Learn to code free with hands-on lessons and instant playgrounds
Short, practice-first coding lessons that run directly in your browser, so you can start learning without installing a compiler or development environment.
Dedicated playgrounds for Python, JavaScript, C, C++, Java, SQL, React, Go, Swift and many other languages let you test snippets and experiment immediately after each lesson.
Structured curricula such as Software Engineer, Frontend, Full Stack, Backend, Data Analyst, Data Scientist, DevOps and game development bundle the skills employers actually ask for.
Streak-style daily coding challenges and progress tracking help learners build a consistent habit and stay motivated between longer courses.
Undetectable AI assistant for live technical interviews
The assistant transcribes the question as it is asked and returns a working solution you can read from the overlay, aimed at LeetCode-style prompts.
Captures and transcribes the interviewer's speech so the AI can follow questions delivered verbally during the call.
The window stays out of screen shares, dock, taskbar and the activity monitor, with click-through behaviour and a disguised process name.
Targets coding, system design, behavioural, full-stack, data, AI/ML, consulting, trading and product interviews rather than only algorithms.
