AI-native

One AI over everything you've done.

Every answer, mistake and hint goes into one learning record. Every feature reads it, so the help you get is about you, not the average learner.

A tutor that knows you

Your skills, yesterday's work, your mistakes and what helps you. It opens from where you left off and checks your open mistakes before it explains.

What works

Worked examples help; hints rarely do

Code review as you type

Notes on the line while you write, like a reviewer beside you. A hint, never the fix.

Run it in your browser

Every editor runs your code: lessons, classes, practice and the compiler.

Practice that adapts

Questions aimed at your gaps and your mistakes, at the difficulty where you learn most.

Concept maps

Every topic as a map of its parts, coloured by what you know.

No sign-up needed

Write code. Run it. Right here.

A full compiler for Python, Java, C++, JavaScript and more, in your browser. When you sign in, a reviewer sits beside you: notes on the line as you type, and a tutor one click away.

Progress you can see

Every day ends with something you can point to.

Readiness that climbs

One number for your target role, rebuilt after every answer.

Skills, level by level

See each skill reach the level the job needs, with the evidence behind it.

Mistakes that stay fixed

Your tutor remembers what tripped you up and checks it again until it sticks.
