Write real code, every day.
Semicolon teaches you to program with real code in every exercise — not abstract trivia. Eight courses, from your first bit to design patterns.
Eight courses, 24 sections deep
Speak directly to the silicon
The language the AI era runs on
Fearless systems programming
Pragmatic, expressive, null-safe
Declare the UI, let the framework draw it
The math your code is made of
The 23 classic solutions, in your language
The toolbox behind every fast program
Real code, not abstract trivia
Multiple choice, fill in the blank, fix the bug, predict the output, write the function — whatever the format, you’re working with actual code, not generic Q&A. Get immediate feedback with a real explanation — not just “wrong, try again.” A concept page is always one tap away, mid-exercise. Already know a section cold? Test out of it with a timed challenge instead of grinding lessons you don’t need.
Honest pricing
Two full courses are free, forever, no trial timer. One purchase, $24.99, no subscription, unlocks the other six. No ads, no hearts or lives, no streak mechanics designed to guilt you back in. Buy once, learn at whatever pace real understanding takes.
