The lesson screen in xKat is not a video player — it’s a Dynamic Workspace: an intelligent browser IDE that reshapes itself to match the lesson’s context.

Context-aware layout

The workspace morphs based on what you’re practicing:

Editor + Terminal

For backend and CLI lessons — write code and run it against a real remote compiler, with output in a live terminal.

Editor + Live Preview

For frontend lessons — your changes render instantly in an in-browser preview.

What makes it powerful

Remote compilation

Code runs on real cloud servers, not a limited toy sandbox.

GitHub sync

Sync your work safely with a personal repository.

AI Tutor

A context-aware assistant that helps when you’re stuck.

Zero setup

There’s nothing to install. The moment you open a lesson, the browser becomes a complete development and execution environment. See Zero-Setup Environment.

Show, don’t tell

Type code and watch the terminal or preview react immediately — the workspace is designed so you experience the result rather than just read about it.
