Agile System Software · Learn
Learn a modern language one checked step at a time
Java, Angular, .NET, Python and Rust at four levels, from a child's first printed picture to a tested service. Every course is a sequence of short mini steps — predict, lesson, live demo, your own hands-on, a machine check — written so an AI tutor can follow it with you in a browser-based VS Code seat.
20 courses · 150 sessions · 800 mini steps · 108 hours of lessons · 799 machine checks. Learn them with the AI tutor at codingtutor.agilesystemsoftware.com; new accounts start free with Java from zero (JV050).

How a step works
Predict, then learn
Before each idea you answer one quick question with a button. Then the tutor explains the idea in two or three plain sentences — no slides, no jargon first.
Watch, then do it yourself
The tutor builds the demo live in its own file in your seat and narrates. Then you build your version in your file; the tutor may hint, but it never types in your hands-on file.
The machine checks your work
Your code is run, tested or inspected in your own seat. A pass is recorded as checked; when the grader also tries inputs you did not see, as proven. Certificates are built from those records.
For kids, with a guardian
The kids courses are short, visual and playful — a robot factory, a rocket, a space zoo, a story machine, a sticker board. A guardian or teacher sets up the seat and stays nearby; the tutor never asks for personal details, and answers come through buttons or by voice. Read how kids courses work.
For working programmers
Intermediate courses take you from "I can write a loop" to idiomatic, tested, well-structured code in the language's own tools. Advanced courses end in Orders, a production-shaped service with validation, persistence, an API, tests, measured performance and a code-review session — the same project in every language, so switching languages later is a bridge, not a restart.
