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.
Sketch on your phone, let AI render it into a photo or artwork
Brush, eraser and bucket fill tools plus a colour wheel and quick colour panel give you everything needed to rough out a sketch without leaving the app.
Describe what your sketch should become with a text prompt; the AI turns rough outlines into a high-quality photo or artwork and lets you generate multiple variations.
Beyond drawing from nothing, you can feed in an image from your gallery or use pre-created sketches and templates to speed up generation.
Undo and redo brushstrokes, zoom in and out, and adjust brush sizing so you can refine fine details on a small phone screen.
