Your idea. Your project. Your curriculum.
Learn to code by building the software you actually want.
Describe your idea. Build Studio builds a small first version, you explore it and change it, then you rebuild it yourself, one step at a time, with a target for every step, a lesson written for your app, a tutor that gives hints instead of answers, and a checker that tells you how close you are.
A simple expense tracker that shows where the money goes each month.
Get it
Say what you want in plain English. In about two minutes you have a small working version: real HTML, CSS and JavaScript (or React, or Svelte) that you can read from top to bottom. It is checked in a real browser before you see it.
Explore it
Use it. Change it: "make the header blue", "add a delete button". Read the code behind every change. Things that need a server or accounts are parked for later, on purpose. When it feels like yours, lock it in.
Rebuild it
Your version becomes the target. A path of 10 to 20 steps is planned from a concept graph, sized to what you already know. You rebuild the app yourself, step by step, and the path keeps going: a Node server, then a database and accounts.
Target
A live preview of what your app should look like and do after this step, built from your own first version. Never a guess about what "done" means.
Lesson
Written just in time, for your app and your code, in simple English: why this step matters, the two or three ideas it needs, and the actions to take. No code to copy.
Tutor
Ask anything. It climbs a ladder: a nudge, then the idea, then a small example, then the shape of the answer. It points at your exact lines, and it never writes your app for you.
Check
A parity agent compares what you built with the target and the step's checks. For server steps it starts your server in a sandbox and makes the requests. You always know where you stand.
Pick your stack, keep your project
The same app goes all the way. Start in the browser, add a server, add a database and accounts. Nothing is thrown away between stages.
A real workbench, in the browser
Server steps run in your own Linux sandbox: Node, a terminal, git, Express, a private MongoDB, and a URL where your server answers. Your code is built and type-checked on every run, and the errors show up where you are looking.
- An editor with highlighting, formatting and search
- A terminal that runs one command at a time inside your sandbox
- Checkpoints you can go back to
- Isolated from everyone else, and from the internet
Starting from zero
Never programmed. You get the plain HTML, CSS and JavaScript path, small steps, and a first win in the first session.
Under two years in
You know the basics but have not shipped a full app. Skip what you know; the path starts where your gaps are.
Switching careers
Bring your own domain: a tool for the shop, the clinic, the classroom. The project is the portfolio.
Still looking for the first job
Build one thing end to end, understand every line, and be able to explain it in an interview.
What do you want to build?
An expense tracker, a habit board, a tool for your family's business, a clone of the app you use every day. Bring the idea; the curriculum follows.
