“Knowledge you only watched, now alive at your fingertips.”
Why xKat is different
Hands-on, not video-only
Every lesson opens a Dynamic Workspace that reshapes itself to the task —
editor + terminal, or editor + live web preview.
A map, not a playlist
Skills live in a 3D knowledge graph connected by prerequisites, so you
always know what to learn next and never get lost.
An AI tutor that sees your code
Stuck on an error? The AI tutor reads your context and gives real-time
hints and fixes.
Zero setup
No local installs. Open a lesson and the browser becomes a full dev and
execution environment with remote compilation.
Who it’s for
Learners
Explore courses, follow a personalized roadmap, and practice in the
Dynamic Workspace.
