yourself with one thing to try.
- You have
- A way for people to tell you what they think, built into the app, and your first invitations sent.
- You keep
- Show it to ten people who have the problem, watch where they get stuck, and turn each thing they say into one request.
How a lesson works
Your agent runs the lesson. It asks you a question or two, builds, and puts the change online. Every lesson has one step that is yours and nobody else's: describing something, trying to break something, sending a message. Every lesson ends with something you can see on your own live app.
Go at your own pace. Stop after any lesson, or in the middle of one. When you come back, say "next lesson" and the agent picks up where you stopped. Each lesson is built to fit one sitting of about half an hour. Nobody has timed a full run yet, and the first lesson takes longer on a day you are also installing things.
It stays your app the whole way. If you would rather build something else for a while, tell the agent; the lesson waits.
What you need
- A computer, Mac or Windows.
- A coding agent: Claude Code, Cursor, Codex, or Copilot. This is the one thing you may pay for. Start here says what each one charges and walks through installing one, without a terminal if you prefer.
- An idea. One sentence is enough. Lesson 1 turns it into something an agent can build.
You do not need to have written code, used a terminal, rented a server, or set up a database or a login. Those come with the app.
What it costs
The course is free. It runs on the nerdsystem Free plan: one app, up to 1,000 people signing in a month, and no card. One optional step in lesson 5, putting the app on your own domain name, needs the Pro plan at $39 a month. Skip it and the course finishes the same.
Start lesson 1
Put in your email and your idea in a sentence, press Copy for your agent, and paste what it copies into your coding agent. The agent installs what it needs, signs you in with a link sent to that address, and begins the first lesson.
Paste it into Claude Code, Cursor, Codex, or Copilot: programs on your computer that run commands for you. A chat website like ChatGPT or claude.ai cannot. It is plain text written for the agent, and you see all of it when you paste it. New to Claude Code? In the Claude desktop app, click Code, choose a folder, and paste it there; in a terminal, type claude first.
The sign-in email creates your nerdsystem account. There is no password and no sign-up form.
Questions
Do I need to know how to code?
No, and the course does not teach it. Your agent writes the code and runs the commands. You say yes when it asks permission to run a step, and you do the one step in each lesson that is yours.
I already have an app on nerdsystem. Can I take the course on it?
Yes. Open the app's folder in your coding agent and say "start the nerdsystem course". Lesson 1 becomes describing the app you have, and the other five are the same.
I built my app somewhere else. Does the course work for it?
The course starts once the app is on nerdsystem. The screens carry over, the server and the sign-in are rebuilt on the platform's, and your users sign up again. The compare pages say what that means for each tool.
What will I not get?
A certificate, a promise of customers or income, or a programming education. The course can put a working app in front of ten people; whether they want it is between you and them. The checks nerdsystem runs before each deploy are not a security audit, and lesson 3 says what they can and cannot tell you.
Who is teaching, and what does nerdsystem see?
Your own coding agent teaches, following lessons that come with the nerd command it installs. There are no videos, no group, and no schedule. nerdsystem does not see your conversation with your agent. It receives what the nerd commands send: your sign-in email, the sentence the app is created with, a copy of the app's code with each deploy and each save, and which lessons are finished. The privacy policy has the full list.
What happens after lesson 6?
You keep building the same way: every change is lesson 2 again, and every problem is lesson 4. The Free plan covers one app and 1,000 people signing in a month. Pricing says what the paid plans add, and nothing asks you to move until you want something they have.
Would rather skip the lessons and just build? Start here has the same prompt without the course, and the guides go step by step for each agent.
