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.

Language learning built around speaking, powered by AI conversation practice
The Speak Tutor holds a real back-and-forth conversation with you in the target language and gives feedback on what actually matters, as many times as you want.
Speak flags pronunciation and phrasing problems as you speak, so you can correct habits before they set in.
Every lesson is built around the phrases and patterns native speakers use in real situations, avoiding textbook sentences and grammar drills.
The app adapts lesson order and content to your level and goals, with Premium Plus adding Made for You lessons and review built from your own mistakes.
