What You Get
Everything you need to level up
Measure and improve your coding speed with the right tools
AI Explains Every Line
Finish a line and the built-in AI instantly explains what it does, why it's written that way, and what concept it demonstrates — line by line.
AI Speaks the Explanation
Don't just read it — hear it. The AI reads its explanation aloud as you finish each line, so you learn by typing, reading, and listening at once.
500+ Languages
Python, JavaScript, TypeScript, Rust, Go, Java, C++, Swift, Kotlin, and 500+ more — each with 10+ real code samples.
Real-Time WPM
Track raw WPM, net WPM, CPM, accuracy, error rate, and backspace ratio as you type — not after you finish.
Timed & Unlimited
Choose timed challenges (15s–custom) for speed drills, or unlimited mode for full-code practice sessions.
Leaderboard
Benchmark scores globally, share achievement certificates, and compete with developers worldwide.
Muscle Memory
Build real coding muscle memory — type brackets, operators, and syntax patterns until they become second nature.
Track Progress
See WPM, accuracy, and error trends improve across sessions with built-in activity tracking and historical analytics.
