Nexi
Start learning

I'll teach you how to build real software.

Start at your level. Learn by doing. Build things that actually work.

“Let's find your starting point.”

You don't choose a random course here.
Nexi finds your starting point first.

First, I find your level.

No two students should have to start in the same place. Tell Nexi what you’ve done before, then show what you know. Nexi finds the right starting point for you.

You

“I’ve built websites before, but JavaScript still confuses me.”

Nexi

Great. Let’s check a few things so I can find your level.

JavaScript

Question 1 of 5

What does this return?

const total = 5 + "2"
  • A7
  • B"52"
  • CError

Example placement question

Your skill profile

  • HTMLStrong
  • CSSComfortable
  • JavaScriptNeeds work
  • GitJust starting

You already understand HTML and CSS, so we’ll skip the basics and start with JavaScript. I’ll introduce Git alongside your projects.

  • Git & GitHubNext
  • ReactLater

Then, we learn.

Learn with a teacher, not a playlist.

Short lessons. Real practice. Ask questions whenever something doesn’t make sense.

JavaScript Fundamentals

Functions

Example lesson

Functions let you reuse code and keep your programs organized.

function greet(name) {
  return "Hello, " + name;
}

Try it

Create a function that returns the sum of two numbers.

function sum(a, b) {
  // your code here
}

  • Interactive lessons

    Clear explanations with real examples.

  • Practice as you learn

    Hands-on exercises and immediate feedback.

  • Ask Nexi anytime

    Get a hint, example or another explanation.

  • Talk it through

    Speak with Nexi when talking is easier than typing.

Practice what you learn.

Understanding something is different from being able to use it.

Practice

Fix the code

There’s a bug in this function. Can you fix it?

function withTax(price) {
  const tax = "0.2";
  return price + price * tax;
}
Check my answer

Correct!

Nice. The tax value needed to stay a number instead of becoming a string. That’s a common mistake.

  • Guided exercises
  • Real-world scenarios
  • Instant feedback
  • Build confidence

Then, you build something real.

What you learn doesn’t stay inside a lesson. Turn it into software you can run, improve and ship.

  1. Lesson

    Learn the concept

  2. Practice

    Apply your skills

  3. Project

    Build something real

  4. Working software

    Run, improve and share

An illustrative demonstration: building from a vague prompt causes repeated corrections, while Nexi Architect asks the important questions first and produces one build-ready prompt.

Without Nexi

“Build me a restaurant booking app.”

  • Change authentication
  • Fix booking flow
  • Rework database
  • Add cancellations

More corrections. More credits.

With Nexi

  • Who can make a booking?
  • How should bookings be confirmed?
  • Who manages availability?

Build-ready

One complete prompt with everything your builder needs to start correctly.

One clear plan. One powerful prompt.

Nexi Architect

Stop rebuilding.
Start with the right prompt.

Nexi thinks through your product before your builder writes the first file. You spend fewer credits fixing things later.

Prompt improvers rewrite what you said. Nexi figures out what you forgot.

Plan with Nexi

Use your build-ready prompt in Nexi Studioor the builder you already use.

Lovable · Bolt · Replit · Cursor · Claude Code

Nexi Studio

Describe it.
Watch Nexi build it.

Start with an idea or bring your plan from Nexi Architect. Nexi turns it into real files, runs your project, checks the result, and helps you improve it through conversation.

Preview everything as you build — desktop, tablet and mobile — and inspect the code whenever you want.

  • Build with conversation
  • See the real result
  • Understand the code

  1. Your idea

    You have an idea for a product.

  2. Nexi Architect

    Think it through. Define purpose, users, features and rules.

  3. Build-ready plan

    A structured plan and build-ready prompt.

  4. Nexi Studio

    Nexi builds it. Real files, live preview, and automatic checks.

  5. Working software

    A working product you can launch and keep improving.

Nexi, your teacher: a friendly character with a cream retro monitor head and a teacher's blazer, waving hello

One teacher.
Your whole journey.

The same teacher follows you from your first lesson to the software you ship. You don’t get a different AI in every tool.

  1. Learn
  2. Practice
  3. Talk

  6. Review

In practice

“You needed help understanding JavaScript closures.”

Later, in your project

You’re using the same closure pattern we practiced earlier. Want me to walk through how it works here?
